Kenwood KAC-8405 Amp help

I just recently got a kenwood KAC-8405. Now I got two questions:

A) What should i have the hp/lp frequency set to for best results?
B) How would I be able to wire a sub into the amp?

All speakers and the deck sound alright, but I feel like it's a little muffled. I know its not the EQ settings on the deck so it must be the amp but I dont want to blow all my fuses in the process.

I have all my subs set up and ready to go but I dont want to drop another $200 into a mono amp because I was told this amp would be able to hold all 4 speakers and well as my box.

Help???

If it helps at all that a 4/3/2 channel amp, with 720w max.

If it's sounding muffled then try adjusting your LP (low pass filter) & HP (high pass filter) frequencies. It might be that your LP is up to high or your HP is too low. The easiest way to set these is to borrow the help of a friend. Sit in the drivers seat with the volume at a level that you usually listen to and with music that you typically listen to and both the LP and HP pots (dials) set to zero (or 100% counter clockwise). Then have your friend slowly start adjusting them until it sounds best to you.

Sadly, the KAC-8405 is a stereo amp and is not designed for subs, hence the 4/3/2 (4 speakers, 3 speakers (one channel bridge), 2 speakers (both bridged). I would not try to run subs on that amp in risk of destroying something.
