I have an Alpine CDA 7838 with 4 channels of both preouts and spkr outs, and am wondering if there are any Alpine gurus out there who might know if I can use 2 channels of preouts for the front and 2 channels of spkr outs (aprox 40W) for the rear. I seem to remember someone, somewhere saying that you can choose one or the other but not both. There is nothing about this in my manual or installation guide and I cant seem to get any response from alpine. Anybody?
older units allowed you to use either pre-outs or power by selecting on teh unit in back via a switch. more current models allow you to use both pre-outs and powered outputs at teh same time.
