no optima, overpriced for the performance it gives, Xs power, kinetik and odyssey batteries is where its at. 130 amps is good enough, just upgrade the battery and monitor voltages.
Thats a lot of room so i'm assuming you are not using your 3rd row seats? that makes things a lot easier(i was assuming you'd want the 3rd row seats), you can even fit a pair of 18s if you want. If you are a crazy basshead, you can plan ahead for the future and build a seperate chamber dual 18" enclosure, run only 1 now and in the future you can add another.
