I have power running from my battery to my trunk, from there it goes through a Dual-Amp Maxi-Fused Distributor Block which splits the power into 2 parts. The first part goes to a 4 channel amp that is grounded and connected to my 2 rear 6x9 speakers. The other half goes through my mono amp which is connected to a 10 inch sub-woofer and is also grounded.
From my car's stock power supply for my radio i have power running through a noise filter and then to my radio. From my radio there is an RCA cable running all the way back to my mono amp and from that amp it is connected to my 4-channel amp. The RCA cables i use are gold plated monster cables.
My four channel amp is not connected to the front 2 speakers which are stock and don't do much.
My question is I am getting engine noise from my 2 rear 6x9 speakers. What can be the cause, I hope I gave enough detail.

The Car is a 2002 honda civic, the head unit is a panasonic, the mono amp and sub are rockford, the 4-channel amp is unknown and the 6x9 are JL i believe

Disconnect the RCA jack to the 4 channel amp, if you still get it, it's in the power/ground, if not, it's probably coming from the head unit, check it's ground, you could also have a "ground loop" with the RCAs being so long, the way to solve that is to find a way to remove the outer ground shield from one end of the RCA.

Hi. Engine noise can come from the spark plugs, alternator, engine control computer, or fuel pump, etc. Make sure the speakers are grounded well (like answer 1 says) and that the amp is not a 'push pull' type which does not want a common ground between speakers (not a common problem in newer amps but check it out). Good luck!

Pioneer head unit huh? If so pioneer radios are notorious for having poor ground planes. First of all get a digital multimeter and meter your grounds the grounds should read less than 0.5 ohm of resistance. If you are still experiencing noise issues try grounding your rcas by wrap a small amount of wire around the barrel of the rca and ground it to bare metal that has conatct with the chassis. As you have noticed noise suppressors are useless until you ffind the noise source.

Bad ground on 4 channel amp. Try scraping the paint to bare metal under your ground connection. Use silicone to seal to prevent rust.

It seems that your deck is picking up the engine ignition noise. Disconnecting the RCA cables to the amp proves that it is from the deck. Have you grounded the deck properly? If the deck has a plastic cover that may be where the noise is getting in, or, it may be that the circuitry is simply 'tuned' to the frequency of the ignition. I suggest talking to the dealer who sold the deck. See if they have a fix available.

put your rca's on the other side of the car and away from your power wire
and no you didnt give enough information
