Retro Sound radio cuts out

Alright team I am at a loss now in regards to my retro sound radio that I have installed in my 71. Everything works fine under idle conditions. In fact it sounds great. The issue I have is when I go to accelerate the radio will cut out until I am stopped with the car at idle again. I have checked to make sure the radio is properly grounded as well as added the grounding straps from the motor to firewall and the firewall to the frame. I am running an an accel hei distributor as well as I have swapped over to the internal regulated alternator. What else should I check in order to get a constant jam while I cruise? Thanks for any assistance you are able to send my way.

Re: Retro Sound radio cuts out

Run new but temporary power and ground wires directly from the battery. Then go for a drive and see what happens. If your radio runs ok with these, disconnect one of these temporary wires and go for another drive. These tests should reveal which half of your power circuit has the trouble. Fix that.

Re: Retro Sound radio cuts out

You are getting RFI from your HEI distributor, Retrosound radios are notoriously bad for dealing with it. You can try some radio frequency chokes around the power wires, which will help, but not cure it completely. Retrosound tech support solution is to relocate the radio body to a location further from the dash and the distributor, they sell a relocation kit. I had the same problem in my 72, ended up ditching the HEI and put a Pertronix module in my original distributor, I have no issues now.

Re: Retro Sound radio cuts out

I have a similar problem with my retro sound unit. Mine works fine until the rev's drop low and sometimes it cuts out. I thought I had a bad connection and haven't had a chance to chase after it. I have the crane XR-i electronic ignition.

I'll be interested to see if there is a fix other than relocating the unit.

I tried these, and they helped with the radio cut out, but it didnít cure it totally. Maybe you will have better luck.

I used those on mine , it worked, my radio worked fine though, it was the USB playback that would stop & start.

Re: Retro Sound radio cuts out

I've had number of problems with my retrosound that started almost immediately after installation. 6 months later and it's sitting on the shelf, collecting dust. Nothing but issues and no help from manufacturer.

To suggest relocation of the unit that was bought for the sole purpose of replacing an original unit in the dash and retaining original look, is ridiculous.

Sorry to say but they took cheapest Chineseum units, slapped a retro face and they are selling them at premium price. Their tech support can't even spell CAR STEREO, let alone help you with a problem. Even my $30 media player that I bought on Amazon has outlasted retrosound. I fixed mine by taking it out, and installing Alpine with all the bells and whistles, including hands free phone.

Re: Retro Sound radio cuts out

another strike on retrosound, I stopped recommending them a long time ago.

Re: Retro Sound radio cuts out

I've had a Retrosound for awhile and have HEI and have had no problems with the combination of the two. What I have had a problem with is that the installer neglected to use the supporting strap in the back and the unit just flopped around, causing one of the wires to short. I supported the unit with a cork shim underneath as it's really crowded back there due to also having Vintage Air ducting behind the unit. Every few years or so, the cork compresses enough that the short comes back, and I have to shim it up again with a penny or two and some electrical tape. It just happened recently. Check your wires to make sure that they aren't pinched or stretched. Maybe drive slowly while playing the stereo and move the wires around; maybe you can isolate the problem.

One of these days I need to get under there and support the unit properly with a metal strap -- that's what I said about five years ago.

Re: Retro Sound radio cuts out

I installed a input jack to the stock Delco AM radio and I'm real happy with it.. Those after market radios are hard to hear with all the noise that comes with one of these old cars...

I was told by a audiophile that GM engineered the Delco radio with the interior noise in mind, that's why it has such a deep mellow sound to it.. He recommended I run a small Blaupunkt amp after the radio and a couple speakers for more power. It sounds fantastic for what I have into it!!

In my '70 Chevelle, I hate to tell you this, but, I went through 3 of these stereos. They are cheap chinese junk. I ended up with a replica from Antique Automobile radio from Palm harbor, Florida. They are made in the USA with quality components, but, they are expensive and they have a waiting list. They come with a nice amp for the front speakers and I use a separate amp for the rear speakers. It sounds great and there is no interference. The blue tooth works awesome with my iphone. It looks original and the tuner face flips from AM to FM just like the original. It is really a quality piece worthy of my Chevelle. This is what I paid for the '70 SS replicate stereo. It is a lot of money, but, I wish I would have known about it years ago - instead of spending $200 on chinese stereo crap every few years. Good Luck with it.
