Now i know I need an amp and i have one that came with the car it is a Rockford Fosgate Punch 601S and the details on that are
* 150 watts RMS x 2 at 4 ohms
* 300 watts RMS x 2 at 2 ohms
* 600 watts RMS x 1 bridged output at 4 ohms
* stereo or bridged mono output
* 4-ohm stable in bridged mode
Now what else will i need? Im gonna build a box for the subs but anything else i need? So far my total is 630 now if there are any better products for cheaper let me know.
