Which setup should I go with? HELP

[jus_n]

Hi there again guys I already sold my 13w7 so I was wondering if what setup I should get I want SQL:

SETUP ONE:
2 ED A 15 Subwoofers (Slot Port 4.5ft.^3 Box 28hz)
1 Orion 1200d Amp wired at 1/2 ohm to both subs
1 Yellow Top Optima Battery
150 Amp Alternator

SETUP TWO:
2 RE XXX 12 Subwoofers (Slot Port 4.0ft.^3 Box 30hz)
2 HiFonics BX1500D Amp 1 ohm wired to each sub
1 Yellow Top Optima Battery
150 Amp Alternator

Thanks For The Help Again

Id chose XXX's over A's. But, 4 ft^3 sounds a bit big for the XXX 12, that's what RE recommends for the 15.

XXX all the way, its the best sql sub out there in my opinion
