I have a DSP-408 that should be here tomorrow and had a question if anyone could offer some insight.

I have a 7.1 Denon AVR 3801 Receiver with Ex multi channel inputs Could I hook up the DSP outputs to the Multi channel in on the Denon be all set or would I need extra amps?

I'd like to start messing around with the DSP just so I could try a few builds with drivers I have on hand, I'd like to eventually learn how to build passive crossovers but feel it will take some serious time to learn everything and this way I could start tinkering now and at least hear some different drivers and have some fun.

Also when running speakers active will the tweeters need caps for protection? If so what size cap would I need?

Thanks for any help.
Dustin.
