positive to positive,negative 2 negitive,it will bring the 8 ohm and 8 ohm 2 a final load of 4 ohms

It's a 4 channel amp right, in bridged mode you get two 4 ohm channels.Channel 1 & 2 bridged form the first channel. Channel 3 & 4 bridged form the second channel. Your choice is to use one bridged 4 ohm channel to power your pair of subs, the subs are paralleled to form one 4 ohm load. The other bridged channel can be used to power something else utilizing that amount of power at a 4 ohm load or you may choose to un-bridge that one channel and power some separates, coaxials whatever, at a lower power demand in 4 ohm or 2ohm.

OR you can run each sub on a pair of bridged channels. (Ch1+2 TO ONE SUB, 3+4 TO THE OTHER)
The power can be estimated by summing the 4-ohm power output for a pair of channels for an 8-ohm load in bridged mode.

bridge dem,u will get mopre out put,eack speaker is 8 ohms,so wen u bridge yur amp,power will split half and half on yur 2 speakers,so running the 8s on d pair of pair of bridged channels will jus be wasting 2 channels,so 1 bridged channel will do d wok!
