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 […]

Audi TT Magic: Sound System Upgrade

I have worked on a lot of TT’s over the years but this has to be one of the cleanest! I’ve known the owner for many years, and have worked on several of his cars. Initially, this Audi TT was only going to be a simple bass upgrade but things soon escalated… Assessing the sound […]

BMW M2 Upgrade: New Year, New Sound System

The BMW M2 series F22/23 is a fabulous coupe. However, it suffers the same audio fate as the rest of the BMW range: terrible music reproduction. Whether you have the base audio system or the ‘upgrade’ Harman Kardon ‘hi-fi’ the audio performance is bad. Generally, the sound lacks sparkle or dynamics with poorly defined stereo […]

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 […]

Say ‘Hello’ to our little friend. She’ll blow you away!   Anyone who knows us at Car and Home Stereo will probably know about my Mk2 Golf GTi. I’ve owned this car for nearly 18 years and in that time it has had several jaw dropping audio installations. Every version has left a lasting impression […]

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.

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 […]
