I have power to my Rockford Fosgate Power 1501BD amp and the led light is on but i dont have power to my subs what can i do to fix this ive tried bridgeing and not brigding the wires but it still doesnt work.
Check the signal from your RCA'S Your head unit may not be putting any output out of the rca jacks on the rear. Or you could have a bad set out. As long as your voltages are right on your positive terminal and remote and you have signal the only other reason your amp will not have any output is if the internals are bad.

The unit is internally grounded. Something has broken inside and grounding out the power, the amp will need to be serviced or trashed. Try calling Fosgate. They may have a serviceman or "fix it" department
Your friend has damaged his amp. The power light coming on means that the amp's power indicator LED is at least working. That light is only there to tell you that the amp is receiving power on it's 12 volt rails, not that it's necessarily using the power in any way other than warming up the amp's internal circuitry. When you say the amp gets power, I'm not clear on whether you mean the amp works in that fashion, or there's just a red LED glowing but nothing else happens. The amp needs to be repaired, and I would suggest to him to not apply power to it again until it is checked by a professional. The power supply has probably been damaged, and it's possible, depending on how the amp was mounted, that it was searching for ground through the amp's chassis if it was screwed into metal at its mounting location. All that seems certain as of now is that the LED works, but nothing else, unfortunately.
Check you inputs to verify you have a signal coming in, if signal then check outputs try a speaker that you know is working and plug it in if that speaker plays then the subs/ or speaker wiring is bad, if it doens't play then you probably have a blown output transistor on the amp or possibly a terminal ground/positive has come loose on the inside..
un hook the subs and let the amp sit there on if the protect light shuts off you wired your subs wrong if it doesnt go off tun it off then back on with no sub music all the way down then slowly turn the music up if the light is off then comes on you need new rcas
Power caps store power from the battery and they feed constant power to the amp so you dont get no drainage! this could be one reason..
have you bridged both subs and wat gauge wire are you using.
these amps can only handle one bridged sub at 4ohms and this amp is recommended that u use 8gauge or higher. if your running to subs i normally reccomend using 4 gauge power wire as you get more rms power feed to the amp
you can get a power cap or anyother accersory cheap online at my suppliers.. caraudiosecurity << click to enter >> hope this helps and please rate me :)
Send me your email account and i will draw you a diagram and send it to you there. I will need to know if the ohms of each sub as well as the amp. I'll also need to know if the subs come with one or two voice coils.
send the rockford to landis technical-they bought up all the parts to rockfords amps and will get them back to factory specs and recertify it for ya along with a new power certificate-look on rockfords website and snoop around and it will break it on down for ya and give you the address n stuff. i had to send my 1501bd mono amp in to get an overhaul and it came back throwin 1810watts rms so that was better than when i started -good luck.
