I have two Visonic 12 inch subs in a bandpass box with a Lanzar Vibe256 1600W amp. Is it possible to bridge the subs to the amplifier? The subs are 4 Ohm and the amplifier is 2 Ohm stable(I looked the amp up on Online; also purchased the amp there)

The only way you can safely bridge those woofers on that amp is to wire the woofers in series for an 8ohm mono load.  The amp will produce the same exact amount of power in that load as it does into a 4 ohm stereo load.  You will gain absolutely nothing by bridging it.  If you had 2 8 ohm drivers, then yes bridging them on the amp would be beneficial to you.

Thank you for your input...what is really weird is I only had one side hooked up and both woofers were moving. So if I hook up both sides will I gain or lose power?

They were both moving because they share an air mass between them...

You'll probably lose power, but gain output, because the drivers will both be working against this same air mass. You're lucky you didn't break the woofer's suspensions... That is an EXTREME mis-tune, and is very hard on hardware. Not that they are even good woofers to begin with, but fix it, before you break something if you haven't already!!

Haha no I didn't break anything. I plan on upgrading my subs over summer..just needed to hold me over for a bit...only thing is I have a extended cab Dodge Dakota truck so they sit in the back seat...they do produce good sound but I think if they were in an enclosed space like a trunk, they do even better. So what's better with losing power but gaining output?

I just want them to sound like they did last summer which was awesome! A lot of people could hear me and the right type of song had those really making some noise

<sarcasm> Seriously? How long have you been INTO audio, anyway? </sarcasm>

Output is how loud it is. Louder than your current situation, with less power on tap. Huh... I wonder which is better. Not to mention the fact that your woofers are actually going to survive to get replaced.

LOL I have had these subs for 2 years and really haven't had a major problem with them...couple years into audio...I was way back when I had my first system in college but it was small..and they were in my Oldsmobile Cutlass. That was over 10 years ago..lol! With more space sitting in the ext cab of my truck I feel they can't do what they should...IDK..lol!

One Postive, One Negative on each sub side by side...the little square metal ones
