Question about Koiiler XM-6666W Car Audio Amplifier

1 Answer

Sub is getting no sound

My sub is not hitting when I play a cd or radio. My power lite is green, and the remote is working fine. I'm grounded correctly. I'm getting no sound from my deck to my sub. When I turn my car off I can hear the sub go "boom" like it has power. I think it has to do with the preamp outputs or my RCA wires, I'm not sure. Any suggestions?

Sounds like you answered your own question when you said you were getting no sound from your deck to your sub.

Everything works fine but i cant get any sound out of my amp/subwoofer please help spent alot of cash on amp and sub and i want bass!!!


Check the fuse on the main power wire.

Make sure you have a remote turn on wire ran from the radio (blue/white wire).

Make your own ground for the amp using self taping screws....DO NOT USE SEAT BELT BOLTS

I have a power acoustik bamf 1600/4. not working 5 hours later


use a multimeter to see if the amp has good power wire and remote turn on voltage. then check the ground and make sure its a good strong ground. check the sub to make sure its not bad. make sure it reads whatever ohm its supposed to. anything less than 4 ohms will clip the amp if bridged. if alll that is good then the only thing left is the amp. it sounds like the power supply is bad but check everything else just to make sure. good luck.

Radio plays but plug in the rc jacks for the amp and subs and get this grounded out sound plug in different deck works perfect the deck worked fine a week ago


check for loose connections at your speakers and sub. If you have a loose connection, they can ground the other out... look closely for loose strands that may short it out. most of the amps have overload protection and cut out when there's a short/ground out issue..

I had this happen on my sub and it acted like the whole system was cutting out.

Only door speakers have sound on the cd mode


the amp requires a 12 volt power constant, and a 12 volt "on" signal. you prolly have the 12 v "on" hooked up to the car stereo's antennae remote, meaning your amp gets power when the radio is on, cuase the radio is sending a signal to the amp (thinking that it is sending a signal to the antennae to raise)

you do have one of those collapsable antennas, right?

CDA 9885 No idea why it suddenly stopped working


It sounds like you have a bad ground connection. You need to take the radio out and check all the connections. I bet you have a loose one somewhere. That is what the problem was with my bronco

My amp only powers the subwoofer when the radio is on but wont when the cd player is on


The person(s) who hooked up your system made a boo boo. They wired your remote turn on lead to the power antenna lead instead of the amp turn on line (both are blue and easy to mix up). Thus when your radio is on it sends a signal to the amp and the amp turns on, but when you set to CD the signal goes away and your amp shuts down. Easy fix, just re-wire the amp turn on lead and the problem will be fixed.

Kicker 750.1 Amp wont play music


it is probably the rca inputs on the amp may have fried. was your cd decked turned up loudly before the power went out? did any wires accidently touch each other? If had worked fine and then suddenly stopped, than either a wire came loose or the inputs fried. try using different cables and I also suggest disconnecting power for 24 hours and then reconnect. If the green light is on then it is getting power and the problem is in the rca cables or the inputs

Rampage BA-100 200W amplified subwoofer


Actually. I don't think you have to wire a remote switch from the radio to the amp on this product. This powered subwoofer supposedly has automatic signal sensing turn-on circuitry. I have the same problem. So I think I'll try to just hook up the power (to the battery), ground and the + / - speaker wires to one of the back speakers in the car and see if that works.
