Porsche Boxster Audio Upgrade.

The Porsche Boxster S is a superb car which offers exciting top-down performance with practical everyday driving capability. Unfortunately, the audio performance leaves an awful lot to be desired especially the base version that is only equipped with dash speakers.

The biggest challenge, of course, is the convertible top because as soon as that is raised most of the sound and pretty much all the bass disappears. Car audio in a Porsche for some owners is not a priority but for this customer, the lack of a decent sound was spoiling the drive so an appointment was made to discuss options.

Step One:

The first choice to make was whether the original head unit was to be changed. It is completely possible for us to use any original factory unit as a base for great audio but in this case, the basic Becker unit was certainly past its best so a decision to upgrade to a top of the range Pioneer unit was made.

The Pioneer AVIC F88DAB is a full house unit boasting a 7-inch screen, full satellite navigation, DVD, CD, SD, Bluetooth, dual USB, DAB radio, Apple Car Play and Android Auto. Its comprehensive external connections make it ideal for use as a high-performance head unit in a sophisticated audio system. It also boasts a very powerful set of audio controls to allow accurate tuning of the system.

Installing this double din unit means relocating the heater controls to the lower console. We use an American kit that costs a little more than others but is of a far superior quality with a factory standard fit and finish.

Once we had relocated all the standard wiring and removed the remnants of an old ‘phone kit we could start the new wiring. When we install new looms we always wrap them in OE quality fleece tape, this ensures a factory look but most importantly eliminates any possibility of cable rattles. Where cables go through the bulkhead grommets we make sure to use silicone sealant to prevent any water ingress.

What next?

Once the looms had been installed we could start the hardware installation, first was the amplifier. Originally this Boxster had a CD changer mounted in the bonnet just behind the spare wheel; since this would be useless with the new head unit we removed it to locate the Hertz DPower 4 amplifier.

This amplifier is an absolute gem with over 100W per channel on tap it is perfect to drive the dash speakers and subwoofer. Although it is well equipped with filters to tune the system we will use the crossovers and EQ available on the Pioneer F88 to really fine tune the final sound. Again more cloth tape keeps everything neat.

Once the amplifier was in we could install the dash speakers. The dash location allows for a separate mid and tweeter under the original grille. However, as there was only to be a single channel input per side there was no advantage to splitting the drivers up and so we chose the Audison APX4 coaxial speakers.

This speaker really is surprisingly good.

At only 4 inch diameter it is capable of a really good bass response and when powered by a good amplifier it delivers a very accurate and responsive performance. This is all the more impressive when you consider its relatively low price. They are not a simple plug and play replacement though and we needed to construct a new mounting system under the grille to get a perfect fit, of course, this is no problem for us.

As good as the Audison APX4 speaker is it is only a 4 inch and cannot be expected to deliver the bass requirement for a convertible car. We have had a lot of experience with convertibles and one of our solutions where space is tight is to custom fit a JL Audio 6w3 into the passenger footwell. This magnificent speaker is capable of delivering more than enough bass from a very small enclosure.

The trick is to very carefully control the frequencies it plays to achieve a seamless blend with the mids. As we construct our own enclosures we can design each one to perfectly fit the car we are working on. For this one, we even wrapped it in genuine Porsche carpet to ensure a true factory look.

Very little space is taken up meaning there is no significant constriction of the passenger foot space. The enclosure is secured to the car using invisible fittings which means it can be removed without leaving any marks in the carpet or trim. Once the floor mat is cut to shape and trimmed it will look as if the sub had always been there.

Pioneer AVIC F88DAB:

One of the great features of the Pioneer AVIC F88DAB is its powerful equalisation controls. This luckily features two EQ pre-sets. This allows me to tune two EQ curves; one for roof closed and one for roof open ensuring the best sound regardless of the vehicle’s configuration.

I really enjoyed this installation;

it was relatively simple but really delivered above expectations. The sound was full and rich with as much bass as could be needed. The new head unit was feature rich and the owner fell in love with Apple Car Play instantly. The dash-mounted Stormtrooper is really going to enjoy the miles now!

