Fusion Audio 12's and audio question

[slayer1927]

Hey everyone I got two fusion reactor 12 inch subwoofers They are nice they are 600 watts each and hit has hard as my friends two kenwoods at 1200 watts.

I have them hooked to a 4 channel sony xplod 600 watt amp .

That means they don't hit nowhere near as hard right? They are only getting what 150 watts each .

I need some help in finding a cheap but good amp that will give them lots of power .

No more then 100 if possible maybe 140

I also have blown all my doors speakers I have two 6.5 ample and two profile 4x 6 I want to get two more 6.5 and two 6 x9 to put in my 2001 chevy silverado .

I am going to have make new mounts for the 6x9 no problem but need some good one at a good price any suggestions .

Now I have had two head units since i replaced the stock . Both only have one set of rca ports How can I make a rear and a sub so i can add more power to my door speakers or am I going to have to get another head unit . I have a y spilter on both right now so I can use the amp on both sides.

let me know of any ideas I am new to car audio and want my system to sound good .

Thank you
