Looking for some advice after audio upgrade
Discussion
Hello
I recently had a new audio system installed into car to replace the native HK sound system that came with the car. I was pretty pleased with these results however every time I got into the car the speakers would omit a loud static discharge before I started the engine. I spoke to the company that fitted them and they said this is totally normal so whilst it was a bit annoying and unnerving I kind of accepted it for what it was. However subsequent to the fitting the front left door speaker cackles at times and doesn’t output at all other times and a couple of weeks ago I lost all sound in the car. I’m booked in for them to take another look but wanted to see if what I describe about the static is considered normal or not?
Thanks

If your car had HK then chances are if you have had a good hifi fitted you will have an Audison DMI installed. This is the device that extracts the digital audio data on the cars MOST ring and spits it out via a TOSS link to a DSP.
There are two ways of configuring the system to “Wake Up” or “switch on”
If the remote out of the DMI is used then the system will normally only switch on when the ignition is full on. The advantage is that this generally hides any pops and other strange noises that occur as the modules wake with no audio playing. The disadvantage is that if you press the radio button to listen to music / make a phone call, without the ignition on there is no sound at all, the I drive is working but silence.
The second way to turn on the audio system is by using the cars actual “wake up” this means the system switches on as soon as the car is unlocked, perfect if you want to use the system without the ignition full on. The system will will then switch off shortly after the car is switched off or the doors are locked. This is generally the preferred method, although you can sometimes hear the odd pop or hiss as the system wakes, never during use.
I am certain if you speak to the installer they could explain this and reverse it if you preferred.
As for the audio fault that’s really annoying but sometimes stuff can go wrong, again your dealer may offer a lifetime warranty on their installations and are probably desperate to get it fixed for you. Most good car audio dealers take a lot of pride in their work and will be gutted if their customers have a problem.
Hope this helps 👍
