I think the JBL (Crown) is ideal because with 3 subs your going to have a goofy ohm load, but the JBL gives the same rated power at any load from 1 to 4 ohms. It doesnt' care.
Crown is the number one maker of concert pro audio amplifiers. They know how to make amps.
I got three JL Audio 12W3v2-2's. I want to buy an amp that is going to stand the test of time. I'm not trying to go more than $1000. I'd also like to get an amp that has good sq and power. thanx
