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.

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. ;)

I TAKE IT THAT YOU ARE REQUESTING A SOURCE FOR A PAIR OF ENDCAPS FOR YOUR PUNCH-200IX. IF THIS IS THE CASE, I SUGGEST THAT YOU CHECK EBAY ON A WEEKLY BASIS AS I AM SURE AFTER SOME TIME, YOU WILL SEE A PAIR LISTED. THERE IS ALSO A SELLER ON EBAY THAT HAS MANY OF THE LOGOS FOR THE MANY DIFFERENT MODELS THAT CAN BE PLACED ON ANY OTHER MODEL ENDCAPS FROM THE SAME SERIES (DSM, IX, X2, ETC. LET ME KNOW IF I MISUNDERSTOOD YOUR REQUEST......V

Hi my names Josh. I see you want put your rockford amp in. Assuming you have your factory radio you have some wiring to do. But first you need and amp kit it wil have the necessary wiring you will need in it to wire your amp to your car. You will also need a line level converter they you can pick on up at best buy other wise known as a pac converter. This will alow you to transfer the high level frenquency your radio puts out to a low level frenquency to go strait to your amp through a pair of RCA's thus giving you sound to your amp and then to the sub. Your wiring will consist of the ground which you will have to ground off the vehicles chasis no more than a foot from your amps designated location. Then you have you power 12v which is about a 4 gauge wire and will be fuzed and ran strait to the positive side of your battery and last will be your remote wire. Your amp will have a place marked remote on it that is strickly for you to wire to your radio/ignition source for powering the amp up when radio is on and powering it down when it is off. YOU MUST ISOLATE THAT WIRE with a 12 volt tester it will be the wire that is tied in to your radio to power only when your igniton is on and when you turn your key it should tell you if you know how to properly check for this wire. wants you istolate this wire you will want to tie into to it and then of coarse run it and tie it into your amps remote power again it will be marked remote on your amp. From there all you have left is tying in your line level convererter.. This takes some patience as you must make sure that you do isolate your sound left and right postive and negetive front and rear channels the line level converter will tie into either your front or rear channel but caution you dont get them mixed or you will not have a signal at all. Again my names Josh and i hope you are able to get it hooked up okay.