VW Golf 7 Audio Upgrade

Following on from our last blog we have an example of a car audio installation to a VW Golf 7. This is a perfect example of how one of our standard systems is adapted to make sure the owner gets exactly the sound he wants.

As our customer lived a good way from our shop he decided he wanted the whole job done in one rather than splitting it up to spread the cost. Initially, we started to talk about our stage 3 upgrade.

Fortunately, our customer already owned a JL Audio HD600/4. This magnificent amplifier is one of JL’s finest boasting very impressive power figures with incredible dynamic range.

This was an ideal amplifier for a really high-end system; he liked it loud but did not want any distortion when playing his favourite dance music. Since this amp was so good we felt we should recommend an upgrade to the front speakers over the Hertz MPK 165 initially suggested. The owner wanted clarity without colouration and his preference was for a very dynamic high frequency. My recommendation was for the Audison Voce K6 component set.

These speakers are one of my favourites and offer a truly natural sound. The tweeter is larger than some but this helps to give it a remarkably low-frequency capacity meaning a better blend with the mid-range.

We opted to stay with the usual Audison APK165 components for the rear fill. These speakers are a fantastic upgrade to the factory standard at an extremely good price. However, he was happy to upgrade the sub to take advantage of the power available but did not want to lose too much boot space. The obvious choice was the JL Audio 10TW3 in a slim enclosure as this will deliver smooth, powerful bass from an enclosure only 12cm deep.

So to the installation.

Our customer did not want any more boot space taken up so we had to locate the other equipment in the cabin. We knew the amplifier would fit under the passenger seat but this left no room for the Bit10D; that would have to go under the driver’s seat. We also chose to situate the crossovers for the front speakers here as well. This of course added to the complexity of the wiring but by using high-quality speaker cable and double shielded RCA cables there was no chance of any interference or quality loss.

The doors got a complete treatment of Dynamat Extreme and Dynaliner to optimise the acoustics and eliminate any chance of rattles. We built custom collars for the speakers ensuring they were sealed to the panel to maintain moisture protection.

The rear door tweeters are in the door panels but the front ones reside in the A-pillars. We constructed custom mounts for both of these.

Important note.

When removing the VW A-pillars the retaining clips must be replaced with new items as they are an integral part of the airbag safety system and removing the clips compromises their integrity.

The final part of the installation meant mounting the Audison DRC and the location chosen by the customer was the small fold-down tray to the right of the steering wheel.

This location is convenient to use but renders the installation invisible when closed.

The next task was to tune the system. We already knew he liked a bright, dynamic sound so we programmed it for a lot of energy in the higher frequencies without getting harsh. The bass had to be tight and punchy and the TW3 does not disappoint. With so much power available we could keep the gain on the HD600/4 at almost minimum giving the highest dynamic range.

Of course, the speakers will require a week or so of running in before a retune but the owner’s initial reaction was ecstatic. It was all we could do to get him out of the car to register his three-year warrantee!

As mentioned we have standard packages that we can recommend but a great many are customised by us to make sure you get exactly what you want from your new car audio system.

Looking at Volkswagen systems

I am often asked what system I would recommend for a certain type of car. My answer is usually that it depends on the type of sound and performance you are after. That is certainly true but there are some constants and I think it will be useful to discuss these over a few installments.

For the first one, I will choose the latest VW Golf.

 

The Volkswagen Golf Mk7 is a fabulous car but the audio system leaves a lot to be desired. Even the so called upgrade packs are disappointing and certainly not worth the premium charged. The large screen infotainment system in the dash is certainly smart but does not have a particularly good audio performance while the speakers deliver a lackluster sound at best.

So what are the options?

If you choose to replace the head unit (and we highly recommend it) then the absolute best choice is the Alpine X901D G7.

