Power Acoustik FI2X-820
200 x 2 @ 4ohms
250 x 2 @ 2ohms
500 x 1 @ 4ohms mono/bridged

Sony Xplod XS-L1235
4ohm SVC
200 RMS
800 Peak

Safest wiring configuration
Your safest way is to wire each sub to its own channel. You will receive the 200 x 2 @ 4ohms rating (each sub will receive apx 200 watts). This is actually the "ideal" match for your subs.

Try at your own risk
Your amp is only listed at 4ohms Mono stable. If you bridged both subs you would present a 2ohm mono load on the amp. Some amps can handle a 2ohm mono load (even if the specs don't state it), some can't. If you try this way, start with the Gains turned All The Way Down (counter-clockwise), and then slowly increase them. If the amp starts shutting off on its own or you get alot of distortion, then immediately revert to 1 sub per channel. You may damage the amp and/or subs in the process though, so be warned (clipping is never a good thing for an amp to do). If it works, you would get at least 500 watts total, 250 watts per sub.

LMAO!!! And don't worry, I've got 10 years on you and I'm still not too old for loud music posted_image
