SOURCE: Rockford fosgate 800 a2 amp power?

Hello desperate2le,

Watts delivered is a function of the voltage times the current. If the amp was 100 percent efficient, it would need 33 amps at 12V for 400 watts. At 14.4V, it would only need 28 amps. Of course, amplifiers are NOT 100 percent efficient, only about 50-60 percent in many cases, but somewhat higher for monoblocks, maybe 80-90 percent. So you're looking at a fuse in the 60-80A range. In the absense of a specific fuse size from the manufacturer, I'd start the primary fuse at a 60A and if the amp blows it on power up/immediately/frequently, move up to an 80A.

All of the Rockford-Fosgate 2-channel bridgeables I've ever seen show using the left positive (+) and the right negative (-) for bridging. But if it's not shown right on the amp, I'd call or email RF for the correct connection. The new amps do show it.

Hope this helps.

SOURCE: rockford fosgate 3002 thermal light on no sound

Is this powering speakers or subwoofer? If it's the subwoofer you need to make sure the gain is turned up and the sub is set to low pass frequency. Also make sure bass and subwoofer are enabled on the head deck. Make sure the RCA's are hooked up properly at the back of the head deck. If it's the speakers then you may have balance set to front only so your rear speakers aren't making noise.

SOURCE: 401s Rockford Fosgate Amp. Not powering on,just protect lite is on.

the problem is mostly with your audio side of the amp. i have a 800 Rockford punch series amp hooked in series running at about 15 vdc at 2 ohms stable for now. but the amps left front power side transistors overloaded and smoked out, i will be replaceing my mosfets soon. Now on that side your issues apear to be related to the signal side of the amp. when you hooked the amp up tell me breifly did you hook the rca inputs to the back of the sterio and did you select the proper rca inputs for the amp? also note that amps have a potentiomater that can be tuned up or down to allow the volume or wattage to go up or down threw the system. if it's turned all the way down you'll here nothing. but often you'll get a pop sound or quickly see the speaker move a bit. this indicated the signal side of the amp has signal comming in but no output, just look for a turnable small screw inside the amp top or side. and turn up acordingly. note: to much output will damadge your system. not just the amp. ;)

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..

I get a better sound with my 250.2 than with my 500a2

Rockford Fosgate was bought out over 10 years ago. the amps you have are from that era. Its probable that the 250.2 was made before the change over, and is just a better quality amp. the a series amplifiers were some of the first produced by the "new" Rockford Fosgate, and they sucked, along with most of their products since.
