New radio wierdness

Hi all,

Was hoping to get a little input on an issue I'm having. I have a 69 Chevelle..388 sbc, th350, 12 bolt etc etc...bought new pioneer 6x9s and 4x6s, and a Ken Harrison radio. Radio has presets, RCA outputs 300 watts's the problem.

Hooked it all up per directions. 12v constant, 12v switched, and good chassis ground. Unit sounds killer until I start the car, then it cuts out completely, then starts making some nasty loud static type noises..hard to describe...its not like when you get alternator feedback noise..its very erratic and nasty sounding..

Talked to Ken Harrison and he seemed to think it had something to do with my HEI dizzy causing interference, and recommended I get 12V sources from somewhere besides the fuse block.....haven't tried anything yet as I've been busy...but was wondering if anyone else had this kind of problem, and if so how did you solve it?

Thank you!!

I'd run a temporary wire directly from the battery to test it.
Then start the car. If the HEI is the culprit, then find another hot source.

Re: New radio wierdness

The above is a good starting point. A voltage drop maybe occurring and the radio "cuts out" intermittently.

Radio "goofy-ness" can be caused by power supply issues or RFI (noise sent thru the air radiated from ignition components and electronics or a combination of both.

Unfortunately Ken Harrison and Custom Auto Sounds rank at the bottom of the barrel as far as quality and reliability goes. Try the power trick first and let us know how it comes out.

Any luck resolving this? I have a Ken Harrison that just started this issue.

Re: New radio wierdness

I have had the same issues with a few repo radios, ignition noise.. I've given up on them and just use the stock Delco AM with either the Redi Rad or I solder an input into the volume control.. The stock Delco sounds excellent with the correct 8-10 ohm speakers, turnswitch sells new ones.. The quality of the old Delco is light years better than these repos..
