You have the amp connected to the blue wire on the radio instead of the blue one with the white stripe. The blue one is the power antenna wire so when you switch to cd, it would close a power antenna. If you dont have a blue /white wire, you can hook it to the red 12v wire. Good Luck

My ph5000d plays until i turn it up then it cuts in and plays then to protect mode back on why dose it do that its just when i turn radio up


Ok because your wattage is too high for the amp when adjusting a amp with speakers always start like this turn amp gain all the way down head unit bass all the way down and treb all the way up then turn on ur highest listening volume that u like then ajust amp to that hight if will stop protect from happening if continues ur sub is too many watts for amp ok

Fai-3a installed, subs work speakers dont


did you cut them and splice into them. Because instead splice them all together and it should all work. or if you have a multichannel amp just hook ur factories into the amp as well.

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.

You're using the wrong control wire. You're likely using a wire marked antenna control. You need to use the one marked amp control. They are both blue.

AMP FOR SUB SHUTS OFF SOMETIMES


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.

LED Light is on, but no sound from sub at all.. Have double backed on all wires but still nothing! HELP!!


If you've overheated it a number of times, it's possible that you've damaged the amp and it's trying to protect itself even though it's too late. Try disconnecting the sub from the amp. If there's no change, then there's a problem within the amp. It could be a thermal switch or possibly a stressed amplifier module.

Hope this helps. Good Luck!!

Alpine mrp-m650 amp cutting out


Some AMPs have a thermal cutout, that switches the amp off if it gets too HOT.

But this sounds like your amp or sub is screwed, either there is to much resistance in your sub, eg: Burnt voice coil, carbon builds up on the coil stopping the sub from moving freely. Push on the cone of the sub & listen for a scrapeing sound.
or test this by continuity testing the sub terminals & pushing the cone if the BUZZER on the MultiMeter cuts in & out as you push & release then your sub is screwed. ( a certain amount of repeatative pushing it may free up the voice coil.)

or your Amp may have blown a internal fault that will have to be sent of for repair.

Or you have a incorrectly rated fuse for your system,

or the battery cant kope with the power surges???
THIS DOES NOT APPLY TO YOU AS YOU HAVE A POWER-CAP!!!

My amp turns on then the music cuts in and out


check your main ground, if possible try to read voltage across making sure 12-14v present with load and some signal.

No bass at higher volume


Your battery should be fine! Although the amp might not be strong enough for the sub. All you can do is check the RCA cables from your radio to your amp as these might vibrate loose when you get to 17 volume and also check the monster cable from your amp to your sub asit might have vibrated loose as well.
