high pitched whine? (redid grounds)

[soulnomad 10+ year member]

I had one hifonics bxi1606D installed and never any grounding issues or ground loop related whines but ever since i installed my 2nd 1606, I've been having whining issues in only one amp. I resanded my grounds and the timbre of the whine changes when I roll up my windows. I just did big 3 and my voltage seems fine, any suggestions?!

pioneer deck? see if its the RCA's by using another pair and seeing if the noise still exists. check the remote wire

alpine, but ill check the rem. thanks

 

[soulnomad 10+ year member]

the amps are daisy chained and the amp making the noise is the one that is receiving the first amps signal

check the remote wire

[hijack] I have a non-pioneer deck and some squeel... what do I need to check on the remote wire? [/hijack]

rca's crossed with any power cables?

 

[soulnomad 10+ year member]

they are about 7 inches apart, also the other day i heard the noise and pushed down on the other amps power and ground cables and the whine went away and now it seems like it switched amps

everything your said, it still sounds like a grounding issue to me! what i would do is tie the grounds of the amps togeather and run them to the batt. ground and see what happens. if it still whines i would check the alt.

^ he said the voltage was up tho so grounds shouldn't be the issue. I think it has something to do with the rca's. Undo the daisy-chain and see if either amp has whine by itself. the first amp might have bad rca outs or the 2nd amp might have bad rca in's

i agree with the rca issue. what i would do is undo every ground from the amps and tie all those wires together and run them back to the battery;especially since you already did the big 3. after that i would say you dont have an rca problem.

one more quick question!could rca's still be an issue though because i only hear the sound when the engine is running? (not when playing on acc, then there is no noise)

well i had bad whine out of my pioneer deck! i took speaker wire and striped it and ran the bare wires around the metal part of the rca's and then grounded it to the radio on a screw! and it took it all away!

id try that

and frame ground always help!
