I have a '96 XJ sport w/ casette option and 4 speakers (not the custom or infinity or whatever option)

Any idea if the speakers are 8 ohm or 4 ohm?

 

the 96 changed up a few things but I believe they are 4 ohm... Why though?

 

interested in poss replacing speakers and leaving head unit alone
Matching correct ohms is important so you do not over stress the amplifier

 

why wouldn't you replace the old head unit??

 

The only thing I can think of is that para32 has a bunch of old tapes he likes to play.

Anyways, I believe they are 4 ohm, but not 100% sure. If anything, you might get a bit better, albeit quieter, quality sound with a higher load (like 8).
