OK, i picked this up for free from a friend and i am going to run my entire system off of it. MY HU is active capable and i would much rather run everything off of the HU. On the back of the amp there are 4 slots with switches behind them. I understand the top and bottom right ones, but i am kind of confused on the other two.

By Bypass and Lowpass or Highpass and Bypass, does bypass mean full range? That is what i want to use in order to run active on my hu, so i would switch it to bypass for all three on the left??

I want both on the far left to be on stereo because i am not bridging anything correct?

On the far left, there is a 3&4ch or 1&2 ch. What is this? If i switch it to bypass this swtich doesnt matter, right?

If someone could varify what i said or just tell me what i would want to turn the switches to in order to run fully active off of my HU only i would greatly appreciate it.

 
Yes, Bypass means full range so use that if you aren't using the built in crossover. And you are also correct using stereo if you aren't going to run it bridged. The 1&2, 3&4 switch is used to select where channels 3 and 4 get there input from. If you are running RCAs to the input of those channels, and it sounds like you are, select 3&4.

Here is a link to the manual. 405
