What are the model numbers of the amps and what power cables have you run/how are they distributed?
Cheers.

umm mrpf600...mrpm500....i bought a 4gauge sony wiring kit....and ive run the power cable straight from the battery up the side of the car to a distribution block under the back seat, which splits in 2 and goes to my amps in the back.

Is the 4 guage kit split to 2x8guage wires? The 4 channel needs a 4gauage power cable all to itself. According to the specs the mono can run off an 8guage powe wire, though if you can fit it under the terminal 4guage is the way to go, considering it is putting out 500wrms.

I'd say an upgrade in power wires is needed mate.

I wasn't aware that undersized power wires could cause dimming..

This would definitely be the problem in my VR if it is indeed the case

Not sure mate but i know it wouldnt be helping the situation, but with those amps you shouldnt get much dimming. Either way though - always make sure your power cables are up to the job!

And no, a capacitor will not fix the issue.

a power cap fixed the exact same problem in my car have a read of this...

Capacitors are like band aids in most installs.

theres no 8gauge wire in my install...i got 4gauge going to the distributer...and two 4gauge wires coming out...

Wire the same size as your power wire.
