What are you using for crossovers?

i run my front components off of an alpine 4 channel. the tweeters take up 2 channels and the mids use the other two. i have to run the signal through a 3 way electronic crossover because i am not using the crossovers than came with the set of components. is this something you are trying to do?

You must use crossovers. Fortunately your CDA-9835 has crossovers built into it. See page 15-16 of your owner's manual. The trick will be knowing what pass bands to set for your woofer and tweeter. DLS uses a 4KHz crossover in their component set using that woofer, so you are likely safe setting it as the mid band (rear outs) with a high pass of 80Hz and a low pass of 4000Hz, and using your tweeters as the high band (front outs) with a high pass of 4000Hz and hope the ones you've chosen can handle that. You'll need to use the gains on the amp to balance the levels.
