Tried some high level inputs vs RCA today
Yes, I cut the RCA ends off the input harness to the amp and soldered HL wire on to it, then soldered the HL wire to the speaker outputs coming from the HU.
Was your HL gain setting in HP or AP mode? Did you notice a difference in volume and gain settings for the onset of clipping between the two modes? I ask this because I'm currently using a T400x2AD in AP mode with HL inputs from the stock Harley HK head unit. The sound appears to be fuller in this mode rather than HP (with better bass), but I'm wondering if I might be sacrificing the high end some with this mode rather than HP?
If your bass is coming in fuller on AP than on HP, I'd ask what you what hz you have the HP filter set on and what speakers are you running to determine where you should set them.

Unless I am running subs I run HP on everything. Although, as Haze said, it won't matter b/c the test tone is a 1khz and will go through either way. It would only be knocked out obn LP.

Depending on the speaker set up, I don't have a single speaker on my bike on AP.

so, in theory, every hu, amp, speaker, and speaker "compartment or location"combination will sound different with HL and LL applications? you guys make my head spin🤓
gets me to thinkin... if it sounds good to my ears at 80mph and doesnt break my bank......love readin all the tech articles. i havent done any audio mods since high school. thats right... when you turned the radio **** and the little needle moved across the number line. hows that for tech? i did get a slight insight on EMI reduction from a friend of mine. will soon be installing a couple different class d amps in 2 diff bikes with 2 diff head units. if i get good results i will post

As it appears you are new to all this so don't be to concerned with high level and low level connections. As long as the amp you choose has low level connection use them.

Yes, there are a lot of factors to take into account when putting a system together. That's with the folks here will help you with.

Does the Aquatic have RCA's on the back for front and rear speakers? If so those are your low level outputs that will connect directly to the RCA inputs on the amp.
