Help...Weird Loud Bass Noise when deck is "OFF"!
A friend of mine has a 2001 Neon with a single Bandpass Swiss Audio 10 inch sub (300w max) powered by a Kenwood KAC-5201 (250w max).
We switched his box with 2 sealed GNX 124 subs and he loved the sound. We noticed that the amp was turned down all the way, so we bumped it the gain up to half way.
Now here is where it gets really wierd.
He turned his deck "off" by mistake, and a really loud bass noise came from the subs. We turned the amp back down to where it was, and the noice dissappears. What is more wierd is when we have the deck "off" and the amp up, if we walk away from the car, the noise stops, but if we get close, it comes back...and if we actually touch the subs with our fingers, it stops. All this happens when the deck is "off" and the amp turned up just a little over 20%. When it is "on", it sounds great and works perfectly fine.
He only has a factory deck, so he is using a highlevel input from his back speakers.
Does anybody have any idea what is going on?
Ha! I know this one! And it's pretty simple
I haven't read all these super long blogs, cuz I already know and it's quite simple. Maybe It's already been answered for you but your problem is your "remote" wire. I've had this problem in older cars that don't have all the wiring necessary to swap the wiring harness. Esp If you have a higher quality amp that may or may not have some kind of small "capacitor" built into it. If your still having the problem Have someone stand in the back, look at the power light on the amp, kill the motor after playing some music to get some juice. Either the pop (from the sub) will come right away or the light on the amp will slowly fade rather than disappear and once it goes out then the pop will come. This problem also comes if you just hard wire your deck to the battery. I can't tell you the best fix, but if this sounds like your problem, then the easiest way (not sayin it's the best) is rather than hook up your Decks "remote" wire to the internal one (or however you have it hooked up) simply run a wire from the remote on the back of the deck and stuff it into a 15 or 20 amp fuse underneath your steering column. Btw when this works, be sure to spread the word. Oh, And If your remote wire doesn't have a tiny fuse already just splice and throw one of those tiny cylindrical ones on it.
