Can all 4 channel amps do this?

"A common method of creating high power for a left 4ohm speaker and

right 4ohm speaker is to bridge both the front and rear channels of any Xtant 4 channel amp. The resulting 2 channels will provide double the power to each 4ohm speaker.

On X series models, the input jumper must be in the 4 channel position. Use an RCA splitter cable in front of the L/R input cable to create both a left and right high-powered channel."

My amp doesn't have an input jumper

Probably because your amp doesn't need an input jumper. But yes, you can bridge any 4-channel amp down to two channels (bridge the front 2 channels and bridge the rear 2 channels), and run the L signal to one side and the R signal to the other side

My guess (since I'm not extremely familiar with them) on that Xtant is that the jumper allows you to either use a single pair of inputs for both front and rear, or separate inputs for front and rear.

That creates a 2 ohm stereo load? Not mono?

Huh? What?

I don't know, you tell me, lol.

What load is my amp going to see if I do that?

if the speaker is 4 ohms, it will see 4 ohms. The amp will be running each single channel as it had a 2 ohm load, then when you wire those to one speaker it's a bridged channel at 4 ohms...

Butt donnn't listen of me, I am retard?

shit, I am dumb... that was pathetic on my part...//content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif

Whatever impedance the speakers are. If you have 8ohm speakers, the amp will "see" an 8ohm load. 4ohm speakers, the amp will "see" a 4ohm load.

Now that you ask that question, I think what you may have been trying to think of was that when you bridge an amp, each channel will "see" half the load. So, if you bridge a 4ohm speaker to two channels, each channel would "see" 2ohm. But, that doesn't change anything. You still have a 4ohm speaker, and the amp will output it's 4ohm bridged power rating.

No, each channel would "carry" or "see" half the load, not double the load //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

That I'll agree with

I know, I knew I said it all dumb like as soon as I hit post, but I couldn't edit it before you saw it... flame away..
