I got 2 pioneer 12's 600watts( I think)...a kenwood deck..and my bro's borrowing me one of his amps for now...I have a 89 gmc 1500 regular cab...bottom of the line...I got 4x6's up front and they ****. I"m planning on getting some pioneer 6 inches and putting them in the back somewhere and ditching the stock 4x6's and getting better 4x6's. what kind of watts should I look to run to the 6's...or should I go bigger to get lower notes cause those stockers now just squeal? should I consider getting completley rid of the 4x6's up front depsite the pain in the but it would be to make 5's or 6's fit? keeping in mind this isn't a show truck so It doesn't have to sound top of the line but pretty decent..thanx a bunch
