I don't think you can. The model you have would help a lot. Depending on the model you can some times bridge a 4 into 2 but I don't think 1 channel is possible. On the older models there is a plastic plug on the bottom that can be removed and there was a switch under it for changing the outputs.

If the wires were touching then the amp overworked itself into a early grave..What happends when they touch is the amp goes from seeing a 4 ohm load to seeing a 0 ohm load. You can imagine why this would be bad for a amp...usually the amp should shut off to protect from damage and I would assume that Rockford would. Right now im having a similar problem..I suggest your call rockford and ask to talk to a technical advisor ( the name escapes me) and ask him what he thinks.

never attemp to bridge your amps specially this type of amps. this are too very complicated. you may blow your amp if you will attempt it again.

If the speaker is a 4 ohm DVC (two 4 ohm coils), you can't wire it to get a single 4 ohm load. Try connecting one coil to each of the two rear channels. It may not be as loud but the amp should operate without going into protection.

If the two 4 ohm coils are in parallel, the amp is driving a 2 ohm mono load. That's probably why it's shutting down.

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.

What would cause 1 channel of a Rockford Fosgate T800.4ad 4 channel Amp to fry speakers while there are no such problems with the other 3 channels?


Question: what starts to smoke, the speaker or the amp? I'm assuming it's the amp. It cant be a fuse because that's what fuses are for to cut the power on an overload or surge. I would have a look at you circuit board for the amp My guess is what you;ll find is a burnt spot on the board and that will tell you what component is bad and needs replacing. Good Luck

How to bridge a 1 channel 1000 punch 55amp


You can not bridge a 1 channel amp. Bridging is when you combine the output of a bridgeable two channel amp into one channel, typically to power a sub woofer.

I need a schematic for a RF p300-1 amp. Im trying to replace 2 of the mosfet semiconductors that got fried.


There are no schematics for RF amps, normally RF uses standard IRF Mosfets. Can you decribe the area where they blew, Power Supply are usually N-Channel high current type. Outputs can be either N-Ch or P-Ch depending on the Power rail there attached to.

    • 2 ch: (4 Ohm) 100Wx2
    • 2 ch: (2 Ohm) 200Wx2
    • 1 ch: (4 Ohm) 400Wx1
  • Maximum Power (EIAJ)
    • 2 ch: (4 Ohm) 250Wx2
    • 1 ch: (4 Ohm) 750Wx1
  • Frequency Response: 10Hz - 50kHz (0,-1dB)
  • Total Harmonic Distortion: <0.01% (1kHz, 4 Ohm)

How can i bridge a mtx 9500 using a mono amp?


You cant bridge it to the MONO AMP . You can only bridge subs & speakers to 2 CH & 4 CH AMPS that are bridgeable. Because if it appears that there is 2 channels on a Mono amp its so its convenient for you to hook up 2 4ohm subs to it easily But both channels are actually connect internally together in parallel inside the amp unlike a 2 channel they are separate.

So just connect your mtx 9500 to a plus and a minus and doesnt matter which since all the + terminals of are connected together and - are connected together already.

Whats important is on the side of the sub/box it reads 2 ohms. The lower the ohms the more power the Mono amp will put out. Mono amps are designed to handle 2ohm loads.

If it reads 4ohms The MONO amp is the wrong amp to use cause the power will be weaker. So if you have a 1000 Watt Mono amp at 4ohms the sub will only get 500 WATTS Max while a 2 ohm will get the full 1000 Watts.

If it reads 4 ohms connect it to a 2CHANNEL AMP and BRIDGE IT (connect + of the sub to 1st channels positive of the amp then connect - of the sub to 2nd channels negative of the amp) . The power will be doubled when you bridge it on a 2 channel amp. NOW if it was a 2 ohm sub and you bridged it to the 2 channel amp it will fry the subs and ruin the amp. 2 CHANNELS CANT TAKE A 2OHM LOAD BRIDGED OK.

How do I hook up one sub to my rockford fosgate p3001 amp


Hey i have looked over many rockford manuals,(i own a 300.1 my buddy owns a 325.1) and for there mono(.1) amps there hooked together on the inside so channel A+ and B + are cencted on the inside the amp. So you ither hook one 2ohm sub to channel A or you can hook 1 4ohm subs to channel A and 1 4ohm sub to channel B. There 2ohm stable so any lower will eventualy burn the amp out.

I have 4/3/2 ch. alpine f-240 amp- i want to hook up four 6x8 3-way and one 12''sub. the amp has bass EQ on ch. 3. how would i hook it up and get the most power. can i put the 4 6x8 bridged all together...


run two 6x8s on each of the front channels of the amp. then depending on the sub you can bridge it on the rear channels.only if its a single four ohm. if its a dual 2 ohm sub run each coil on each channel. 1 coil-1channel. the other coil-the other channel. amp should run fine may run a little hot since it will be doing all it can do at a safe ohm load. just make sure it is mounted in a well vented area. should be safe.

It has an A and B channel for spkrs and i have one spkr bridged. do i split the neg to side a and pos to side b or just use one of the channels?


Could you elaborate on how the speaker is bridged?

I think you want to hook up a single speaker to a stereo speaker output.

In this case, you would strap (bridge?) the right and left speaker terminals by running a short wire from A right negative to A left negative. Then strap A right positive to A left positive -- this will give you mono output on either of the right or left speaker terminals -- connect your speaker to either one of these.

Do you know what the ohm rating is for the speaker outs on the amp and also the speaker itself?

Ccan it be bridged with a 5 ohm subwoofer?


Hello cameron_cran,

The information I found on the amp is that is a 2-channel and is bridgeable. It is stable in bridged mode to 4 ohms. You should be able to bridge a single 4 ohm sub without damage to the amp.

Hope this helps.
