You need to match your amps ohm rating to your subs ohm rating... Depending on how many subs, and what configuration they come in, this will determine which ohm you will wire them to your amp.

and also.... just cause ther DVC dosent mean there more powerfull!

whatever you're ohm load you're amp put's out the most power at... wire you're sub's accordingly..

normally just run it @ the lowest impedance the amp can stably handle

most of the time

2 channel bridged = 4 ohm stable

mono amp = 1 ohm stable

2 channel bridged = 2 ohm stable
mono amp = 1 ohm stable

Not true in either case. For a 2 channel amp that you will be bridging, assume that you will only be able to wire it to a 4 ohm load. I would say that less than half of all mono amps are 1 ohm stable as well. Most are only rated for 2 ohms.

you will need to match it up with amp specs, get back to us on an amp you would like or some your looking at and we can give you opinions.

vague... If your setting up your mids and highs go for a 4 ohm load, better sound quality. If your setting up your subs go for a 2 ohm load, the lower the load the more power you pull from your amp.

That is entirely dependent on the amp in question...

Examples that make a lie of that statement ~

JL Slash-series amps - same wattage output on any load from 1.5 Ohms to 4 Ohms

PG Xenon-series amps - same wattage output from 1 to 4 Ohms

Certain JBL amps that increase power output from a 4 Ohm load to a 2 Ohm load but offer no more power when shown a 1 Ohm load though the amps are 1 Ohm stable.

I'm sure there are more examples that escape me at the moment...

the amps in question are

http://www.millionbuy.com/kolqx4960.html Bridged = 2 channels instead of 4

http://www.discountcarstereo.com/detail.aspx?ID=552

2 subs on the kole amp bridged. and 2 on the profile on each channel.

the subs im using are 4 http://www.pioneer.eu/eur/products/25/130/201/TS-W256DVC/index.html

all i gotta do is wire the subs to 4 ohms right? what do i have to do to make this setup possible? thanks for any advice

As I said in the PM you can't do what you want to do.
