geez, I didn't know which old thread to resurrect so I thought I would just start this one. Came across this interesting setup that can be had in 8 ohm. From www.turnswitch.com. Any opinions on whether these would work?

6" x 9" Stereo High Output - While similar to our standard 6 x 9" stereo speaker, this dual speaker uses drivers with a response curve more tailored to open cars providing improved clarity in windy or noisy environments. With 4 ohm voice coils is only suitable for use with our AM/FM Stereo conversion or modern radios. With 8 ohm voice coils, this speaker can be used with original factory stereo radios from the mid 60's and early 70's. This speaker is very compact and light weight - about 1 pound. Compare to others using smaller drivers at over 2 1 /2 times the weight. Shown without included fabric dust screen for clarity.

Price - $99.95 Both 4 ohm and 8 ohm available. Size: 9 1/4"W x 6 3/8"L. 2" deep. 4 5/8" x 6 5/8" mounting centers.
