Question about 2007 Pontiac G5 Gt Coupe
I have a 2009 Pontiac G5 GT with aftermarket subwoofers, 2-12inch subs. So when I have the bass on loud the indash lights, mirror lights, and even headlights flash when the bass pounds. The subs are in the trunk and in this model so is the battery. The subs are hooked up to their own amp, and my stereo guy has assured me they are wired in properly.
Is this bad for the car? I have had the car for about 2months but have only noticed this issue in the last day or so. Should I be worried and get the car checked out?
Thanks for the replies....
Look into a capacitor for your amp.

So your lights flash. big deal. I have seen alot of guys get bigger alternators and stiffening caps. the battery in the trunk.. very nice.
seriously i think it might not be a simple one fix answer.. higher amp alternator may have higher cut in rate. you may need to rev higher to get the juice. are you using a d-class amp or a wasteful a-b class. you must have heavy wiring and in short lengths i hope.
what kind of battery do you have? when was the last time it was full charged.
throw on a charger if you have a decent battery. - optima.. or anything high amperage.. the battery is important the alternator should be ok.
look into a low cut in alternator. even of the same amperage
