Best non-JBL line converter option

Okay so with these absurd prices today I decided not to swap out my head unit this year. I already have an amp, power wires, and speakers from my old truck so please help me figure out the remaining few items:

• I will need speaker "spacers" to install in the doors.
• I already have: Factory Amp Upgrade Harness
  $18 AHH-4438 2010-2019 Toyota Tundra (w/o JBL Audio) AutoHarnessHouse.com Factory Amp Upgrade Harness AHH-4438
  AHH-4438
• Line out converter: I need some help with this...
  • ********* has an NTUNE6
  • Tech12volts has a Scosche's LOC80
    

Are one of these LOC's better than the other? Is there anything else I'm missing out on here? THanks for any advice!

 

Audio Control has some nice ones as well.

 

I kept the stock head unit and speakers, just added a subwoofer. The

$92 Audio Control LC2i 2 Channel Line Out Converter with AccuBASS and Subwoofer Control

Audio Control LC2i "worked" for me but I couldn't fix the bass roll of below ~40 Hz, which I couldn't live with. I was thinking about the JL Audio LoC 22 (?) but decided on the JL Audio Fix 82, and now my limitation is sub box design. It's not cheap but does the job well. I'll sell you my L2Ci if you want to try that.

 

I have the NTUNE6. It eliminates the bass roll off.

 

Okay, and by the looks of it the NTUNE6 seems easier to set up than the Audio Control ones. I guess I'll go that route.

 

Lcq-1 from audio control

 

I looked at that one, it looks like it would be difficult for me to set the EQ portion correctly.

 

Welp, I purchased the NTUNE6 and it has way too much bass for me. I like country music not puff daddy. So I just bought the LCQ-1 you all told me to get in the first place. I'll try to swap it out tonight maybe TundraTex can swing by and help a neighbor out.

 

Well, how do you like the LCQ-1?

 

I like it a lot, a little intimidated by how much tuning is possible, but I left everything almost at default levels and it sounds excellent.
