Non Truck Stereo Speaker ?'s

[SCOTI]

In our 02 TransAm, the rear sail panel speakers don't seem to like Pantera or FFDP....

The originals lasted several years & then puked. The 1st replacement GM speaker set lasted a couple of years. The 2nd set is now crapped out & these are getting difficult to source.

This is just the complete factory system (monsoon) consisting of the OE head unit, 2 door speakers (separates), the 6x9 sized mid-range sail panel speakers (they're actually a little smaller than 6x9's), & a small sub in the rear hatch area.

But, they tell me I can't just pop in any old 4ohm speaker as these are apparently 2ohm. Readily available stuff isn't easily swapped & I have zero interest of ripping it all out for a new system.

Any suggestions for a quick & painless (labor & cost effective) swap for the sail panel speakers that won't require swapping any of the other equipment?
