bridging a 4channel to 1 or sending 2 channels of power to one mono source?
I have an MRV-F400 4/3/2 Channel Power Amplifier
I want to know if it can be bridged down to 1 channel to run a pair of jl w3 d4's in a enclosed box - if so how and what would it's power output be? The jl's want 200 and up watts at 4 ohms each. according to jl's chart. If this amp can't do this is there a way use it in two channel mode but send both to the one speaker box? if so how, and how much power would they get then? eventually soon I will get another amp but I can picked up 2 10's in a box on clearance at myer for 240$ and the ported 12 I wasusing has been Driving me crazy.

"SmilingSinner" wrote: "You've messed up the amp specs" Those are ccp'd from the manual I'm sure it doesn't say "Per Channel into 4 W". That should be "Per Channel into 4 Ohms" or "Per Channel into 4 ‡". (Not sure if omega symbol "‡" will translate charsets.) I realise it will bridge down to two channels at 160 each though not 100 - but is there no way to send both channels power to one input through a y connector or something? No, and the 160W bridged rating is when the other two amps aren't in use. It's a 200W amplifier. "Kevin McMurtrie" wrote in message ... You can only bridge two unbalanced amplifiers into one balanced amplifier. If you bridge all 4 channels in your amp, you end up with 2 channels. You've messed up the amp specs a bit, but I think it says the maximum power into two 4 Ohm speakers is 100W each for a total of 200W. It's a 200W amplifier and no trick is going to change that.
