Then dont try to run them on amp as most probably they will be producing something around 20-25 watts rms and an amp might simply burn them so just get any woofer, pioneer sony, kenwood in L shaped box for heavy bass or ported box for that sound quality effect on a 2 channel amp or invest once and get a genuine 4 channel amp and run woofer on 2 channels and keep 2 channels for future if u ever want to install speakers in ur car
