So new stereo setup is installed, now on to the fun part..... tuning. I think I understand the basics after some YouTube videos, but would like to get some feedback from someone who has more experience than me. Including pictures of everything so that you can see what I'm working with and where my thought process is. Not trying to buy and tuning devices, just want to get it as good as I can by ear without damaging parts, so here goes.

I have the 255 FSH, and replaced the stock 6.5's with Kickers, specs below.

Powering those speakers is a Kicker 6 channel, specs and controls below.

I'm only using Amp 1 for inputs, because each of the 6 is getting the same exact inputs and I want them as 1 zone. I don't know what to set the "input level" knob to, so advice there would be great. For amp 1 settings, I think I just set my volume to 75-80% and turn the gain up until the music distorts, then back off a little. My understanding of the freq setting is the I should set the x-over to "HP" and because of the specs of the speaker, set it to 35 hz. Is that correct?

Next on to the 8" tower speakers

and 10" subwoofer

Both of these are powered by a 4 channel amp, specs and settings below

The 8" tower speakers will be zone 1, and the sub zone 2.

I'm a little lost on what to do with the tower speakers. Being that they are larger than the 6.5's, I would think they have the capability to go full range, but looking for input on that. Since this amp only goes down to 32 hz and the speakers are rated for 30, I believe I leave that all the way down. Same process as the 6.5's in regard to gain.

For the sub, same process on the gain. Set to LPF, and turn freq all the way up since the sub is rated for 500 and this amp only goes to 320. Side note- I bridged 2 channels on this amp for the sub and I am aware that the sub is rated for 400W RMS and that bridging puts out 440W RMS. Definitely don't want to blow the sub, so thinking maybe back the gain off a little more than I do on the other speakers. Thoughts?

I know it was a long post, but hopefully I provided all the info for some good input. Any thoughts are greatly appreciated!!!
