brandonlearL7 Posted June 21, 2012 Report Share Posted June 21, 2012 I have never done the big three and I use 4 gauge wire. Do you have a capacitor?

HHR Ed Posted June 21, 2012 Report Share Posted June 21, 2012 1500w is right on the upper edge of a stock batt setup. Id suggest to just upgrade that battery and beef up your wiring. Wire gauge depends on how long you run it. To get a real 1500w, 4awg run from front to back is too small. 2awg will work, but 0awg will give you head room up to 2000w Ed Lester ShowtimeSPL Host Showtime Electronics Video MarketingMy old Build Loghttp://www.stevemead...08/#entry511451http://www.youtube.com/showtimespl 5 time dB Drag Finalist Last ride 2007 HHR, current dB 153.5 and bass race 149.4 dB. 153.0 dB on music New Ride, 2008 HHR SS.

ROLEXrifleman Posted June 21, 2012 Report Share Posted June 21, 2012 Just do 0. The price difference is cheap peace of mind if you ever upgarde anything else. Amd to much is better than not enough. What kind of amp draw is your amplifier pulling? That will be a greater factor on what upgrades, other that the 0 gauge, you will need. Rolex you sicken me.

Rockbrook Posted June 21, 2012 Report Share Posted June 21, 2012 if you can afford to upgrade to bigger battery you should, if you can afford the 0 gauge do it, it'll be ran for when you decide to upgrade. I couldnt afford it, im running 4 gauge to stock battery, no light dimming issues really neither. Link to comment Share on other sites More sharing options...
Gotta_LOVE_BASS Posted June 21, 2012 Report Share Posted June 21, 2012 4 or 0 would work iv been down the same path and brandonlearL7 GET RID OF THE CAP THEY ARE CRAP they r just another thing to drain power from the battery personally i would go with 0 gauge more room to grow but also agree with HHR Be Happy With What You Got Link to comment Share on other sites More sharing options...

Tim Lam Posted July 14, 2012 Report Share Posted July 14, 2012 do the big three with 0 awg. keep your stock alt. upgrade the battery under the hood. (might i suggest a Kinetik HC1800?) and look at the inputs on the amp and just use the gauge of wire it says can fit (0awg is almost always preferred over 4awg) Link to comment Share on other sites More sharing options...
siucsaluki11 Posted July 14, 2012 Report Share Posted July 14, 2012 Just run 0 ga and call it good. Im running 0ga to the trunk, HC1400 under the hood, no big 3 (yet) no 2nd batt, stock alt, BRZ1700 at 2 ohms and MRP-F300 at 4 ohms, voltage drops to 12.9 at full tilt while idling. Doing big 3 in a few weeks, hopefully it will stay a bit higher after that. woman..cant live with em...cant shoot em...guess were all fucked You might be a Redneck if you use your leftover gutters for a speaker box port...
