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.

When I connect all terminals to my amp the led light won’t come on.. i had gain 1/2 wat was at 80 hz on low pass radio volume was 20 out of 50 so not loud... was hitting my 2 12” 2000 pioneer premier subs they were moving normal all run to 2ohm and it just stopped working won’t light up .... no bad smell from amp or subs anyone have this issue before or how to fix
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
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.
