Pioneer GM-7100M 800 Watt Mono Amplifier -- rated at 250w RMS x 1 @ 4ohm. Given you've wired each sub @ 2ohm, you're only getting 125w RMS to each sub.

Pioneer GM-5100T 760w 2 channel amp--> Rated at 190w RMS x 2 @ 2ohm.

Wait...if its rated 250 x 1 @ 4ohm..and he's got 2 subs wired @ 2 ohms, then he's gonna get MORE than 250 to one mono channel. The subs don't split the power, they SHARE it. if it was 125 x 2 @ 2ohm then each sub would be getting 125.

resistance is not addition. 2 4ohm speakers bridged is 2 ohms. 2 2ohm speakers bridged is 1 ohm.
