Phantom Audio

Customer goal: Have an OEM ‘69 Dart radio function just as a Bluetooth receiver, but turn the system on and off as if it were OEM. Challenge accepted. Cleaned up an OEM radio, installed an Alpine BT module that fed from the OEM on/off k**b, as well as the acc wire for the amplifier, added RCA outputs, plugged it into the OEM car harness and all is done. Fun little project.

This wasn’t a bad little build.

Customer Goals:
Keep it as stock looking as possible
Strong SQ
Reuse a pair of non functioning, partially corroded PPI amps.

I started with rebuilding the amps: upgrading the opamps (Burr Brown, upgrading the caps and replacing the bad fets.

Next to figure out where to put the amps. Coincidentally the underseat storage was perfect for the 404.2 (on the smaller side) and 600.2 (on the longer side) like it was made for them. So we set the mounts, stretched the fleece and made the mold.

While the amps and rack were off to paint we deadened the entire vehicle with Stinger Ultimate, ran all wiring (highly recommend stinger 9000 series on your wide bands) and got the sub box together.

Once everything was back from paint and ready for install the fun began. All wires in all locations were either ran with oem harnesses or secured to the body, this helped a lot come install time.

Overall it was a pretty clean install with no real issues. The sound stage is phenomenal, floor level and system dynamics excellent. We ran an AudioControl RTA to get an idea of what needed adjusted. After a few tweaks we found Fq to be extremely proportional to each other with no brightness or dullness. The musical quality was extremely natural and dynamic with tonal accuracy dang near perfect. We were able to hit north of 110dB with zero distortion from the drivers which sounded just as amazing as normal listening levels. Attack and decay was surprisingly accurate for an oem source. The audio made the interior of the vehicle seem twice as large as it was with phenomenal realism.
Definitely pleased with this setup.
