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.

Ok.. Bridge the two sub into 4ohm than bridge to amp.
So. this how it goes.
sub1 + -
to | |
sub2 - +
= 4ohm
From Sub
Two
- +
| |
amp (L) - + (R)- +
This will use the full potiental of RF 800a2 amp. I believe it like 1153 watts max out.

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
