    Avanti Radio Static?.....Modern Radios

    Time for a Radio upgrade in my 79 Avanti II.....talked to a guy in a automotive audio shop about upgrading to modern AM/FM (w/blue tooth) in my Avanti.....he said that the modern units do not require the shielding to prevent static issues in fiberglass bodies....is he correct ....any experiences out there.....?

    I have an Alpine AM/FM/CD player in my '70 Avanti and no ignition shielding...no ignition noise at all. I think it comes down to buying a quality stereo and you shouldn't have a problem. I would advise to not buy a Custom AutoSound unit as they're not of the best quality and probably have little to no filtering capability.

    I've had my radio on my '63 Avanti R2658, rebuilt by Bill Newman, "Bill the RadioGuy" in Shelton, WA. He chipped it to play MP3, Blue tooth, iPhone, and FM. It worked perfectly once. Sent it back & he did it again. Works outside of the car, but once installed., NADA, Silencio. You can hear that it's energized and I've traced the antenna, the power, everything but no sound. I apologize if this is considered "highjacking" but anybody have any ideas?

    It's possible you have so much RF noise present that it has swamped the front end of the receiver, and AGC has cut the receiver gain to essentially zero. I would also look at the antenna and its cable.

    If one changes out the radio in an older car the speaker(s) MUST match the output impedence required by the new radio. Older speakers were 10 ohm. New radios require 4 and sometimes 2 ohm speakers. You will fry the output transistors of your radio if the impedence is not correct.

    I had Roy Yost (Radio Roy) convert the '63 Avanti radio a couple years ago and it works perfectly, without any shielding or with it. Maybe the workmanship or conversion parts used is suspect. I have nothing but praise for Roy's work! Bill

    I'm out of town at the moment. I should be able to check the model number once I'm home on Monday. I also had installed Alpines of a similar model in a '69 and '78 Corvettes I owned without noise issues...but both those had shielding where my Avanti doesn't.

    I have a Sony unit in my 83 and a Chinee double Din video unit in my 74, both with Pioneer speakers. I use good speaker wire, the engines have resistance plugs and wires and electronic dissy's with no points. I get local AM, which I don't listen to much and FM without inteference from the engine. IAH, I haven't driven the 74 much but the 83 has seen a few miles. The antenna's are glass mounted, amplified ones.

    If that's his recommendation, then come to an agreement on price installed with the agreement that it needs to work as described then drive on enjoying your tunes. There's a fair bit of knowledge about interference these days so let him demonstrate it.

    Personally, I don't plan to be able to hear much over my exhaust on my 74 but that's just me.

    It's an Alpine model CDE-9874. It's been in the car for ten years or more so it's likely been superseded by a newer model.

    Thank You....I'll search for one. Is it in-dash unit?

    There are marine "black box" stereos, that mount remotely like in the trunk. Only the remote control is placed somewhere to control it. (like in the console compartment, or ashtray).

    Here's a pic of the Alpine in my Avanti. The opening needs to be modified as it has no knobs and a filler piece had to be fabricated. It was done over ten years ago when the car was being rebuilt and the dash was out. I would think removing the dash is the way to go with this modification. I have seen Avantis with a new type radio installed in the console where the a/c evaporator would be but obviously it has to be a no a/c car.

    notice comment on their website "after you've checked all grounds". your pro tuner upset a ground connection- or put in a bad capacitor

    Things for them to check
    -evidence of sparking inside the distributor cap
    -plug wire shielding not grounded properly
    -Is the noise coming from plug wires or alternator?
    -radio poorly grounded
    -antenna lead shielding bad or antenna plug loose or corroded
    -proper type of plug wires
    -distributor cap and rotor are a matching set? I have seen Chevrolet caps and rotors of two different heights. Putting a low rotor inside a tall cap made the spark have to jump way too far. Putting a tall rotor in a short cap would immediately break one or both parts.

    You should print out this list for them, to make sure they hit it all.

    I was reading your post and answers to your string "Why do the Studebaker gods...." and looked up your history and came up to this post. Well, I had a 63 Avanti R2-4212 http://www.studebaker-info.org/AVDB1...x07052017.html for 20 years starting around 1992 and replaced the speaker about 5 years later [Studebaker gods must have had a hand in the installation difficulties] and as I recall, had only minor problems with ignition noise. Of course, I could not hear radio when the car was running on the road because of engine/supercharger noise, and it was too hot to drive in the summer unless windows were down and going 60 mph, and again, wind noise plus above engine noise....etc . Finally sold it around 2012 for exactly the same price I paid for it in 1992 [$12,000] after spending about $500 per year in expenses [12 sets of spark plugs, one set of power steering hoses, deteriorated rubber gas line connector to fiberglass gas tank, removing & cleaning tank, brake disks and shoes, etc.]

    This gets me to my 64 Avanti R1-5213 http://www.studebaker-info.org/AVDB1...5213x0914a.jpg with factory air, and of course no supercharger. The radio worked well until it quit, and then I decided it was not worth the effort to remove the air conditioner unit to remove, repair, and replace the radio [and probably a new speaker]. Maintenance expenses were just about the same as on the R2 except it doesn't foul spark plugs and no problems with gas line [yet] but I did have a $10 electric fuel pump put in adjacent to the fuel tank, and I have not had to tune it like the R2, which never seemed to run right the high altitude [over 5,000 feet]. I replaced the stock mufflers with "Holllywood glass packs" which are so loud I don't miss having a radio.

    You could consider just using your smart phone with ear buds and stream your music or listen your collection on the SD card on your phone.

    Ear buds are dangerous to use while driving and are illegal in many states. They should be illegal in all states.

    I agree with Roy....that's not the solution for me. The shop that did the tune-up has hired a new "electrical guy" and a new service manager.....they have agreed to check it out again....hopefully "fresh eyes" will help.....

    What does the shop say? I imagine more than one of us is curious as to the solution.
