it will be prety much the same the 12 inch g5 will hit hard like the w7 but the w7 slighty have some better spl the sq will be the same, because u have the ho box the w7 will get louder than a regular ported but since ur talkin about the radiator will be the same as the ho so i said get the cheapest one
justin do the G5. its a very very good sq sub but its not really designed for much SPL. the ones ive heard have all been sealed so im not really sure what it can do. it has better sq than the w7 by far in the right box. i dont see why people love the W7s so much..honestly have you heard them? there not that great. sorry JL lovers.
you could do 2 12W6s and another 500/1 also. or an IDmax 12 and a nice 1000rms amp.
hold the phone.... i had a 500/1 and a 10w7 in H.O. and its was magnificent. an insulated car with perfect gains... my w7 sounded astonishing... its gone now so im looking for something new. ive never heard a G5 before and im woondering if the g5 and the radiator in a perfect (down to the .0001 cubic inch) box will disapoint me after owning a w7.
