how to adjust crossover???

[Italia30]

I have a Kicker ZX650.4 going in to Polk DB691, DB 651, and Polk Tweeters. I am new to this, Im am getting mostly midbass and highs,...no low end at all!!!!!........the amp has adjustments for XOVER-Hi-Low-Off(set to high), Input Level-Hi-Low(on Low), and X-Over Frequency 50-200 with four increments in between....any advice on how to set this up for a system without a sub???

set yuou xo to full range or off. do you know the pre amp voltage of your head unit? this will determine the input setting.

if you want full range sound frome your speakers, then set the xo to off.

with 2v pre outs, set the input to low.

if you want to hi-pass your speakers, set it to hi and set the xo fq to what ever sound good to you.

with the xo setting on off, you will not need to use the fq adjustment.
