kweezinarts Posted May 1, 2011 Report Share Posted May 1, 2011 the guy at my local stereo shop said that at their training sessions they were told only to double the size of your existing stock 3 and that the 0 guage Big 3 could be bad and fry something in your fuse box. He told me to do my Big 3 in 4 guage. Just got my Knu KCA 1/0 in today soo... Is there any truth to this? the voltage output of the alt and batt is the same how could this be?

dereileak Posted May 1, 2011 Report Share Posted May 1, 2011 nope, not at all, that guy must be retarded, all the thicker wire does is reduce resistance, and makes it easier for the power to flow through, especially during high loads where the factory wires would rise in resistance due to more current going through them then designed, some cars do have sensors, like a few Toyota that you have to wire it differently though. I will say though he has some truth but not in his sense of thinking. Factory wiring can handle the loads that they alternator was designed for, so if you are doing more then double the size of wire then the factory, it means you are gonna need a new alt someday, ha ha, but all depends on how big your system is Quote 2006 Mazda3 Hatchback Black 5 Spd ManualPioneer 4300DVD2 Sundown SA-12 (34hz Tune, 3.22 cubes, 14.5 inches per cube, Triple Baffle)Kicker 10ZX2500.1 (2845 RMS) Sub AmpKicker 11ZX650.4 (705 RMS) Mid Amp -- (3 Amps)Kicker KQ3 Active CrossoverKicker KQ30 EqualizerKicker 09QS60.2 Components (Woven Carbon Cones)Kicker 09QS65.2 Components (Woven Carbon Cones) - (3 Sets)2/0 Gauge Electron Beam Technologies (3 Runs, 2 +, 1 -) 1/0 Gauge KNU Kollasal Flex (1 Run for -) 300 Ft Kicker X-Series 16 Gauge Speaker WireXS Power D3400 (Rear)XS Power D3100 (Front)Singer Externally Regulated Alternator (Being Built)+ The Love for Car Audio and BASS <3UBL Build Log <------- Click Here-------> Normal Build Log (For Comments) Link to comment Share on other sites More sharing options...
08tahoe Posted May 1, 2011 Report Share Posted May 1, 2011 the guy at my local shop told me to use 4 gauge also cause it was better for some reason but i didnt listen to him and still did mine in 1/0 gauge Quote Link to comment Share on other sites More sharing options...
AMI CUSTOMS Posted May 1, 2011 Report Share Posted May 1, 2011 I would like for you to ask him how it would fry something,"anything" in the fuse by making the wire larger for the Big 3. And then post his response here.
