OK,I have 2 10" Infinity 1042's.I have a pair of Infinity 6.5",a alpine deck,and a old model 3553 4x75 Alpine ampI was told I should use this just for the 6.5's,and buy a 2 channel amp.I didn't buy an amp yet,and I thought I'd get some advice from you guys.Oh,I am getting the amp installed,I am not doin it myself. Thanks
