FIrst i love the MA Audio MA12D4 12.
Next Diamond Audio D312D2
last would be memphis audio 12. i dont have the part number but a 400 watt rms one.
It was recommend to check out the kicker comp vr. but in all honesty my friend has two and it wasnt my kind of sound.. i have never been a fan of kicker subs but definetly like there amps.. I have an alpine v power MRPM450 monoblock and a ported 12 inch enclosure.. what do you think is going to sound the loudest and clearest of all there subs. please give me some opinions.
