hey what do u guys think of thiis amp powering two alpine type r subs its a kicker sx 900.4 would this be a good selection or should i get the sx 700.4 the rms on the subs is 500 and the 900.4 has an rms of 450 @ 4 ohms by 2 and my subs are 4 ohms aswell the 700.4 has an rams of 350 by 2 @ 4 ohms

I would go with the 900.4 cause it has about the right power for the subs.

holy crap $700 for the 900.4 amp anyone else know where i can get it cheaper

anyone have a better idea i need somthin with like a 350-500 by2 rms for my subs @4 ohms
