OK question # 1...I have 2 COMP vr subwoofers 2 ohm dual voice coil 400 RMS in a dual 12" enclosure

would these be the proper type of amps to looks for

1) 2-channel 400 RMS @ 2 ohms

2) Monoblock 800 RMS @ 4 ohms




ALSO when these subs were 400 RMS each, but when loaded into a box the guy told me they are now 300RMS each for a total of 600 RMS...why is that:S

 

your options for those subs are 2 ohm, and 0.5 ohm... BTW...

so i wud need a an amp that puts out

400 watts x 2 @ 2 ohms
800 watts x 1 @ 2 ohms?

either of these two?

 

sure, either of those 2 options would work out well, from a power standpoint at least..

Mark

 

Actually the second option works better....your drivers can be wired to either 4ohm or 1ohm per driver, so the first amp would have to do 400 X 2 at 1 or 4ohms for the same power per driver....

Much harder to find an amp that does 800wrms @ 4ohms X 1....they are out there, but the variety of 800 - 1,000wrms @ 1ohm mono amps helps keep the prices down....
