63stick Posted 9 hours ago Report Posted 9 hours ago Getting ready to drop my dash back in and though I was going to keep original radio in it, I thought last night of changing it out. I don't want to go crazy as car is not going to be a daily driver but it would be nice to be able to listen to something other than talk radio over static. Any suggestions on make, model #. I'm not going to install anything that would require modifying the dash. Also speakers that mate up to existing mounting holes. Thanks
Gunslinger Posted 5 hours ago Report Posted 5 hours ago Is the static you hear a constant tone or does it go up and down with engine rpm's? If it stays constant it's ignition noise. If it increases and decreases with rpm's it alternator whine. A condenser in the proper place may take care of it...just need to know where. You can also mount a noise filter in the power lead to the radio. Other possibilities...the antenna itself may have lost ground...make sure it's properly grounded. There's usually a wire from the antenna to a bolt under trunk carpet that's grounded. Also the radio may need the antenna "trimmed"...a lost art few today are aware of. To trim the antenna...remove the right knob on the radio and you'll see a screw above the shaft. Tune the radio to a station...fairly strong...around 1400. Then using a small screwdriver turn the screw until the radio gives best reception. Once you get best reception and sound the antenna is trimmed. You can also spray some electronics cleaner inside the radio...I've seen that clear up noise problems before. If this fixes things you're good to go without buying a new radio. If you feel it necessary to replace the radio...look at Custom Auto Sound. They should have something that's drop-in for the car.
Gunslinger Posted 5 hours ago Report Posted 5 hours ago Something else...does your car still have the RFI shielding over the distributor and spark plug wires? If not that could be the source of the noise. Fiberglass has no natural RFI properties and shielding is needed. Spark plug wires could be the cause as spark plugs could be as well if not shielded or resistance rated.
63stick Posted 2 hours ago Author Report Posted 2 hours ago Gunslinger, Sorry, I was just kidding about static, talk shows because there is nothing on AM that I would listen to. Had been going back in forth about upgrading the radio. I like my car original, It still has the original Stereo magic Reverb in it the dealer installed when it was new. and as I mentioned in post, it's not going to be a daily driver. I overhauled the original radio and it works fine. I just thought that now is the time if I am going to upgrade or it won't get done. Once I drop the dash back in, I don't want to go in there again. I also don't want or need to spend a lot of money on a head unit if I don't need to. My hearing is so bad, I don't need really good equipment. I am not cutting anything out to add speakers. If I could find a rear deck, I would, I did find one but they want $150 shipping. I would probably be better off to use mine for a templet and make one. I have a roll of the original viny that's doing nothing but collecting dust and making a home for mice. Any speaker that you know of that fits the front. Thanks