This exceptionally high-end unit is specifically designed for the VW Golf 7. It is a perfect fit and will support all the existing VW systems such as reverse images, steering wheel controls, and vehicle information displays. The performance leap of this machine over the standard system is amazing and is the perfect base to add an upgrade audio package.

However, you may not wish to change the head unit and we would completely understand this. If your car is leased or on a purchase plan it may be best to not change the look of the vehicle at all.

Fortunately, we have developed several audio packages that can be invisibly added to your car that will massively improve the sound.

The Audison Prima pack:

This specific kit is a true plug and play solution from the masters of OEM integration, Audison. The kit comprises their DSP amplifier with built in EQ presets for the Golf, replacement front door speakers, discreet subwoofer for the boot cavity and all interconnecting cables meaning that nothing needs to be cut or changed. At a little over £1000, this is amazing value for money and sounds far better than the VW dealer upgrade options. Although we would strongly recommend it the sub is optional and if you choose not to have this then the price is even lower!

As soon as you hear this you will notice the massively improved clarity, the sound stage will be higher, wider and more surrounding. The bass will be stronger with a much better punch without being ‘boomy’. Of course, all of this can be removed when you come to change the car and with a little reprogramming can be made to suit whatever car you purchase next making this a much better investment than the dealer options.

At Car and Home Stereo, we have also developed our own upgrade options drawing from the best products from around the world. For convenience, we describe these as Stage 1, 2 and 3 but of course, there are variations to take account of personal tastes and requirements.

Stage 1:

This is full speaker upgrade pack based on the 5 door Golf. While the choice of speakers could change the acoustic improvement products do not. These are as important as the speakers themselves in maximising the performance of the upgrade.

The full kit comprises Hertz MPK 165 front component speakers, Audison Prima APK rear component speakers, 4 sheets of Dynamat Extreme sound deadening, 2 sets of F.A.S.T. acoustic foam sealing rings and 2 sets of speaker mounting collars.

The cost of the stage 1 upgrade is only £650 with an installed price of £900. Even on the standard VW head unit this sounds amazing with improved clarity and bass performance. The performance detail is also improved thanks to the far more sensitive speakers and the acoustic treatment in the doors.

Stage 2:

This is a stand-alone sub and amplifier package. As you can imagine there are many to choose from but there are two that we have found to be highly suited to the Golf as they are powerful but take up a relatively small space in the boot.

Stage 2a is the Audison APBX 8R slim sub enclosure and the small but powerful Hertz DPower 1 amplifier.

This offers 600W output and will tuck into one side of the boot taking up almost no space at all and at only £479 for the two it represents great value for money.

Stage 2b is the same amplifier but married to the fantastic JL Audio 10TW3 sub in a slim enclosure. This sub is exquisitely musical, a real hi-fi experience and this package adds up to £650.

This amazing, compact sub can also handle a lot more power if you are a real bass nut!

Stage 3:

This brings everything from before and adds amplification and processing to the entire system. There are again two recommended packages here.

Stage 3a uses the Audison AP Bit amplifier. This incredible amp with built in processor is tiny and powerful, quite capable of driving the entire car system. The on board processor allows for perfect tuning of the sound stage to suit anybody’s taste. The phase and time alignment controls mean the sound can be focused to wherever it is needed making for a wide and spacious soundstage. These amplifiers start at only £600 so represent tremendous value for money.

Stage 3b is a combination of the JL Audio FiX 82 processor with the JL Audio XD400/4v2 amplifier. The processor is specifically designed to automatically compensate for original head unit anomalies. It will take out any spurious EQ that has been added by the factory radio as well as eliminating any unwanted phase changes. It also allows for personal tuning via PC to really dial a system in. Once the processor has cleaned the signal up the XD 400/4 amplifier delivers the power. This amplifier has become one of my firm favourites offering tremendous, clean power from a very compact chassis.

This package is slightly more expensive at £750 but does offer a higher level of performance.

As I mentioned earlier these packages are extremely flexible to suit individual requirements but I can heartily recommend any one of the above. We have installed many of these systems and know that they perform brilliantly.
