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.
Thanx for any and all help
here are the amp specs
