[QUOTE="matinm90, post: 7505643, member: 636240"] Hi guys, so up until now I only had one amp for my subs and my speakers were running through my receiver. So now I have a separate amp for my speakers, the power for both amps is just one wire from the battery into a power block and of course one wire for each amp, the main wire is hidden in the trim on the left side of the vehicle, and both amps are connected on the left side as well, the RCA cables are also on the left side. I'd say they are maybe 7-10 inches to the power wire coming from the battery. The ground wire is connected underneath a bolt in the rear, so the third row seat has a long metal thing at the base of the seats, and both grounds for the amps are along the same metal rail -idk what to call it, BUT at different points on this rail, and finally as for the receiver that is just grounded like any other receiver, the one that comes out from the harness, nothing special, now this is the interesting thing when the engine is off, I hear a slight buzz but it isn't that bad, when the engine is on the noise is much worse. Any thoughts? Btw I think I've proved it's not an alternator issue. And thanks guys. [/QUOTE]
