DC sounds great and they boom well........Diablo has hellla power and sound RELLY good as well.....you will not go wrong with those. THe customer service with both is off the wall....Phone, email, forums, messengers, they are there
the lvl 4 are awesome...my buddy has 2 10's and they hit NICE......be he is also going to upgrade in a few months..
you got 2 SD 1200...go with the XL's
true,,thats right that was all I had when I did mine....I should get around to buying some new fuses sometime.....
and true I forgot about that....sorry I believe mine is hooked up that way, but runs to jl clean sweep with a signal sense turned on.
we will just assume a 2000 rms( might be a bit much)
2000 watts 80% efficency := 2000/.8 = 2500 watts
using the crest factor (of pick noise for avg) := 2500/4= 625
divide that by a minumum voltage of 12 := 625/12 = 52.083 amps
so the 90 you have should be good....there may be something else wrong I dunno where to begin to tell you to look besides checking to see if there is a stray wire from the speaker connections
..true..but if the voltage stops you reached the limit of the amp..and clipping is pretty much a sure thing then..dunno how often that would happen though I think i was just throwing that in there
