Kicker amps are solid and I have personal experience with them. I know RF are really good too. Get dual 1ohm FI Q and wire it to 2ohms. Go with the kicker, it's more powerful. Build quality here won't be an issue if you went with either though.
i have a q and u would get d2 to wire it at 1 ohm. both amps are 1 ohm stable. but i was just makin sure about the quality of the amps. out of the two which has the most power
Some say RF is better build quality, then again there aren't exactly masses of people complaining about kicker's build quality. Kicker is solid, if you get it you won't be wrong. kx1200.1 is more powerful than t1000bd. I was thinking you can get kicker zx1200.1 and run that at 2ohms. It's usually better to run stuff at a higher impedance.
Now I'm making up amps lol I meant zx1000.1! It can put out more than 1000W at 2ohms and the Q should be able to take it. But I see the kx1200.1 is pretty cheap! Even if RF is better built, you won't be sacrificing a lot of it for $100 less.
