depends on the subs post the specs for the subs and amp, are the subs single or dual voice coil what ohms, what models, chances are your amp is only bridgeable to 4 ohms but if you post specs we can tell you more
the amp is a 2 channel 100 watt rms into 4 Ohms. i have 3 10" subs 2 of them are 150 watts rms 4 Ohm's each single voice coil the last subwoofer is 75 watt rms and i'm pretty sure it's a single voice coil as well
no. you don't want to bridge a class AB amp and run 3 different subs on it. you're better off putting the two matched subs on that amp and getting a separate amp for the third sub.
aright i just have my 2 subs wired can bridging them make the sound better i know how to bridge them them but it just sounds almost the same i thought it was suppose to put out a little more power
