That sounds like a nice logical way to wire these up. AS for the amp, I work at Best Buy so I get a good deal on the stuff they sell. Mostly it is just a couple of Rockfords, Sony's, Jensen's (On a clearance now, new models coming out.) Then some lightning's too.
I was thinking about $150-200 for a price range. (so money goes a little farther through work.)
What kind of power range would be good for these 2 subs?
