I am a bit confused. Do I need a 8 ohm or a 4 ohm sub?
Right now I am running a ADCOM GFA-545II to my right and left channels. They are (in each box) 1 dayton 7" driver and 1 dayton silk dome tweeter and custom crossovers in each box. All the 4 speakers are 8 ohms.
I want to purchase Dayton SUB-120 HT Series 12" 150 Watt Powered Subwoofer

Does it matter if the sub is a 8ohm or a 4ohm? Will this sub work with my current right and lefts?

From the sub manual off the parts express website it says this about the outputs
Outputs:
There are also line level RCA outputs and high (speaker) level outputs.
The line level (RCA) output provides a full range (20-20KHz) output and
is used to connect “daisy chain” the line level signal to other amplifi ers.
Note: Line out is only active when a signal is present at the line-in input.
Speaker level outputs are used to connect satellite speakers. The
satellite outputs have a 12db high pass circuit (275 Hz @ 8 ohms).

ok great. I understand how to hook this up.
I want to have more control over EQ adjustments. Can I do this with a piece of software on the computer or would the forum suggest using a outside piece of hardware?
