You could have the subs wired in the wrong ohm. It might be turning off the amp and check to make sure that you rca cables from the head unit to the amp are connected right.

My sub keeps cutting in and out, it sometimes works than cuts out or I will start the car and it works and when I turn it back on again doesn't.


Your amp may be going into protection or you might have a loose connection. Start with your ground wire to make sure it's a good ground. The check all the other wiring. Hope this helps.

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.

No power to amp.....all wire connected properly


is protection light coming on when sub is connected? some radios have weak remote that blow out easy..check power on it if power is making it to amp..if its an ANL fuse they can look good but be bad.

The main problem I have having is I am getting power to my AMP but no power to the subs. I tested my AMP and subs in another car and everything worked so I know my hardware all works fine. I had someome...


okay , well you need to make sure all your conections are in the right spots, and that your IN LINE FUSE, between your amp and battery, the big glass one is not burnt, just take a look at the metal piece inside , if its a sold metal piece its good, if its burnt in half like a broken bridge it needs to be replaced. the next thing is the fuse on your amp, you need to make sure it is not burnt also. Check your remote that it is hooked up to the right wire. then check that your sub/speaker wires are connected properly and secure. YOUR GROUND WIRE IS HUGE HERE also. MAKE SURE IT IS GROUNDED TO A GOOD SPOT, YOU MAY HAVE TO MOVE IT AROUND A FEW TIMES TO FIND A GOOD GROUND!!!! if you check all of these things, it should work fine.. you can fiddle with your amp and bass settings levels. turn em up so when it works you know it, but not too much you dont wanna blow nothing :)

My amp keeps going into protect


do you have the right size ground wire, relative to your power wire? If your ground is smaller when you turn it up there is alot of power it needs an exit and if the wire is too small it travels elsewhere maybe your rca, causing your amp to protect.

Basicly my speakers were working fine, my subs were working fine but everytime i was turning my volume up to a certain level i would lose all base and all noise from the subs in my boot, so i turned it...


The amp should always light up showing you that it is powered and there will also be a red light that will light up if theres something wrong.Sounds like maybe the hot wire that goes to the amp isnt big enough to give the amp enough power.Check your positive wire and ground wire for tightness and make sure hot wire supply is big enough and also the ground wire is big enough and has a good ground.I hope this Helps you.Have A great day..

Memphis PR300.2 Amp protect light on


If it is not turning on your problem is it is not getting power. Check your fuses. The reason an amp goes into protect mode is usually because the subs are not wired up right. Make sure your fuses are good, you have a good ground, and make sure your amp turn on wire didn't come loose when you were putting the deck back in. As for the amp going into protect you probably wired the subs down to too few ohms and the amp you have can't handle it. Try hooking the subs up straight w/o bridgeing them and turn it up to see if it works. If you don't have problems with it then you wired your subs wrong.

My kicker 10'' L7 sub works when the volume is low, when the volume is turned up the sub. stops working. Why?


Check wires that go into the speaker.Try turning the bass down than turn the volume up.If it sounds good when volumes down and as you turn it up it gets worse your amp isnt putting out enough power.whats the amp? power wire gauge should be same as ground.what gauge are they? Check ground to make shure you are getting a good connection & power wire isn't loose at any of the connection what size fuse are you running under the hood?
