Got a power inverter in my trunk and I think it cause feedback however I'm not sure its that here s the deal:

I'm using a volfenhag 4 channel amp to power 4 interior speakers. THere is only feed back on one set of RCAS, I've replaced them and everything for example if I take the front RCAs and put them in the Rear and vice versa the feedback goes into that set of speakers and vice versa....

Thinking bout using my amp as a 2 channel with just one pair of RCAs and bridging the speakers into 2 channels...

Think this will help?????

Also when I leave the rear speakers on lpf low pass filter then the feedback dissappears however I can't hear any highs from the rear and when I put it on HPF high pass filter I hear the highs along with feedback...

Please help me...

What makes my car Bang:

Kicker KX 600.1 Mono amp (2004)

Long Ported Box Single

Kicker 200.4 4 Channel(2004)

Feedback? Can you describe the noise? Is it alternator whine?

Does the RCA run alongside the inverter? Do BOTH RCAs run alongside the inverter? Is the noise only present when the inverter is on? Can you relocate the inverter? Where are the RCA's run otherwise? Are they near a high current device elsewhere in the car? If you swap the RCA's at the head unit, does the noise change to a different set of speakers as well, or remain in the same pair? If it changes, you have a problem with your HU - not the RCA cables. Are you using a LOC anywhere? Is it a good quality one?

Check some of these suggestions, and get back to us...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
