Subject: RE:C4 Audio Installation Tips and Techniques - 1984-1989 by NC Kid on 2007/12/8 17:13:07 Gee, I appreciate the kind words on the system. I got it fixed though. Had the system installed back in March of this year. It consisted of two 6 1/2 inch speakers in the doors, 2 speakers in the wheel wells( 4x9s I believe) and then a box with two twelves with the amp attached. Wiring is poking thru the carpet. They told me that the 6 1/2s would not fit so they "returned them" and put in 4 inches. The bill said 6 1/2s though so yea.....Worked for a few days and would start acting up. At first, it seemed it would have been the alternator because it generates the juice and if it was going bad, then that could make the radio skip/cut out, similar to a scratched up CD. Wasn't it because we put in a new ACDELCO one in and still had the problem. Took it back to them and they said it was my Digidash causing the problems....True the digitaldash was messing up but that I don't think it would interfere with the radio frequencies. We took it to a electrical shop independantly owned. Basically it was a shack behind some guys house who did this on the side as a hobby. He had it for about two weeks and said he switched out alternators and it was still the same issue. Interesting enough, he put tinfoil around the distributor and stuffed it inside the cockpit area behind the CD player and it worked fine for awhile. Why, I have no idea but he said they should have come with a shield and the shop removed it for some reason. Don't know the details on that but it was fixed temporairly. He did note that a permanent shield should be made. My dad took some sheets of tin and fixed it around the CD player. Again, fixed it temporairly but the skipping came back. We kept playing with the tin foil and it worked until I hit a bump and it would bounce again. The wires I had on them at the time were ACdelco's as well so I would not have thought against them. We did replace the distributor, dist. cap, rotor button, plugs as well. Fast forward this to recently, still battling it, and me getting pissed and searching the internet and tinkering with it, still no success. I took it back to them and they said it was the ignition causing it. They claimed that the motor was "large" and gave off "interference". Don't the C2s or C3s have 427 big blocks? Mines a 350. Not big at all. We called our mechanic and he said to have them install a filter on it and change out the plug wires to some from NAPA. Ok. As of now, the radio is working. The filter was around 50 dollars plus a few more dollars for "miscellaneous". Im going to add that there are no speaker covers and they want 200 dollars to fabricate some up. The originals were damaged so I did not keep them but I was stupid not doing that. The the filter was just put in and I have not been able to drive it for more than 30 minutes because it is going to a GOOD mechanic to get looked over. If the problem persist, I will post back. The wiring is hard to describe but I am going to try to describe it. Where the rear shade, the carpet directly below it does not fit flush and flat like it did before and you can see the wires go down to it but they are hanging in the air to the amp because the amp is on top of the box. Wires are spliced on teh ends and then screws are holding them onto the amp. They then go down behind the carpet. They did NOT bolt down the box so I did that myself with some shoulders for shelves. The rest of the carpet is undisturbed and I doubt the seat has been removed because I would feel the wires underneath or notice it has been moved. The rear compartment has no wires in it either. Now wherever the wires are going, I can't find. They then pop out of the firewall right behind the battery and are wired down there. There is a metal clamp with holes in it that operates the subwoofers some how because it came loose and the woofers and the amp stopped working as well. I think that about covers it unless I have forgotten something which I will post if I remember. Anyway, I am happy that it is working now. Just need the carpet to sit flat again. The carpet on the sides does not fit right either.  .....I am trying to post the pic of my amp now. It will be up in a few minutes I hope. |
