I agree. 8's or 10's would work better than a 12.
1 12" rated 600w in that same enclosure won't be comparable to your 1 10" zv4. Also, I think the 12 SD-2 recommends 2.0 cuft ported.
Your best bet though would be to make a center console and put 2 12's ported running 600w each.
oh yea of course it won't compare to it. I'm just looking for a basic musical system. i don't want to spend more than $500 on everything comps, sub and amps
