I have a Alpine V12 MRV-T500 bridged to 1 chnl 200W 4ohms for Sub
and a Alpine V12 MRV-F250 4ohm 4chnls to rear & front components.
I am currently running 8 Gauge power and ground wires to the amps, directly from the battery. Im wondering is this enough or should I upgrade to 4 Gauge?, is it going to make a difference?

cheers,
JaBZ
