I want to buy two 10" DVC Rockford Fosgate P3 shallow mount subs to go in a sealed box under the seat of my 02 supercrew F-150. The box has 1.05 cubic feet of air space per subwoofer and 6.25" mounting depth. My speakers I have are alpine R series powered by hifonics 400w amp. The amp I want to buy for the subs is a hifonics 1200w Brutus class d mono block. Will this be a good setup? ANY RECOMMENDATIONS? Thanks you guys I really appreciate it.
