There is no reset button on the amp.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) 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 is below ~11 volts, you need to check the wiring feeding whichever line is too low. If both are above 12v, the amp will require servicing.

Bridging two12" subs and one 15" sub to my Rockford fosgate T 1500bd amp


assuming all 3 subs are 3-4 ohms, running all 3 in parallel (the 3 positive leads all attach to the amp positive terminal, and all 3 speaker negative leads connect to the amp negative terminal) will bring you at or above 1 ohm, which the amp is capable of handling. With 1500 watts, you will want to use 8 gague power leads for the amp, 12 gague speaker cables, and an inline 120 amp fuse between the amp and the battery, within 1 foot of the battery.

I have a rockford fosgate punch P325.1 subwoofer mono amp that blows a fuse every time i start the car. I have a second pioneer amp but that works with no problems. How can i fix this?


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 !

Rockford Fosgate Punch P325.1 Amp keeps blowing fuses every time I start the car. What is going on?


well if the amp works with the car off and when you start it the fuse blows then you may have alternator issues use a volt meter to check battery voltage is not above 14.5 volts
if the fuse blows when the amp turns on then most likely you have a shorted output section in the amp.

I have a rockford fosgate 550 that the fuse blows


Short inside one of the transistors. This requires very good soldring skills and electrical know-how, and some thermal paste to go between the heat-sink and the transistor. Unfortunatly this is not a cheap repair, probably cost around 100 dollars.

Cheers,

Kevin

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.

There is no reset button. If you disconnect all of the speaker wires from the amplifier's speaker terminals and unplug the RCA cables, does the protect light still come on (I assume that you've already replaced the fuse)?

Rockford fosgate rfx-9200


If you're talking about the amplifier's power terminals, the positive terminal is designed to be wired directly to the battery (be sure to fuse the amp power wire near the battery terminal). The negative terminal should be bolted to vehicle chassis metal for a ground connection. The only amplifier connections that go to the back of the head unit are the remote turn-on wire and the RCA cables.
