[Pioneer EQ-6000 experience ?]

Hey guys, a friend at work gave me this equalizer the other day. I have only found manuals for sale online and I really didn't want to buy the manual if I wasn't going to use the EQ. I have a Alpine cde HD149bt for a head unit which already has a 9 band EQ on it. I read somewhere it can be used as a crossover for a sub woofer if that's the only speaker its controlling? Also was wondering what the D.A.B control is all the way on the left of the device?

[Pros and cons of hifonics]

Looking to purchase a hifonics amp. I see a lot for good prices. Will the quality be as good as the price? 250-400 price range.. Pros and cons of hifonics if any.. Does cea2006 mean anything?

[crossovers]

Where can I get like crossovers separate from my receiver. Like to power a subwoofer off one of the channels in my home receiver so nothing but lows go to it, no highs.

I'm looking to put a 10" in my room on a spare channel.
