ok my friend bought a 2g, (because it looked cool).... we all know where this car is going. ANYWAYS.. It's rice. he added a sub system, and when it's on there is a constant squealing noise and the noise gets faster when the car speeds up. and when the system is off, the noise is gone. I told him his alternator is too small, but he doesn't belive me, am i right or wrong here?
