IF you have one sub you can not wire a 4 ohm load if the sub is DVC. I mean in theory you could run one coil but DO not do this. you need a second sub or different ohm load of subs. if you have any questions. audiobahn has a wonderful wiring diagram

What are the power ratings for each? (sub and amp)

Amp:

SONY XM-752X amp, crossover, bass boost,

2ohm stereo stable, 4ohm bridged, 75x2w or 200x1w,

45hz bass boost, 400w max

Sub:

Insignia 12" 4-ohm dual voice coil 1800 max 600 rms

200rms bridged? If you run it at 8 ohms then your sub will be severely underpowered.

Model #'s would help also

so should i wire my sub at 2ohms and wire it to 1 channel on the amp or can i still bridge it at the amp?

you need a different amp, i know you dont have the money but your not going to be able to power this sub efficiently. wait till you get a new amp it will be worth it. you cant run your amp bridged with this sub because it is a D4, if it was a D2 then you could run it bridged with a final load of 4 ohms. your amp is not stable under 4 ohms while bridged.
