Been considering the big 3 upgrade for a while, recently looking at my voltages. With the cd player off + engine on I get 13.6V, with the car off I get 12.2V (once I play music obviously these values change). I have some 2g wire lying around so I'm considering getting some terminals and wiring it up but on such a low power system I don't know how much of an improvement I'd see.
I have 180WRMS (4 ohms) on speakers, and 350WRMS (2 ohms) on the sub, each amp using 8g wires to the battery. The car has a 50A alternator and the stock wires consist of:
-ve battery to starter motor + chassis - 7g (looks slightly thicker than 8g) about 85cm worth (33.4645")
+ve battery to alternator - 7g about 50cm (19.6850")
motor gnd to chassis - 10g about 30cm worth (11.8110")
By replacing those 3 with 2g will I really see my voltages rise much? or does that generally apply to higher powered systems?
Cheers.
