My 1969 Corvette restomod AV-build amp problem

[Andy McKoi]

Hi,

Working on a 1969 Corvette restomod. Car is almost complete, on agenda for this winter is the audiosystem.

Wanted to "cold run" the system outside car before installing it but run into a problem. Can't wake up the dsp/amp (Match UP7DSP).

I have a fresh car battery with good voltage. Dsp/amp connected to the battery and measured that voltages are fine both at the battery and at the dsp/amp terminal.

Hot wired the "REM" (wake up wire input) from the + terminal. Again measured and the voltage there is fine about 12V.

Yet, the dsp/amp is not waking up. Opened the case and the two fuses inside are intact.

The LED indicator light on the amp does not lid up no matter what I try and the PC with the adjusting software for the dsp does not recognize the anything would be around for a connection.

Any ideas? Good it just be a dead dsp/amp or any tweaks one might try?

Thanks in advance!

Measure for 12v+ at the amp's 12v+ and remote terminals.

If I was having issues pre-install, I wouldn't take a chance with it. Can you return it or is it still under warranty??

Make sure the auto remote feature is turned off

The auto remote will only turn on if it receives signal from a head unit.
