mish...thanx sooo much for being so thorough. however, this doesn't change too much of what u said but i am running ONE sub to the bridged ch 3/4 of my amp. in other words, it's a SINGLE 2 ohm rated dvc sub wired in a series to those 2 channels making 4 omhs at 150w. haha i accidentily plurified my wording in my original post, kinda like how ppl say "headerS" instead of header for our 4 bangers. haha.

i'll check for leaks right away, in fact, come to think of it, my IDQ came with 4 qtr pieces of foamy gasket? stuff...it's still in the box!!! should i goto my installer and tell him to stick thoses pieces on? how crucial is that gasket?

** oh i almost forgot, i have a 4ch amp so i have 2 separate gain pots for each pair of channels. when setting my gain, they both need to be the same? er? my deck 4v preouts...approx where should my gain be set at? or does it all depend?
