I Just installed a 1700 watt kenwood class D amp in my 03 honda accord. I have it hooked up to 2 punch 15 speakers. When I turn my radio or car off My subs just drop into a low Pulse of constant bass. The only way I can make it stop is if I turn my amp all the way down. Can some one please tell me what the problem is?

By the way the RCA connections are from a step down.

ok you do realize that the gain is not a volume control? sorry i just have to eliminate the obvious....im also assuming since you are using a step down that you have done something creative to pick up a remote wire to turn the amp on...my guess is that your remote wire is carrying enough voltage to keep the amps on and that either you have the gain at the step down incorrect or the amp gain incorrect or both......did you buy a quality step down or a cheap one?

I realize the gain is not the volume but that is the only way i can fix it as of now. I got the step down intalled buy this wack car audio place. It might be cheap. Any sugestions on a good one? So i can adjust the gain at the crossover? And i will also check my remote wire. Thanxxx

your amp i think has a built in crossover or are you using an external electronic crossover as well? i simply meant that if turning the gain down fixes theproblem maybe that is part of the problem...people have a tendency on sub amps to crank the gain on a sub amp especially trunk mounted systems or systems that have a cover over the hatch, reason being you cant hear the distortion as well. as far as step downs go audio control has a real nice one that takes your input and gives you true preamps.....i am not a fan of them, they are never as clean as a true signal and you can generally get better sound with even the cheapest of head units as long as they have a preamp output......before i dropped money on a real expensive converter for your factory head unit i would look into an aftermarket unit...

could be a bad ground point
cound be a damaged amplifer (common with kenwood)
could be the gain being set too high
could be that line out convertor.. you may want to switch to a different model like the PAC OEM-1 that allows voltage adjustment for each channel at the LOC module, as well as an actual Remote trigger.
If your amp is using the auto-on power sensing, that'd cause this problem as well.. and you'll need to wire the actual remote trigger line to the head unit's power antenna, remote trigger, or an ignition lead for a 12 volt trigger signal when the car or radio is turned on.

only other cause for this is if one of your RCA cables got pinned or pinched.. replace the RCA lines, even temprarily with ones right from the LOC to the amp, and see if the problem stops.
