I just hooked up a JL G4500 for my door speakers in my car, and when nothings playing, i get a high pitched whine from my speakers. it gets higher pitched as RPM's go up. its annoying the living hell out of me. can anyone tell me whats causing this or how to get rid of it?
That is actually what I was going to bring up later on but, since you mentioned it now, lets talk about it. If you have your RCA's running along side your Power Cable regardless if it's top notch or not, you may experience that humming noise.
I would suggest re-wiring the RCA cable on the opposite side of the vehicle. If you have already done this, I would make sure that all you cables are secure and nothing is exposed/cut/damaged.
If it's still happening, and you have an extra pair of RCA Cables, go ahead and swap em' out. See if it helps. If none of this helps, let me know. There are a few extra things you might be able to do.
well the problem with my subs is fixed for the most part. i invested in some nice RCAs from knu. but the problem im having now is with my front stage amp. But im pretty sure its the ground. ive got it grounded to one of the drivers seat mounting studs.
they dont run along side of the power cable though. the rca's come down out of the bottom of the dash and under the carpet to the other side of the amp. the power cable comes out of the firewall on the far drivers side, runs along the kick panel under the carpet and hooks into the back side of the amp, opposite of the rca's. they cross in 1 spot.
found out why i had alternator whine! the power wire crossing my RCA's for the 4 channel wasnt doin it. It was because i have my cheap RCA's running right along my 1/0 run for my subs. but because of the low pass on the head unt and the amp. its getting filtered out on the subs. but i guess it was feeding back in the head unit and sending the buzzing to my 4 channel. I got a cheap noise filter from sonic electrix, to hook into my 4 channel RCA's but i found out when i disconnect the RCA's to my subs, the whine stops. so i put the filter in those RCA's since it was a lot easier, and no more whine!
i thought it was a bad ground at first. so i regrounded it and it did nothing. so then i thought it was the rcas. just turned out to be the other set of rcas. but that stupid noise filter made my bass quiet. so i now have to get some couplers from radio shack so i can hook them into my 4 channel rca's because the input is male and output is female. and i need the opposite
yeah im gunna try something like that. i think first im gonna just run the rcas on the opposite side. that should do it. if not then ill invest in a nice set. haha these were only like 5 bucks from knukonceptz
