I have just looked at a mates 93 LWB TT as he complained that the CD head unit was U/S no sound and was going to Halfords for a new one! Having swopped over with a known working unit there is still not a whisper. Is their another amp? If so where is it? Does it have a fuse? If so where?

 

My own 1990 NA LWB runabout has sounds but pretty crap by todays standards. Has replacement speakers of reasonable standard and Sony head unit. I assume this has another amp also. A readable/ printable wiring diagram would also usefull.

It depends.........

 

Some came with the Bose system, that has independent amps per speaker, and some came with standard head units.

The quickest way would be to look under one of the rear side pods (where the rear speakers are) and see if you spot one of these...

 

 

If you have, then you have individual amps, if not, and all you can see is a normal speaker, then you have another problem.

 

Have a check of the colour code diagram >> http://www.300zx.co.uk/forums/attachment.php?attachmentid=31731

 

Other than that, on a normal system, the speaker wires go directly to each speaker location.

 

If you do have the Bose system (individual amps) then my advice would be to junk it and buy some decent quality speakers. Adaptor plates are available, normally on Ebay US.

By the rear side pods you mean in the back passenger compartments, in the boot? Sorry to sound dumb but my other car is a SWB. The LWB has speakers bodged in original apperture door fronts and some large diameter affairs bodged in the boot side panels. The boot light left removed/ dangling.

As for my mates, his has what looks like a better red coloured oval speaker installation in the door positions, not sure about the rears. As there is no sound didn't look further and my lunchbreak ran out!

Oh bugger!!

Sounds like they have both been modded already. So, as long as the Bose amp units are removed, then there should be no problem. Follow the wiring diag (although depending on year it may not be 100% ) and trac out what you have. There should only be two wires going to each speaker (original Bose had three)

it depends if it is a uk or import

all models concerned are jap imports

as far as i know the only amps fitted to imports are the bose ones Dave has already described

(apart from the starnge setup in my 95 convertable involving a stock amp in the rear under the swb specific trim behind the passenger seat that runs the front speakers)

 

it's possible if the audio hasn't worked since you got it that the previous owner had fitted an aftermarket amp which they removed before selling

 

try:

 

looking under passenger seat or boot carpet for an amp or wires that might have gone to an amp

 

look at battey to see if extra +ve wire fitted that used to go to amp

 

open door, you'll see the rubber "hose" that contains the door wiring loom, gently prise one end out and see if there are any extra speaker wires (the stock loom should be all tidy in one bundle) or look in the footwell where the door loom comes in to the car to see if there are extra speeker wires and where they go

 

does the head unit loom have the origonal nissan connectors (one 6 pin , one 10 pin i think - not all pins present) with converter leads to iso connectors or the head units connector - if so look for a wire on the nissan loom that has no wire in the head unit side of the plug / socket. this MAY be power for an nissan amp

 

also bear in mind that the nissan wiring loom if i remember correctly has no ground wire in it, the ground needs to go from the spade terminal bolted to the chassis behind the head unit to a bolt on the head unit or the head unit ground wire

I'll have a better look tonight, as only being used as a taxi for my other halfs hen night. From memory it looked like the original nissan wiring had been converted to conform to JVC set up OK with no other external amp wiring.

I will pm previous owner also. My friend said there was initially some sound, went intermittent then silence. This is why he assumed head unit was U/S.
