[QUOTE="mendon mafia, post: 7538701, member: 584590"] I would also like to add that the noise persists even if the engine is off. I am using 2 runs of 8 gauge (100% OFC) linking the amps speaker outputs and there about 4-5 foot long each and then dual 8 gauge into the sub from each amp. the speaker outputs are completely full of wire on both amps, i dont think this is the issue. The RCA is knuconcepts klarity and 1 meter long unless i use the barrel then its 2 meters long but still knu klarity. For the big wire touching the heat sinks, do you mean link the heat sinks together or ground them to something? I thought that was the problem a while back with my HU ground so i added a ground (also have the stock ground hooked up) from the HU to the nearest bit of metal with 3' of 8 ga. Im not convinced this is a great ground but wouldnt I have noise even when not strapped if it was the problem? I will try to ground the chassis of the amps to something but isint the negative terminal hooked to the amp chassis already? both the amps are grounded directly to my battery bank in the trunk (just one for now but i have 3 usually) and i have 2 runs for + and 2 runs for - from front to back one set is off the front battery the other is direct from the alternator, big 3 (4 in reality) has been done. All the power wire is 1/0ga 100% OFC. My car has ~100' of 1/0 just for the charging system. The ground wires are about 6' long for each amp but if that was the issue wouldn't i have noise when not strapped? Do you really think grounding one of the amps to a place other than directly to my rear bank will help? seems to me that the bank is my best bet with my copper buss bars and all. The bank itself is also grounded to the body of the car in the trunk with 1/0 ofc in addition to the dual 1/0 grounds from front to rear. [/QUOTE]
