My belt squeels when the lights are on, so probally the alternator sucks or is going bad, either way it looks like shit cuz its the origonal. If I go out to buy a new alternator what should I get, I kind of want something with plenty amps cuz I want a new sound system
I bought a 115A aftermarket alternator when I didn't know much about my car. Ever since I've been working on my car. I installed a new sound system with PPI amp, 2 6x9" rear speakers (!) and orion 4x6" front speakers, and a 200W Rms Infinity Subwoofer. The system works just excellent. But be sure of: having at least a 90Amp Bosch alt (which is good), have at least 1F Cap, and make sure your grounding for the amp and cap is good. I mean real good. I only drilled a hole and screwed the 4G Power Cable's connector directly. But the amp would lose power and turn off for a second or two. I then scraped the surrounding of the hole that I connected the power cable's connector to elimininate the thin coat of the metal which kind of acts like an electrical insulation. Now the sound system is worked perfectly... Good luck!
