I have found out that wiring is very important....and the box is also important.....i dont realy know anything so imma just tell you about my system and help me out of wiring please.
I have 2 15" fostgate series 1 158 subs(old). The box is seal(have been told its too small) the speakers are inverted. I have a 4 gauge wiring kitfrom wal-mart.....i have 12 gauge coming from both speakers bridged to one channel on a two channel amp....600 watts at 2 ohms(pyle rated at like 14.5 volts).....i have the negative on negative and all that. i have a crossover(180degree punch switch).
