I gotta 06 silverado crew Canadian version and I have a 13tw5 and I'm not real excited about how it's working. The bass feels shallow which is expected from a shallow mount. Anyway I'm gonna sell and I'm looking at 2 options:
Amp I'm running is a Rockford 500 watt at 2 ohm

Probox 04CCC110L-750
Or sub thump dual 10 underseat.

The probox comes with a 750 rms sub and a vented box with pretty good air space for my truck but I'm wondering if that 1 10 with a vented box would hit harder than two 10s non vented. If I go with the dual 10s what brand/sub would hit the hardest again I only have 500 watts

Any thanks is appreciated
