CURRENTLY this is what I have:
2006 Cobalt SS Sedan
BRZ-1700.1D Amplifier (ran at 2ohms - "1200w" RMS)
4 awg Rockford wiring for Amplifier power/ground
16 awg Rockford wiring from Amp-Sub
1 SA-12 D4
2cuft custom ported box tuned to 34hz (built myself)
1 Rockford farad capacitor (yeah don't judge, put it in years ago on my old Infinity Kappa system, have noticed decreased headlight dimming and seemingly more dbs when I installed a while back but the dbs could just be me haha)
600CCA 330 Load test Amps ACDelco battery
130amp Stock Alternator (90% sure, have to double check)
Adding another SA-12D4 and running the amp at 1ohm ("1700w" rms split between the two before box rise and such)
Building a ~4cuft with probably the same tuning (Probably slot ported again)
Most likely sealing off the trunk if I can figure out how to do it without ruining my trunk
Now, my question is do I need to do the Big 3 on my vehicle and/or add/replace the battery before adding another subwoofer? In this vehicle the battery is in the rear so running wiring requires me to tear apart my car which I'm not too fond of doing. Replacing the Alternator is well out of my budget as well. I'd rather just pick up a 2nd SA-12 so each sub is getting a -maximum- of 850w RMS instead of the max 1200 RMS the single sub is recieving now (so I don't overpower it so much). I know I SHOULD upgrade the electrical to get the most out of the subs, but do I NEED to with what I am running now? Will it harm anything?
- I cannot get a second subwoofer AND upgrade the battery/add a second.
- I also cannot afford a new alternator
- The Big 3 really pushes my budget considering supplies for it alone are $100 for the 0 AWG + terminals(ring and batt), including the parts to crimp and solder I don't own and the knowledge to correctly tear apart my car... don't wanna pay BestBuy $80 to do it either.
On one last note, should I replace the power/ground for my amp with 0 gauge wiring and the speaker wire to 12 AWG from the 4/16 that are in it now? Will it make a large difference, and if so what fuse size should I use?
I know this is alot of information, but I would rather be thorough in my initial post than you having to read me respond to 400 questions. This should keep it to under 399 questions .
Thanks in advance for the input!
