Ok, im looking for a new sub to buy in the next couple months for my new honda civic that im getting soon. I was thinking about just getting one sub since 2 subs take too much room. Right now i have 2 rockford fosgate xlcs, aren't bad, but id like more spl and better sq. From what i hear, the idmax is supposed to be the baddest sub on the market for both spl and sq. Now at $449, is it worth it for this one sub, or is their other subs that i should consider? And another question is, what amp should i get that doesn't drain my electrical system?
