Frequently asked questions

  • Our packages have been designed to make the process as easy a possible for you. If you are stuck on what is best, just call us or visit us so we can guide you. We are here to help.

  • Installing aftermarket speakers can be a great way to improve sound quality, loudness, clarity and increase the frequency spectrum or fullness of the sound. No manufacture system like HK, B&O or Bose would ever be able to compete with the products we use. the reason is, they have become so mass market and in turn have to fit a price point for brands like BMW, Audi and Mercedes.

  • Subwoofers add bass and depth to your stereo's sound. And they can also add to a system's performance in a variety of ways. A quality subwoofer will add depth and realism to your music that you would otherwise miss out on with a factory car stereo system. The old days of filling your boot with massive subs has gone, we focus on more of an oem look with incredible sound.

  • Every install will vary massively on the level and amount of equipment that is being used plus the level of fabrication that is involved. We have made this simple by adding an estimated time scale onto each package that we have designed. We do strongly believe in, do the job once and do the job properly. Perfection can’t be rushed.

  • YES! With the EV market massively growing, we are carrying out more and more sound system upgrades to EV cars. The most popular question we get asked about EV Car Audio is ‘will the range of my EV be affected by a new sound system’. We have done testing on this and have designed systems using the latest technology in car audio with extremely low draw which is designed to not impact the range you have on your EV.

    Electric car audio upgrades are fast becoming our future and we are one step ahead of the game. With one of our demo vehicles being fully electric. Sound system upgrades for electric cars is no easy thing to do however our team have experience and knowledge on this so you know your EV is in safe hands.

  • The packages we have designed are fantastic BUT it is so hard to gauge what system is best by looking online, that’s why we always recommend you come to meet with our team so you can experience every detail. We give a full workshop tour of our 11,000sqft facility so you know that your car is in safe hands, then we listen to your car, then you listen to our demo car, then we sit down and go into every detail of the system and can tailor something for you to get you the best car audio system.

  • Tuning a car is an artform in itself. After the install is complete, we use an RTA machine to asses if there is any noise cancellation and to get a better understanding of what the system is doing. From there we use 5 microphones as a part of the Bit Tune kit to give a precise time alignment for the optimum listening position. Once the Bit Tune kit has done it’s alignment and created an EQ Curve, we then sit in the car and fine tune the system by ear. On each system where we have a DSP in the system, we take a few songs from our client and then fine tune to those songs.

  • Not to worry, your car an still be upgraded by us. Most of our clients travel between 2-6 hours on average for installations of audio upgrades. We have many clients from areas in London, Birmingham and even in areas in Scotland. We have found that our clients don’t mind traveling for amazing craftsmanship and work. It is our job to make the process as easy as possible for you.

    We have Hire Cars available or alternatively we have transport firms that we have used and trust that can arrange collection and delivery for you!

  • We have many international clients that wish to have their vehicles upgraded by us. If you are based in Dubai, Europe or the USA, we offer plans to have the vehicle delivered and collected from ourselves. We normally work with this business:

    Ship My Car

    info@shipmycar.co.uk

    +(44) 1908 887 917

    International clients of ours in the past have either used this business to transport their cars, or alternatively used their own transport. If you are looking to have your vehicle upgraded with us and you are based internationally, please mention this to us in your initial enquiry and we will assist you with making everything happen.

Trusted by celebrities

The Porsche 911 993's audio system is a major disappointment given the age of the vehicle. Despite being a highly sought-after classic car, the audio system fails to deliver the level of quality and functionality that many drivers expect. One of the biggest issues with the system is road noise, which infiltrates the cabin and detracts from the audio quality, particularly at higher speeds. The speakers are also underpowered and lack the clarity and punch that many drivers expect from a premium car. Additionally, the audio system lacks advanced functionality and connectivity, making it difficult for drivers to play their favorite music or podcasts. The lack of Bluetooth connectivity, for example, is a common complaint, as it makes it difficult to stream music from a smartphone or other device. Given the age of the Porsche 911 993, it's understandable that the audio system may not be up to the standards of modern cars. However, it is still a major disappointment for many drivers, who expect better performance from such a revered classic car.

If you are looking at upgrading the sound system in your Porsche 911 993 then have a look over some of our packages and then book a consultation so we can advise on the best solution for you. We always recommend that you come in and see us so we can guide you and even design you a custom system that sits in between on of the packages that we have on the Cambridge Car Audio website!
