when i bridge my 2 channel does it basicly becoem a mono amp or what

no it doesn't become a mono, well I guess it does sort of. But it can't handle the same ohm load that a Class D mono amp can. Most, if not all, 2 channel amps when bridged can only handle 4 ohms.

what amp do you have? The amp itself does not become 2 ohms. The ohm load is dependent on how you wire your speakers.
I'm 99.9% positive that there is not a 2 channel amp out there that when it's bridged can handle a 2 ohm load. Have fun clipping your subs and blowing them.

Bridging a two-channel amp can be a decent way to run a sub, depending on the amp and the configuration. If you run a bridged 2-ch amp with a single sub (Assuming 4-ohm load) you are esentially presenting a 2-ohm load to each side of the amp. If the amp is rated to be bridged, it will have a non-bridged, and a bridged minimum resistance rating. Going below that rating is almost a guarantee that you are going to damage the amp, the subs, or both.
For example, if you have a two-channel amp that is rated to be bridged to 2-ohms, you can bridge it, and then run 2 4-ohm subs in parallell to present a 2-ohm load to the amp. This means that each side of the amp is now handling a 1-ohm load. This example (http://www.crutchfield.com/S-lP6fGzPD03B/cgi-bin/ProdView.asp?g=110&I=575T8002) (crutchfield.com) will handle such a set up.
You will not find many amplifiers available that can handle a 1-ohm load per channel, so the above example does not apply to most situations.
Most two-channel amps that can be bridged are rated for a 4-ohm load when bridged, meaning that each side is being presented with a 2-ohm impedance; most bridgeable two-channel amps are like this. example (http://www.crutchfield.com/S-lP6fGzPD03B/cgi-bin/ProdView.asp?g=110&I=575P8002) (crutchfield.com)
In the more common case, the easiest solution is to wire one sub directly to the amp, for a 4-ohm load. Two subs may be wired in series, presenting an 8-ohm load to the amp (more stable for the amp, better SQ but less power). For a multi-sub setup, two sets of two subs wired in parallel may be wired in series (4/4=2, 2+2=4 ohms) to present the amp with a 4-ohm load.
Personally, I prefer to wire a two channel amp as two channels, and run 2 smaller subs, one off of each channel.

Most 2 channel amps can handle 2 ohms in stereo though. Just run 2 4ohm DVC subs, wire the VCs in parallel and wire the subs to each channel.
This guy thinks his amp is stable at 2ohms mono though.

you could do that... i'm using equipment I already have, so the setup I prefer is the one I have ;) besides, as long as you match your amp to your subs correctly, there is no reason to run them at anything but the regular-old 4-ohm loading- it's where they were designed to run, and is the most stable load for the amp (unless wiring in series).
