bro, maybe your expecting too much from your budget setup, don't overdrive your amps baka masira lang. Your amp, the V12 705, isn't a power amplifier (trust me here). If your really serious about SPL consider getting Class D amps (mono amps designed to power subs), these babies deliver serious power (depending on the model) and is more efficient. Ofcourse with more power, you will stressing your charging system more so its a balancing act.
