seems a bit of a botched package that. A 1 channel amp that needs to be connected to 4 voice coils!!!
Not sure what would produce the best power getting 4 (2 if u look at it a different way) to run properly.U'd need 8 thick ass phono cables attatched to the amp out, (4+,4-)to go onto the 8 terminals on the 2 subs.Prob best to wire em all in parralel (2ohm) but then im thinking about amp damage.Can sanchez help??? and maybe enquire thru that website as theyre the specialists
