Alt/engine noise

[eriley]

I know, I know use the search button and I have and read as much as I possibly could and tried pretty much everything that was said...but I still have alt and engine noise coming through my speakers. Everything is grounded to the frame, my RCA's are on the other side of the cab from my power wires, I tried grounding my RCA's which actually helped a little but I guess I'm retarded because the way I grounded it caused my radio fuse to blow (not the head unit one the one in the fuseblock) so I nixed that since it didn't completely stop the noise anyway. Either way my question is, could the noise be caused by my cheap amp? I basically pulled an 8" clarion sub out of a premade truck box for an F150 and used the little 100 watt (I think) amp that came with it. I got the premade box for free and needed something to use as a template for my console/sub box I was building since I won't have the money until next summer to get what I want. And I figured since I have it why not use it. Sorry for the book, just trying to explain my situation so that I don't get flamed as bad as I deserve.

i said this in a different thread....try grounding your RCAs to the back of your headunit. all you gotta do is wrap a piece of wire around the metal part of the RCAs and touch the other end to a ground. See if that works

What ground do I ground to? I read that you need to ground to the head unit but when I tried that it popped the fuse everytime.

edit: change that I mean where at on the headunit, before I just wrapped it around the RCA and then put the other end under a screw on the back and it popped the fuse.

really? thats interesting.......never happened to me before. try moving the ground to a piece of metal in the dash somewhere.....

well it might be your power wire i would check all my power connections starting from the battery to the amp that was my issue that i had to change out my fuses and my noise was gone

I regrounded my RCA's and most of the noise went away like before but there is still some.

Could possibly be the inputs on the amp.

could just be interference from an mp3 player if thats what your using.

nope only thing I have are cds and radio.... I'm thinking its just because it is cheap... I'm doing a lot of research over the next year and then I will build a much better system, well hopefully it may take me a couple years to do it since I'm on a really low budget but once I build it I don't plan on redoing it over and over I wanna do it right the first time.
