My current setup is in a 2000, mustang convertible. Very little room. I am using 2 seperate boxes at about 1 cube sealed. I have a kicker 750.1 amp, powering two 10 inch CVRs. My question is, what can I drop in that will sound better? Of course the cvrs are loud, but after I tuned them there just not where I would like. I am looking for a cheap replacement. I may be able to sell the cvrs to some friends to help with cost. I'm looking at the Sundown E-10, so Skar IVX 10 Would an upgrade be worth if it, if so, what subs should I get? In short: 750-800rms, 1 cube sealed (each), daily use. What to get?
