KMS Posted July 6, 2011 Report Share Posted July 6, 2011 Wondering if a 80alt amp on a 4gauge power wire would be enough to handle 800rms for a sub, and about 125rms-X4 for mids and high (does that even matter?) I don't notice any kind of dimming as of now on a crescendo 1000c4. I have channels 3/4 bridged for the sub at 500rms. Then channels 1/2 have 4 speakers wired into them,so I'm guessing it's seeing a 2ohm load. 250w x4 channels at 2 ohms. Would it be better to get a 120amp alt from a GTI? or a HC800 from kinetic, Alpine PDX-V9 Morel Tempo 6 Alpine SBR-S8-4 Alpine CDE 149BT Link to comment Share on other sites More sharing options...
bokeson Posted July 6, 2011 Report Share Posted July 6, 2011 I'd do the big three in either 4ga. or 1/0ga just to help your electrical a little. not needed but I would do it if I were you Link to comment Share on other sites More sharing options...
