Harman Kardon shortage: BMW

BMW is a renowned vehicle manufacturer. I’ve owned quite a few in the past and my eldest drives a 330ci E46. I still take every opportunity to drive it and love its connection to the road. That car came with the upgraded Harman Kardon audio pack and while it sounded OK, we have swapped that […]

Porsche 997 audio upgrade with Audison and more

The iconic Porsche 911 has been around since the 1960s. Since then, it’s remained faithful to the original design ethos and is still instantly recognisable. It’s a great car that’s at home both crossing Europe on the Grande Tour or popping down the road on the daily commute (remember those?). The 997 variant appeared in […]

Boxster Magic

At Car and Home Stereo we have worked on just about every type of car over the years but ones we see a lot are the Porsche Boxster and Cayman. These fabulous cars are a joy to drive but the sound system is sadly lacking especially if the standard head unit is the CDR24. The […]

Installing speakers – how hard can it be?

As modern cars have got more and more sophisticated you might have expected the audio performance to have kept pace. Sadly this is often far from the truth; vehicle manufacturers are still installing woefully inferior speakers. Why are they doing this? Because they are cheap. Compare the standard factory speaker on the left with a […]

New car audio products from Pioneer, JL Audio & more

In fact, it never ceases to amaze me how innovative our industry is and how we manage to stay ten steps ahead of the car manufacturers. In this blog, we will look at some of our favourite products that are new this autumn/winter. Pioneer […]

Bentley and Mercedes audio upgrades

Modern vehicles often have very sophisticated information/entertainment systems built into the dashboard. In a lot of cases it would be just about impossible to change this and besides, why would you want to? They usually look great and offer large clear displays with all the features you could want. A great example is the VW […]

Audi TT Audio Upgrade

The latest Mk3 Audi TT is packed with technology and has a very sophisticated infotainment system installed as standard (it desperately needs better speakers but that’s another story). But what of the Mk2 TT? Still a great car; but the old Chorus, Concert and RNS-E navigation systems are certainly showing their age. Regardless of whether […]

Amplifiers: The heart of the car audio system.

In its basic form an amplifier has one job, to take a small signal and make it bigger. This would be so easy if music looked like the above sin wave but of course music is much more complex. Music is a complex mix of multiple frequencies with varying levels and shapes. Sin waves, square […]

Improving the BMW audio

We have had a lot of calls recently from owners of newer BMW 1, 3 and 5 series vehicles complaining about the very poor sound quality of the factory audio system; even those with the Harman Kardon upgrade option. Some have described it as the worst sounding system they have ever heard! We have carefully […]

Sub-woofer: bass in not much space.

There is no getting away from the fact that every good car audio system needs a sub-woofer for a full range sound. By their very nature a sub-woofer needs to be large to play the frequencies required and it will also need to be in some kind of enclosure. So we have a large speaker […]
