Help: Aletc AC7300 4x100 amp

StRaNgEdAyS · 12th August 2007, 03:36 AM

I have an Altec AC7300 4x100 amp I want to bridge to run 2 subs but I do not have the schematic that would ordinarily be on the bottom panel of the amp.
Would anyone be able to help me out here?
The amp can be bridged to run either as 2 or 3 channel.
Cheers.

To find the bridge wires on this or any multi-channel amp goes as follows. Using an Ohm meter, there will be one channel's positive wire that shows a dead short to the other channel's negative wire. These 2 wires are NOT the bridge wires.

If left + shows a dead short to right - Your bridge wires are Left - and right +.

If right + shows a dead short to left - Your bridge wires are Right - and Left +
