    the red light is on the amp but the woofers will not play. At one time they kept going off and on. When the woofers came off and on the red light would blink and it would cut back off.

Smae as my cd player when its turned up over 40 volume the amp stops and the subs also
what it is just lacking power from the battery bacuse the altinator does not keep up you may need a capacitator or a dry cell battery that takes no water there called odyssey or stinger or pulse now if your amp wont turn on check the fuse for the positive and check the amp fuse check all connections are still good and the remote wire.
also make sure your using good gauge wire,
if still not working you my have over heated the amp and bang bang bew it up?

The reason it used to cut-off at 60% volume as you said before,
Is probably due to the "protection circuit mode" being tripped.

You can try resetting it by turning off your CD player ,removing the Batt( + ) and Gnd ( - ) terminals from the amp for a short period. Reconnect them Allow the amp to receive power but not switch on (keep cd player/remote power source off)

If you dont know how to wire the CD player to control the amps power status , the easiest way is to connect the 'power antenna' or similar low voltage throughput wire from the head-unit to the amp's Remote terminal.

My old amp did the same thing ,and would need to be powered off/on before resuming sound output, sometimes I had lots of trouble with the protect mode staying on , even with little or no sound output from headunit.

Sounds like an over current condition. Your sub may be the problem. Does it go into protect mode when it cuts out? remove the sub and turn up the volume and see if it cuts out when you keep increasing the volume. If not, then it may be that the sub shorts out when turned up too much, kicking the amp into protect mode. If it still cuts out, then it may be the amp. Try another sub if you have one or borrow one from a friend.

Bass cut off when volume is too high


When an amplifier shuts the Bass off that means its going into protection mode otherwise it will burn out the outputs. One way is to turn your gains down, Pioneer amps are not the best amps for bass out there, they are more for car speakers, I personally wont use a pioneer amp to run my subwoofers especially if they are hard driven subs like JL , Kicker Solo's and MTX subs. But for now just turn the gains down to 3/4 and that should help u, you can also install a fan to keep your amp cooler, if this never happened before in 5 yrs and now it does then that means your amp is just tired and the inside components are overheating easily, thats common with Pioneer and Sony amps.

Good luck buddy.

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.

1000 w sony xplode works at low volume then red lights at volume5


Most likely one of your subs are blown, or the Ohm's are too low for the ampliphier. Try hooking up one speaker at a time to the amp and see if it does the same thing. If it shuts off on one of the two speakers, that speaker is most likely blown.

Amp does not power on, flickers when cable disconnected.


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

You are most likey running too much power from the amp to the speakers.. you might want to try just notching the bass down a notch or 2.. just enough that the bass will hit
