Is this possible? With just separates front speakers and coaxial rear powered by a 4 channel amp and good HU produce quality sounds? I love my cargo space and I just dont want a subwoofer occupying that space.

HU - Pioneer dvh p5650
Front - Pioneer coaxial 6.5 160w TS-G1641R (to be transffered to rear )
Rear - Stock
Amp- None yet

Im thinking of buying 6.5" RA seps Q series but i dont know what amp to buy to power the RA seps and my old Pioneer coaxial. Can anyone suggest brand and model?

Or thinking of DLS seps. And I also dont know what model to buy and amp to power the seps.Thinking of V12 amp but dont know what model to buy and is it advisable to use v12 for DLS seps.

10-12K Budget included wires and labor and deadening.

thanks
