True, we use powersupplies to drive and charge these systems, though many of the vehicles we compete in are still daily drivers. Regardless, the alternator is tested with a multi-meter. Very easy.Originally posted by tad_02Wgn
the electrical system of a competition vehicle is quite different from that of a daily driver... try charging a trunk full of batteries on a stock alternator.
Although I do agree with you on getting the charging system tested.
The alternator upgrade is really not that necessary. I'm running a pretty big system, RF 5002 and RF4004, with Kove Opulent Components in the front and matching 4" rear, with a T3 sub in a custom box. I have had no problems.
The most important thing to remember when it comes to soundsystems is proper installation. Bad install's make up for more than 90% of the problems we fix at my shop.
