SOURCE: Rockford Fosgate 800a2 To 2 SVC 2ohm subs

Ok.. Bridge the two sub into 4ohm than bridge to amp.


So. this how it goes.

sub1 + -
to      | |
sub2 - +
=      4ohm
       

           From Sub
                Two
            -          +  
            |           |
amp (L) - + (R)- +


This will use the full potiental of RF 800a2 amp. I believe it like 1153 watts max out.

You should definitely upgrade the power wire to the sub amp to 4 gauge -absolutely your choking your amp its starving for current-poor thing is starving !!!!!!!

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. ;)

Rockford fosgate punch 700s gets very hot


Disconnect the speaker wires from speaker terminals on the amp and turn the amp on (turn the head unit on). Set the volume to zero on the head unit.

Does the amp get hot?

If it does, either the bias is set to high or the amp has other problems. If it does not, you may have the speakers wired to the wrong ohm load.

Quick question, amp problem


make sure you ground wires arent shared, meaning run each ground wire from each amp to its own grounding point

Rockford Fosgate 501bd question


that amp should work fine with those speakers,just make sure that they(speakers)are wired for 2 ohms.at 500-600watts coming from amp, you should be getting 250-300 watts per speaker,just dont crank your gain too high on the amp.
