2 L7 15 in 4 net cubes each tuned to 38 hz in an ext cab tacoma. 1800 watts a piece. Hairtricks all day. You have a suv. You could put put a straight 1200 watts on 1 L7 15 in 6 cubes tuned to 32hz and blow those cvr's away.
Get another 1200.1. Maybe swap up to a 2500.1 if you have the right voice coils. Probably gonna need another batt too.
