Kenwood X802-5 eXcelon 5 Channel Tune

A couple of question for the Kenwood Amp.

1) Do I flat line my 2021 Tacoma stock Head Unit equalizer before I tune the input sensitivity / Gain, with a multi meter on my Kenwood Amp.

2) What is the best way to tune my SUB LPF Frequency and the best way to tune my HPF Frequency on Channel A and Channel B

Thanks for all the help. I appreciate it.

 

1) Yes. Turn off all processing in the HU prior to adjusting gains.

2) Put output switch to A/B for sub.

Adjust crossovers in amp to desired settings, (ie. 3200Hz for tweeters, etc). I THINK that amp has a 2/4 ch input switch, set to 2 channel, and use L/R of amp A for mids, L/R of amp B for tweeters. Sub will sum output with switch setting above.
