I fired up the complete carputer install today. Using M1000, full size DVD and HD, and a 150w AC PSU. Im using the 12v rail to power the xenarc. I decided I would use the same wire supplying 12v to the Xenarc to power the amp. When I booted up, the Xenarc worked fine, but the amp would not power up. When I put a voltmeter on the remote line, I only got 8v. Is the Xenarc drawing too much power to turn on the amp? I guess so the amp runs fine when I connect the remote line directly to battery.
Would the best way to deal with this be simply using a relay connected to the 12v of the PSU and the battery? Id use the power supplied here to power the Xenarc and turn on the amp. any thoughts?
