Amp turns on but doesnt power my subs

Ok the p3001 turns on, it powers the speakers but it is VERY low, i have to turn it up ALOT just to hear a little thump, when i first got the amp it wasnt like this is played fine, after a while it just did that by itself, i have another amp hooked up to another set up 12s and that amp works fine, its just the rockford thats acting this way, i checked all the connections, re wired my subs, everything, is it something internal? and is it fixable?

I just installed a new xo vision x349nt dvd receiver in my car . My rockford fosgate p3001 amp turns on but the subs doesnt come on but when i would take the base control out and put it back in i can hear...

Make sure and check the RCA wires in the back of your radio that send audio to the amp and make sure that they're connected to the OUTPUT/SUBS RCA's and not an input rca's. Also, check your ground and make sure no speaker wires in the subs are shorted. Try one speaker at a time see if that helps.

My subwoofer doesn't receive power, all amp fuses are fine, amp powers on, remote wire and rca wires are connected and intact. Before it stopped working all together the woofer would cut out and after...

If you are getting power to the amp, try this....Find a small speaker, unhook your sub and wire speaker to amp. Turn on your system at a low volume....If the other speaker is playing through amp, then your sub is shot.....If the small speaker doesnt work, then its either your channel is gone on the amp or the rcas have quit off off your head unit.

How do I hook up one sub to my rockford fosgate p3001 amp

Hey i have looked over many rockford manuals,(i own a 300.1 my buddy owns a 325.1) and for there mono(.1) amps there hooked together on the inside so channel A+ and B + are cencted on the inside the amp. So you ither hook one 2ohm sub to channel A or you can hook 1 4ohm subs to channel A and 1 4ohm sub to channel B. There 2ohm stable so any lower will eventualy burn the amp out.

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.

try running the system with a cross-over configuration.

So your left + will be left + and your right + will be in the right + but put the right (-) where the left (-) is and left (-) where the right (-) is. If that doesnt work, then that means that you shorted out your audio out channels. the only way you can fix that is if you have good soldering skills. But other than that I'de say scrap it, unless you have the high outputs and then buy another amp, some mids and highs and connect the mids and highs to the xplod

Stuck On Thermal Mode.

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 is below ~11 volts, you need to check the wiring feeding whichever line is too low.

If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still remains in thermal protection, the amplifier likely has an internal fault and will need to be repaired.

Legacy LA1020 Low Sound, No Bass

have you checked the amp? there should be a switch on it to alow you to change the input of the power, it could be that this is on very low, causing not alot of noise and base to be produced. it could also be the remote lead to your head unit or that it isnt earthed in the best of places. if the amp power is on then you can probably say its not the earth, try checking over the amp for a switch to turn up the input, if not check the user manual and look for amp settings.

cheers, adam
