Kevin M Posted March 13, 2012 Report Share Posted March 13, 2012 Feel free to do what you like. The advice you are getting is solid though and I feel the need to say just because you haven't experienced a problem doesn't mean you don't have a deficiency.

lotus Posted March 13, 2012 Author Report Share Posted March 13, 2012 i know that my amp is probobly not getting enough power but i would just like too know if it is okay to add 4awg big 3 without any 2nd battery and on stock alt. my friend has 2 12 hdc3s on a aq2200 in a custom box tuned to 36hz with the big 3 in 0awg and a xspower3100 2nd batt. and his system only sounds slighty louder than mine. like 3db-5db maybe. and i have stock electrical with 2 xd 12s. 2010 Cobalt LT Coupe Subs: 2 American bass XFL 12s Amp: Crescendo BC3500D Big 3 in 1/0awg 29hz box stinger volt meter 2nd battery Deka 9a31 pioneer DEH-9400BH Link to comment Share on other sites More sharing options...

lotus Posted March 13, 2012 Author Report Share Posted March 13, 2012 if i do the big 3 with 4awg and add a deka 9a31 would that be enough power? or do i have to use 0awg? 2010 Cobalt LT Coupe Subs: 2 American bass XFL 12s Amp: Crescendo BC3500D Big 3 in 1/0awg 29hz box stinger volt meter 2nd battery Deka 9a31 pioneer DEH-9400BH Link to comment Share on other sites More sharing options...
Kranny Posted March 13, 2012 Report Share Posted March 13, 2012 i'd do 0 gauge for your car. cause the cobalt has the stock battery in the trunk and you want as least resistance as possible. Link to comment Share on other sites More sharing options...
Omega5002 Posted March 13, 2012 Report Share Posted March 13, 2012 Well, all we are trying to say is that doing the big 3 with 0 gauge does nothing but more good for your electrical system. I know 0 gauge is more expensive than 4 gauge but its more worth it cause the current has more room to travel because bigger wires have less resistance, so it's gonna help keep voltage stable like I said before, especially since you're running stock electrical, if you use 4 gauge, the chances of voltage drops increases cause you're limiting the chance for the current to travel. If I was running 1.5k on my car, I would invest in 0 gauge to feed the amp properly, and to do the big 3 in 0 gauge also. Right now since I'm only running 600 watts rms, I'm only using 4 gauge for the amp cause it's my 1st system, and I haven't done the 3 big yet because my electrical is stable atm, and plus my stock wires are almost 4 gauge anyways.

lotus Posted March 13, 2012 Author Report Share Posted March 13, 2012 my batt to amp wire is 0awg 2010 Cobalt LT Coupe Subs: 2 American bass XFL 12s Amp: Crescendo BC3500D Big 3 in 1/0awg 29hz box stinger volt meter 2nd battery Deka 9a31 pioneer DEH-9400BH Link to comment Share on other sites More sharing options...
lotus Posted March 13, 2012 Author Report Share Posted March 13, 2012 can i use, used 0awg wire? 2010 Cobalt LT Coupe Subs: 2 American bass XFL 12s Amp: Crescendo BC3500D Big 3 in 1/0awg 29hz box stinger volt meter 2nd battery Deka 9a31 pioneer DEH-9400BH Link to comment Share on other sites More sharing options...
HunterJohnson Posted March 13, 2012 Report Share Posted March 13, 2012 what everyone said...do 1/0 4 gauge is wasting your time. I have the same rms in my car and I have 1/0 big 3 plus an extra battery in the back. I have one run of 1/0 and a run of 4 gauge to my rear battery and I still get voltage drops to 13.6 and 13.4 idle playing at full tilt.

Omega5002 Posted March 13, 2012 Report Share Posted March 13, 2012 can i use, used 0awg wire? Yes you can if it's long enough, and insulation is in good shape. 2003 Kia Sorento Team Subsonic LowsTeam Bassin' on a Budget2016 Rebuild Under Construction Best score: 150.2 at 40hz (3k, 2 Custom HDC3 15's) Usaci style(door open, in the kick) Link to comment Share on other sites More sharing options...
