RE: WTB 94 JBL Amplifier
I cannot recall if, but somewhere in the back, cob-web filled corners of my memory I slightly recall there being a difference between 93 and 94 JBL amps. I am pretty sure that they changed amps in 95 as well, but I cannot confirm if the 93-94 were the same.
I will say though, without a doubt, that it seems that 93-94 JBL systems sound much better than 95+ systems. I dont know if that is due to amp changes, or head unit, or what. But I do know, all of the 93-94's we've had come and go, and all the 95+'s we've also had come and go, the 93-94's sounded much clearer. They were just simply "better" sounding systems.
Bill, I do not have a JBL amp for a 93-94, but I do have one for a 95....if you email me a picture of the plugs, I can check to see if they are the same.
