honestly if u look at it u didnt spend that much money u would feel twice as worse if u paid retail for that sae amp. try buying subs and amps etc etc etc. yes its an expensive hobbie but its addicting...
anyway were all always here to help you out to stop blowing fuses amps subs hah :
edit: that sounded weird i mean try buying multiple 18's and amps wire where 2 subs are a little over 800 and amp alone 600 wire 50 it does add up
