can you wire 2 mono amps parallel or in any way to 2 SVC 4-ohm subs to get a 2 ohm load? i know you could wire 1 mono amp like this. i was wondering because i want to get the the full potential out of the sub. i have 1 Audiobahn 12" ABASS12 ported sub (400w rms)and i want to get another one. the amp is Boss 850 Riot mono (200w x 1 at 4 ohms, 425w x 1 at 2 ohms). should i just get a better amp because 200w im pushing now just isnt loud enough, the bass is clear though. or if i keep the amp when i get the 2nd sub, will 425 watts be loud enough to shake some walls? i know this setup isnt that good but im a poor college student.
