Looking great so far - - - keep it upand hurry up!!
To the jackass about Crunch vs JL - - - JL is not "better" than Crunch, it depends on what you need the most - the power or the "cleanliness" I reckon you could say of the JL. You wont notice a difference in sound, that's fairly clear to say. The Crunch's are 1/2 the price of a 1000/1 and put out roughly 3x the power...hrmmmmmmmmmm...your statement bewilders me
However, the JL 1000/1's are still great amplifiers, just overpriced and a bit inefficient. If you already have four of the 1000/1's laying around...use them - why mess with changing it all? Those DP21's will love 2k rms each
