In the dash- factory AM radio, I think it works...
Under the dash- '70's Pioneer Super Tuner AM/FM 8-Track, period correct, installed by original owner. ( I just picked up a cool "alligator skin" case with 21 8-tracks for FREEEEE from craigslist.org.
)
To be put in glovebox or under seat- Blaupunkt AM/FM Casette deck, period correct for late 70's/early 80's (I got 2 big crates full of stuff from craigslist.org, 2 Blaupunkt head units, big amps, ADS speakers, etc.... for FREEEEE!!!!) For the old Van Halen cassette tapes...
One of these days I'll catch up to technology....
Newer 6x9's out back with Jensen Triaxial speaker covers. 4" rounds up front. Will try to make center speaker in dash only for AM radio or add an a-b-c swtich so all radios will work with existing speakers.... one day....
I'll keep perusing craigslist.org for free NOS Challenger parts!
