How To Do The Big 3: Tutorial


Guest MegaloManiac

Recommended Posts

I had been looking at upgrading the stock wiring on my '00 Protege anyway, it's looking a little rough....

I'm only running a single 10 on ~400w and the lights dim once in a while. Thinking of doing the big 3, but Lowe's is the only place local that has 0 gauge wire (and it's a plus I work there...). Would their wire be good enough?

Also, going from engine to chassis, are you bolting *between* the alt and the engine or just tagging onto a bolt from the alt? Same place with ground to frame? I think I'm already grounded to the strut tower as it is.

Thanks!

ok so i looked through this thread and i didnt see anything about how to do the big 3 if your battery is in the trunk my car doesnt have a battery under the hood so how do i do the big 3

Same way you'd do it normally......follow what UnderLoK said. Only difference being your battery is in the trunk..

  • Best options is FRAME->ALT BOLT (or alt ground if the alt has a bolt on it for that), FRAME->BATT (negative), and then ALT->BATT (positive)
  • Second best is STRUT TOWER->ALT BOLT, STRUT TOWER->BATT (negative), and then ALT->BATT (positive)
  • Third best is CHASSIS->ALT BOLT (or alt ground if the alt has a bolt on it for that), CHASSIS->BATT (negative), and then CHASSIS->BATT (positive)

Step 6 Split wire where required (add ring terminals if needed) and connect the ends to each side of fuse holder.

Step 7 Connect the last end of wire to battery (add ring terminal if needed)

do u have pictures for this? im kinda lost here what do u mean by split the wire? like cut it to length? or split it down the middle into two? and what are those conectors tht u have on the battery?

Ok first things first mixing subs is not good even running different amps the subs will cancel each other out imo..... use the 12s or use the 18" imo.... you need more than one battery what wire running from front to back

Hi SMD Members If anybody has computer problems and is an SMD member with at least 150 posts I will fix your problems for free by phone support or I can also fix your computer over the internet.... I have references such as All State insurance, Nationwide Insurance and much more... just p.m me for help.. I am not the greatest with when it comes to audio systems so I figured I could contribute to the forum this way.... Thanks David
