You'll DEFINITELY want to have things dialed in for your new found "thump" - if you get someone that knows what they're doing to handle it, the system could sound REALLY good.

It shouldn't be TOO insane since they're being run with a single 1000/1. Don't get me wrong, it'll still pound, but those subs can realistically handle a 1000/1 EACH.

I have a single 10W7 being pushed by a 500/1 in my 135i and the sucker POUNDS when it's cranked, but is probably one of the nicest sounding "stock-ish" systems I've heard when played at reasonable levels.

You cannot have two12w7's and keep the same highs that come with the car. The bass will drown out the high's. I have 1 jl 13w6v2 with a jl 500/1 and it is very loud and the bass has to be turned down low so it doesn't drown out the highs. Also a 12w7 needs it's own 1000/1 to be driven properly. 500 watts going to that woofer will not get the full potential out of it. Go with 2 12w6's instead and the 1000/1 driving them. Your box will be smaller as well. just my 2 cents

Damn, thats a lot, what about weight, I have 2 fosgate T1 subs and each has a weight of 30lbs. But those subs would be underpowered as they can take at least twice as much power.
