Question about Koiiler XM-6666W Car Audio Amplifier

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?

I have no sound coming from my sub or my back speakers. all the fuses are fine and all connections are fine as well and the blue light on my amp is on. and the it seem the power light and protection light...

With the radio OFF, take a jumper wire and connect from the 12V input to the remote input of the amp to see if it powers on.(BE CAREFUL NOT TO TOUCH THE GROUND). If it does, your remote from the radio is either cut somewhere, or not working at all. If it doesn't turn on then turn on the radio and do the same thing with the jumper wire, if it turns on, then your 12V power from battery is not working, maybe a blown fuse by the battery?

I have this hooked up and works fine with the key on, but when i start the car, sub light, amp and sub dont come on.

You have connected it to the wrong power wire - one that is only active in service mode - first key position.
You should draw a wire directly from the battery (don't forget to add a 40 amps fuse on the wire) to the amps. If you don't want them constantly operational (you will have to manually shut them down) install a relay on the wire with the command coming from a wire from the instrument key position - second position of the key. Use a voltmeter to identify the wires.

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.

Amp has power but sub doesnt work

You say the amp has power so you mean the green l.e.d. comes on correct? If so and you don't get any juice to your sub, check your RCAs make sure they're hooked up correctly. If they are check the wires to your sub, make sure they're making good contact, if its a binding post connection to the sub it can look connected but not be i've had it happen to me before. If the l.e.d. is red, you either blew a fuse on your amp, or your sub is blown, but if you get a green l.e.d. on the amp don't worry about those. If everything checks out and you still don't get power, take your setup to a professional and have him personally look it over for you....... hope you get your bass bangin!!!

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

your amp may be overheating, or you have it up too loud and the surge protector is shutting it of in fear of damage to your amp.

Amp does not power on, flickers when cable disconnected.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is too low.

hi, your amp seems to be getting power but the cables might be wrong so it's not getting enough power. the light on the amp should be green if everything is going well. are you sure the cables are suitable for your amp?
