Last night, after 4 days of work (obviously had issues ...) I picked up my car after a 4 speaker and 5 channel amp upgrade. The car is acting a little strange.
The ease of access doesn't work when the car has been left alone for a while, that is you can't open it with touch you need the key, also the 'douche' driving lights don't come on when you unlock anymore.
Trying a second time it works. There's also power draw when the car is on ignition and switches itself off after 1 minute.
What i'm more concerned about is some whirling (non mechanical, more power) noise coming from the front of the car the more I accellerate the louder it gets!? (I really don't remember this noise!?!?!)
I am obviously going to call but would like to be armed with any info before I do!
Thank you kindly,
P.S. I'm not going to name the install (yet) but it was a custom specialised and 'reputable' installer, said he'd worked on them before but now not so sure.
The whirring noise might be a bad ground; get them to check it again.
Remove the fuse from the amp and see if you still get that noise.
Tell us more about the upgrade. I did my own, and had no real issues.
