Thanks Frank,
Maybe he will chime in here on this one.. But I believe I have asked him already about premium sounds and if I recall correct. He stated to me that he does not mess with the premium.. Only the JBL..
Hello again Karl,
I'm chiming in......hopefully to clarify things a little.
I do take care of the "Premium Sound"
AND "JBL" radios from
'88 to '93 Ford Vehicles. Specifically the ones with the "Paddle" style volume control in the upper left hand corner of the face plate.
Actually, there is absolutely
NO difference between what is called Premium Sound and what is called JBL
as far as the radio is concerned.
The difference between the two audio options lies strictly with the amplifiers, speakers, and the addition of a sub-woofer with the JBL option. Both options use the same radio.
The only difference in the radios is whether they have the internal circuitry to work with a factory CD Player or not and whether they have a built in clock or not. Radios built for Thunderbirds & Cougars from '89-'93 have a built-in clock. Radios made for others such as Taurus, Lincolns, and others don't have the built-in clock circuit because some of those cars have a separate clock elsewhere in the dash.
I scanned back through my old emails and found our correspondences and found that the radio you purchased off of eBay was a later model of a different type. That particular model uses a lower voltage "amp turn-on" signal than what your current Premium Sound amp needs, so, it will not turn on your factory amp when you turn the radio on. It can be made to work by switching a couple of wires in the main power connector that feeds the back of the radio. This appears to be what I told you a while back.
I'm not sure what radio(s) you have now but I am always willing to help others out. If you can tell me the Ford Part Numbers of the radios you have now, or, post some pictures of them, that would be a good start. Also, please verify that all of the factory amps, plugs, and wiring are intact and connected properly in the trunk. Lastly, if you DO NOT have the factory CD Player installed, check to see if there is a what looks like a dummy plug plugged into the upper right hand connector socket looking at the back of each radio. This dummy plug actually bypasses the need to have a CD Player connected in the later style radios.
I'm sure you'll get the issue solved.
Regards, Paul
