I just bought (2) AUDIOBAHN AW1251Q AW1251T subwoofers:

Power Handling: 400 watts R.M.S. Frequency
2" 4-Layer ASV Voice Coil
Dual 4 Ohm 2 Ohm or 8 Ohm Operation

Also a BOSS R850 850 Watt MOSFET Power Car Amp:

Max power @ 2 Ohms - 850 Watts x 1
RMS Power @ 4 Ohms - 200 Watts x 1
RMS Power @ 2 Ohms - 400 Watts x 1
Remote Subwoofer Level Control
Line out for multiple amp hook ups
Variable low pass crossover: 50Hz-250Hz @224db/octave
Variable subsonic filter: 10Hz-40Hz @24dB/Octave
Phase Switch
Mosfet Amp
Class A/B

Q: Did I make a major mistake, or can I drive these 2 speaqkers with a one channel amp. If so, how do I wire the one channel to the speakers so I that I don't blow anything up?

Any help would be appreciated.

your amp doesn't really match your subs perfectly. the only way i can see you hooking this up, is wire the DVC subs each in SERIES, and then wire them to the amp in PARALLEL, so that you have two subs wired to a SINGLE 4 ohm channel, getting 200 watts RMS. if you had gotten the 2ohm voice coil subs, if there were any offered, you could have had the two subs at a single 2 ohm load to the amp.

you should have bought two single coil 4 Ohm subs for a mono 2 Ohm stable amplifier.

I take it you're not asking for commentary on your choice in equipment brands though.

actually, as a more complicated option, you can wire ONE sub in parallel to 2 ohm and the OTHER sub in series to 8 ohm, then wire them to your amp and that would be a 1.6 ohm load. that's CLOSE to 2 ohm. and you'd get 400 watts rms+, the only thing is, you then wouldn't want to turn up your volume all the way because in the upper ranges of power your amp would DISTORT and could ruin your subs' voice coils.

but with what you've got, the 4 ohm load setup is the SAFER one where you're not in danger or blowing anything up. in the second setup, the extra 200 watts RMS would only be a difference of 3 DBs louder.

It's a Boss amplifier.
I'd be surprised if it handled a 2 Ohm load well.
a 1.6 Ohm load would send that amplifier into protection mode, if he's lucky.
The amp would set fire to teh trunk of his car if he's more on par with the average Boss product.
