Hi guys! In case you can't tell, I'm new in here ;)

Okay, what I have:

- 1 10" Alpine S-type, dual 2-ohm

- Jensen XA2125 amplifier (175W x 2 @ 2ohms, 350W bridged [I'm assuming @ 4ohms], RMS ratings)

At the moment, I have the sub in a 1-cu.ft. sealed box, wired in series for 4ohms, bridged.

would it make any difference whatsoever if I wired the coils separately to each channel, or am I better off leaving well enough alone?

Yes it would make a difference. Since your sub is a dual 2 ohm coil and your amp can put out 175 per coil at 2 ohms. Your amp will put out more power in 2 ohms than it will in 4 ohms. You subs will pound harder but wont be as clean as 4 ohm. Basically what you can do is just try both ways and see what you like more. Just make sure you dont set the gains up too high in 2 ohm or you could ruin your amp.

Ah, no, that is incorrect. There is no difference operating a stereo amp bridged into 4-ohms or in stereo at 2-ohms. This will result in exactly the same power output.
