First post here, so bear with me.
I am looking for a way to bridge two identical (car)audio mono aplifiers 1 ohm stable.
Is it possible to use such a product?

I understood that there might be a problem to power the above article, but can't this be done with the dc/dc convert inside of the amp?
Also regarding the common ground for the bridging (if possible?) Can't this just be connected together from each amplifer?
Would be nice if anyone could answer, as ordinary car audio people don't seem to have that much knowledge about it.
If charts over the aplifiers pcb's is needed to answer, I'd be glad to provide them.

If I had to place a bet - I would say that the outputs of your amps. are already bridged - which means you cannot use 2 amps to increase power - unless you have a dual voice coil speaker - one amp per coil.

If your amps outputs are completely floating with respect the ground and positive then it might be possible to run them in series on the outputs to obtain twice the output voltage. Check the manual.
It doesn't state anything in the manual. But I'd be happy to post the chart over the PCB. I am not really that good at reading it myself.

Hi john,
You are right about this amp, but there exist a way by which you can bridge an already bridged amp. but it requires seperate power supplies for the proper operation. Crown and Qsc [pl9.0] uses grounded bridge topology for this type of implementation.

Well, delighted to hear that it's possible with other products.
About the seperate power supply, what needs to be done? Can I use the above mentioned product, or are there any other ways to bridge an already bridged amplifier?
If anyone knows how to compress a pdf into a size that this forum allows, I'd be able to post the pcb chart. Unfortunately its 1,1 mb zipped.
