Yeah its a heavy mutha.
RE SE's (like that one) are (arguably) one of the best all round subs on the market. They do big spl, decent sq and are ideal for a bit of streetbass action, which is what I've built my box to do. The box is tuned to 32hz and should allow the sub to be pretty musical, but also drop deep.
I'm stuck on an amp though. I was planning to use the inphase IPA 2400 one I have, but its far too big to go under the drivers seat which is where I want to put it. I need a nice small class D one I think.
The amp can take over 1000 real watts, and I don't theres many amps out there that can do that with a small footprint.
