So I blew up my alternator cleaning my engine (stupid me), so now I am looking to get a little higher output alternator for my 97 legacy. I already have pretty bad speaker whine and have been to 3 different shops and they couldn't figure it out and have looked at near everything myself. My set up is an 8ga to my cap that powers my 450w amp to 10"cvx and another 8 ga to my 400w to my 4 speakers. My alternator is directly grounded btw. This weekend I installed hushmat and did some other things to my car to clean it up and thats when I blew the alt. from cleaning the engine. I also cut the 8ga to the 400.4 and hooked that up to the cap as well, which now I realized is stupid because I have less power cable to my stuff. My logic at the time is that the 1 farad cap could handle both the 400.4 and 450.1 and the 8ga would slowly keep the current coming into the cap. and I may just see more voltage drops, but the strain is directly on the cap. now and not on the battery and alt. Is this correct or did I put more strain on the alternator since it is struggling to keep the cap and amps at proper voltage?
K so I know my stuff is all F'd, but I plan to do big 3 and run a 4 ga or bigger power cable to my cap. when I get back to working on my car. So if I put in a higher output alternator, won't I hear more speaker whine? I want to have a good alt. for my system, but all the work I have done will be worthless if I have any more whine as it is already driving me nutzzz!!!! Could the whine have been because I didn't have the big 3 before and there was a lot of strain on my system? I would love to track down the root of the problem, but I have done near all I can and am about ready to install a ground loop isolator to fix it. Sorry if this was hard to understand. Ask any questions and ill reply quickly. Thanks in advance for sharing your knowledge/experiences.
