Hi. I just picked up a 10w3v3 in a box for $60!!! It's a great sub and sounds really good. It's a single 2ohm voice coil. I have it hooked up to a Precision Power 4200AM. It's specs are:
4 x 50W @ 4 ohms (12V)
4 x 100W @ 2 ohms (12V)
2 x 200W @ 4 ohms bridged (12V)

I think I bridged the front channels correctly: I ran the positive from one(the left or right, I cant remember) and the negative from the other(the left or right, I don't remember) to the sub.
When the sub hits hard, the low impendence light flashes. I have nothing hooked up to the rear channels.

Am i going to harm the amp by bridging it to a SVC 2ohm subwoofer?

You're overdriving the amp. It's running at 2ohms bridged instead of the 4 ohms it's made for.

^ Word.

The lowest the amp can handle is 4 Ohms per side bridged.

Simple solutions:

1) Buy another matching sub to wire to 4 ohms

2) Buy a 2 ohm stable mono amp
