is bridging means that connecting two subs cable to the save negative and two connect to the same positive in the amp??

Technically, bridging means connecting a sub (well, anything really) to the positive terminal on one channel and the negative terminal on the other channel. This lets you get much more power (theoretically twice as much, but never that much in reality). What you are talking about is hooking the subs up in parallel and bridging them at the same time. This will work (I had the same setup in my car) provided your amplifier can handle it. By bridging and connecting the subs in parallel you're presenting the amp with a lower impedance than the standard 4 ohm. Not all amps can handle that.

I'm going to guess at what you really intended to write and hope this answers your question. I think you meant to ask:

Does bridging mean connecting two wires to the sub woofer, one to the positive terminal and one to the negative terminal of each amp (or each channel of a stereo amp)?

If I got the question right, the answer is NO. Bridging means that two amplifiers are fed the same signal out of phase. That is, one input goes positive as the other goes negative. Then, you connect the subwoofer between the positive output terminals of the two amps. Many amps have a switch that automatically configures the outputs correctly.

Remember this golden rule of technology:

When all else failse, RTFM! *

-- Your description will only work if the amplifiers have balanced, floating outputs. If the outputs are single ended, with the negative terminals being ground (common in home stereo) you will not have a bridging configuration.

Well my Amps said that it's a 200watt amp. Will it able to run parallel and bridge at the same time along with my 12" 200watt subs?

I didn't buy any of these equipment so there's no hope of getting manuals. Hehehehe. What do you expect from practically free products >:)

Gee. Ever heard of the Internet?

If there is a brand name on the amp, the manufacturer just may have a site with that info. Of course there's always a search engine, like Google ;)

Wait a sec...is this a home amp or car amp? I assumed you were talking about car amps since that's the only place I've seen the setup you describe being used.

What should I do with my amp? I'm confused.

I have 8 total slots to connect the speakers (can connect up to 4 speakers)

It have 3 RCA input:

Front input
Sum Out
Rear Input

What should i Connect what to what? My head unit only have 1 RCA output, should i put it in the rear? or front?
