ok, now I bought the woofer, I got a 10" Rockford Punch stage 2
View attachment 513765
this is the 12" version, but you get the idea. It has a 4 ohm impedence, It has 200 watts RMS and 400 watts Peak and 85.5db sensitivity. Now, since I know next to nothing about stereos, help me pick out an amp to power that exact specifiations, remember only one sub, and will not break the bank, i am a poor college kid!
