how to bridge an amp properly

i have a 2 ch 1200 watt sony xplod amp, i was wondering how to bridge it, some people have both positive terminals hooked up, and others have a negative and positive hooked up, and others have the pos and neg hooked up and a wire connecting the other ops and neg terminals.
thanks

most amps have it printed on the heatsink which terminals to use. but, its usually the negative from the right channel and the positive from the left channel. no other connections are needed.

Usually left positive and right negative

As said, it will say right on the amp. Usually lines drawn on the amp connecting the two terminals you need to use. Usually says "BRIDGE" on it

No idea what the BTL stands for.

Try throwing in a differnent pair of RCAs and see what it does...

You said 'subs' right?

Perhaps they are out of phase; pulling one i/p cable let's one run unmolested by the output of the other.

if your subs ar getting louder when you unplug the red rca cable because your subs are wired out of phase..... before you try bridging the amp try reversing the wires on one of the channels... alot of beople think bridging is end all be all of their problems... its really not tho

This is how you bridge a sony xplod amp, and a sony xplod amp only. Find the tallest bridge you know of... And throw it off the side.

BLT = Balanced Line Transmitter. Obviously NOT the case when we're talking Sony though.

To the OP .. 99% chance your subs are out of phase, follow instructions above.
