Another thing to Jazzy's benefit. I've almost completed an install of no-blank-cd aux, where I've tabbed between the radio and the amp. If I knew how much time and effort it would've taken, I'd simply used Jazzy's board. Yes, jazzy's board has a pause every 90 minutes when the blank CD ends, but he does not have thumps that I have. His way requires 10 times less time and no skills in electronics. If something goes wrong with the stereo, simply remove the board and no dealer would be able to say that the warranty is waved.
