I have had a pioneer 800 watt amp hooked up to 2 10in rockford fosgate P1'S for severall months now. They worked fine up until I added 4 interior punch speakers and a 1.6 farad capacitor. When the car is running and the cd player is off the cap reads 12.2 when the cd player is on the cap reads "lo." I'm puzzled i checked all my connections and the seam fine all of a sudden it just stopped working.
You need to run a larger power/ground cable. If you are reading low, you are not getting the kind of voltage that the amplifier requires to run, you may have been fine before adding the other products but if you wired them all to the same power wire (say an 8 gauge) you'd encounter problems. You should probably use a 2 gauge or at least a 4 gauge power kit.

dual voice coil subs hook up mono on amp, from amp - from right side + from left side of amp run to sub n then jumper wires from one side of sub to the other side goes negative jumps on positive and positive jumps on negative
Is it the correct size fuse ? Is it the power fuse or remote ? Either way check your connections going into the amp . Try this hook your other amp to the set of wires for the rockford if that amp has a problem its a wireing problem if not chances are its an interal problem on the rockford . Hope this helps !
First are they in the same box? If so and they are sharing the same air space running one amp to both is best andwill perform better. One woofer could be over powering the other and or you could have a woofer problem. A lso your wiring coul be problem. When amp is bridged it changes the OHM reading and output your other woofer may not be rated at or able to handle a lower Ohm rating also it coul blow that woofer if it hasn't already hapened . Be careful. check woofers independently for operation and check the non performing woofer on an unbridged power source or amp. Hope this helps. Write back if not.
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.
sounds like the sub that throws it into protect mode is cross wired pull sub out and make sure they are wired right make sure ground from sub goes to ground on box and do same for power wire
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.
Have you noticed any other circumstances that cause the cap to read 'lo'?
Do you have a multimeter to check actual voltage at the cap?
With CD off.
With CD on.
Is it a dedicated line going from the battery to the capacitor and amp? Just the cap, the amp and nothing else?
Does the CD player otherwise function correctly?
