Old SDA SRS...can you change crossover to 1.2?

autoconsortium

If my original SDA SRS speakers cannot handle monoblock amps, can I upgrade them to the newer system the 1.2 has? I need to modify the crossover as well? This is a different interconnect not compatible in any way with the original SRS speakers???? I am good with a soldering iron and making wiring, should the need arise. I just need these old SRS's to be able to run on monoblock non-common ground speakers. I'm not selling these monoblocks, as I prefer the power handling and sound quality of monoblock designs.

Check out this thread by DarqueKnight. It will answer your question.

What you can do is make a non common ground interface for them. Go to this site Click on Publications and click on A1 interconnect instructions. It is just an isolation transformer to prevent a direct connection between the speakers.

What serial number range are your speakers? That will determine what you need to do. Many of us here have run amps in bridged mono. I was lucky enough to get an original Polk non common ground interface with my SDA's.

A little review here. In this thread, post # 6, BobMcG had said "All SDA-SRS channels have to have a serial number of 5001 or greater in order to qualifiy for AI-1 use." There is a chart posted in many of the AI-1 interconnect threads showing the serial number range for SDA speakers that cable is compatible with.

OK, I found the chart. Add a pic of an exposed isolation transformer.
