I love my IDMax 12, but I need a little more.

I have a single IDmax 12 and I've had it in a few different enclosures. I thought about getting another and running IB, but I keep reading about questionable build quality since the breakup. I also had to get the coil "shimmed" so I'm not sure I want to go get another one especially if they're not both the same age.

So what can I get that wont break the bank to replace/trade for the ID to run IB? I think I have room for three 12s. I can easilly get 3 10s in there. I'm still considering trying to fit a pair of 15s in my 2012 Mustang. I've removed the rear seats so I was thinking of making a baffle where the rear seat delete is(think seat backs). The only problem is I'd have to glass from the baffle to the rectangular area that is open to the trunk(where I can easily fit 3 12s).

I listen to pretty much everything. I just want a little more volume on the really low stuff. I want the cannons in the 1812 to hit without worrying about blowing up my subs. :)

EDIT: Screw it. I've talked myself into 15s unless someone can recommend me 3 12s for $700ish that will dig like the 15s and sound nice.

Guess I'll go search for 15s to use IB. :/

I'm using this amp BTW. It's an American Bass VFL 75.1 They say 800 watts and I believe them since I can make it hit max with the amp at max no clip gain.
