No sound from speakers after install...

[914zim]

Fellas:
I'll apologize up front for the long post...
OK, I'm still having problems getting a new stereo hooked up in my 914.
The good news is I was able to mount the new stereo in the glove box area like the PO had set it up (see previous thread).
So, I have the constant 12V power connected to the memory wire, the keyed power to the main power wire on the stereo and the ground wire connected to the fuse block ground. The antenna cable is plugged int the stereo also. I have only 2 speakers mounted ahead of the doors in front, even though the stereo can drive 2 front and 2 rear speakers.
When I turn the key, the unit powers on and I can program stations and it holds them after I've turned the key off. I can see the little LCD meter jump up and down, so I'm pretty sure it's getting a signal.
The problem is I get no sound at all coming from the speakers.
The PO did mount an amp in the front which is what's confusing me. The amp has a terminal block for the speakers and they are connected to the speakers (I didn't mess with this at all). There is another terminal block called "high level input (l and r)", but there is nothing connected to it (never was).
There is also 2 RCA jacks labled "line input (l and r)". These were connected to the old stereo speaker connections, but when I connect the new stereo speaker wires to them, I get nothing.
My new stereo also has 2 RCA plugs coming out of it labeld "rch RED and lch WHITE" What are these for and where do they connect? I do not have them connected right now.
I've tried every combination of connections I can think of, but I can't get any sound.
Can any of you guys give me some ideas as to what's wrong here? Any help is greatly appreciated! Sorry again for the long post.

if i understand your situtation correctly, you have two speakers in the doors, and the wires for those go to the amp you have and not to the cd player.

if you want to keep the amp:
make sure the amp has power(most likely lower guage wire running to the battery) if thats ok, you should have one set of rca's coming out of the amp to the cd player, and that rca should connect to the rca pre-out labeled "front" channel, or something similar. as long as the cd player has power and the amp does too, this should be all you need. the only thing that might hold you up is that some amp require a remote turn on wire to the cd player too, to protect the speakers from the amp.

if you dont want to keep the amp:
you'll have to run the speaker wire from the speakers to the cd player and splice them in to the speaker wires coming out of the cd player..i.e front right, front left etc.

hope this helped a little.

I think you should take the terminal block out of the wiring, and pull the speakers to see if they are properly connected. Maybe I'm gauche, I just use spade connectors crimped (and "yank" tested) as tightly as I can get em, no terminal block. Maybe a hot speaker wire becomes grounded on yours.

Go to www.crutchfield.com and poke around and you'll find instructions with diagrams on how to hook up stereo/amp/speakes all in different combinations.

i think rch and lch are right and left channels. have you checked the front to rear fader? if you only have 2 speakers connected to the stereo, lets say the front outputs, and the fader function is set fully to the rears, you won't have any sound.

You got tunes yet?

Guys:
Thanks alot for all the help.
Sorry I've been MIA on this today, but I had to do the family thing today..... I did get a good solid hour on the 914.
Anyway, the good news is I got tunes.
The bad news is I think my amp is kaput.
I removed the speaker wires from the amp and connected them directly to the stereo and viola!!
So, now I'm thinking I might just skip the amp or maybe I'll by another one (cheap) and put a new one in.
On the other hand, I'd like to be absolutely sure the amp is toast. Obviously, it didn't work for me, but before I just toss it, is there any way to be absolutely sure? Aw crap, maybe I shouldn't care, since it came with the car and it is pretty old.
Anyway, again guys, I really appreciated all the help.
I knew I could count on my 914 buddies!
Later!

Were you getting power to the amp? Usually there is a signal from the head unit that turns the amp on or off.

Thanks Dave.
I'm gonna check that tonight.
Maybe my amp isn't fried.
