PREMIUM SOUND PROBLEMs

OK, i bought a new CD player for my '86 Merc. The previous sound system was stock. It has premium sound. Now, when we wired the cd player to the original harness, we only got sound out of the back speakers. They would cut off when i got the volume too high. So we treid wiring the front speakers directly to the CD player, now i get sound out of all the speakers. BUT, the sound will often fade away or cut off for no apparent reason. Do u have suggestions? or should i just driectly wire the backs to the CD player also. THX

In your current configuration, the output of the new CD player is feeding the input stage of premium sound system booster amp (in trunk). Total audio output power is limited by the output capacity of the premium sound system booster amplifier.

You will never be able to play system louder, while going through booster amp, than what booster amp was designed to produce for output level (output power of devices is not additive).

If the output level of new CD player is significantly higher than the OEM radio was, then you will be overloading input stage of premium sound system booster amplifier.

I don't have schemtic of the booster amp, but my guess is that it has thermal switches in its design and is shutting down on you when volume is high and there is excessive thermal dissapation on heat sinks. This will cause your fading out issue. If sound becomes distorted when it "fades out", then it is going into shutdown. Or, the design may be using variable negative feedback to limit destruction from input overload.

Best option, if your new CD player has higher output power (watts RMS) than premium sound amp, then wire new CD player/amp direct to speakers.

they also make special harnesses that by pass the amp so u dont need to mess with wires its just plug & play

Thats gonna solve my problem, thx but where do u suggest i find one of these harnesses?

i got mine from http://www.crutchfield.com there awsome with audio components and are really cheap in prices
