Can I combine two channels on a 2 channel amplifier to double the power output?

Question

I have an old Crate PA-600 powered mixing board with two speaker outputs (Im assuming one is left and one is right, however they are only marked as "speaker jacks"). It says that it outputs 190 watts at 2 ohms, and 125 watts at 4 ohms. I want to take advantage of 190 watts at two ohms, however I have two 4 ohm single voice coil speakers that I will be hooking up to this unit.

What I'm asking is if the following scenario is possible. I want to combine both channels into one channel, then wire my two speakers in parallel to this bridged channel. This in theory would give me 190 watts of power over two speakers with a 2 ohm total load.

I currently have it setup so there is one speaker per channel, 4 ohm per channel, but only 65 watts per channel. I want more power because the unit starts to clip when I turn it up to the volume level I want it at.

This unit is very old and did not come with any manual. Here is a picture:

Here is a picture of the back of the unit.

The unit can definately handle a 2 ohm load, it even specifies it on the back of the unit if you take a look at the picture I provided.

Answer 1

If it is not marked for bridging you cannot connect it.

Answer 2

nope, don't even try it. put a 2 ohm load on this baby and you'll for sure fry it. it's old and not meant to handle it, i'm surprised it can handle 4 ohms to be honest. an amp needs 1)to be stated specifically that it is 2 ohm stable and 2) be capable of bridging, both of which I can't see this amp being.

If you want some real power, get some new speakers, spend a couple hundred bucks on a new unit.

Answer 3

2 channel means there are two seperate channels to connect ur speakers. (Left Sub) -/+ (Right Sub) -/+ MONO is only one channel -/+ Mono amps produce more power....U can see that u can hook up the subs normal to a 2 channel amp because each sub has a neg and pos wire and u run each sub to each channel on the 2 channel....On a Mono amp u would have to run the two subs in parallel (one into the other) and from the last sub into the 1 ch of the amp.....U can however bridge a 2 channel amp,but again ur better off getting a MONO BLOCK amp because it actually gets about 80-85% of the rated power as compared to only 60% of a 2 channel.....THATS THE REAL DIFFERENCE
