[QUOTE="ThxOne, post: 8679853, member: 675210"] If I recall... from working at 3 of the major auto parts stores over the years for several years... the 88 has the 3.8L V6 with a 140a alternator. Buick uses a lot of electronics but not the total output of the alternator at all times. That car should be able to support a decent system without issues. If you are getting dimming lights start from the least expensive thing (free) and work your way up. #1 CHECK YOUR GROUNDS!!! then make sure your cables are of adequate size for your system load. Make sure your cables are TIGHT at the battery. Make sure your subs are wired for the correct ohms load. Make sure your gains are correctly set. In my Jeep, I have a 125a Alternator and my voltage dropped horribly. It was a bad ground.
