3rd Gen Tundra With JBL Sub Addition

Posting this in here in hopes it may get some direct attention as it’s related to audio enhancements. Any help would be greatly appreciated!!


Hoping for some help/guidance/input here.


I have a 2025 Tundra Limited with JBL. While the system is much better than in my 2021 Tacoma, I wanted to try and get a little more out of the entire system; highs, mids, and lows. I have purchased the following:


-Beat-Sonic ENA-3T3: this is a simple plug and play amp for the factory system. 50x4. If you look it up, ignore the RCA outputs. I talked to the MFG and using those RCAs with the JBL system will not allow the aftermarket sub to turn up and down with the radios volume knob.

-JL Audio ACS110LG-TW1: this is a powered 10” subwoofer with built in 400w amp. This has both high level and low level inputs.


My plan is to use the ENA-3T3 to get a little more “umph” out of my entire factory system. I know this, alone, will not enhance the system in any huge way, but figured it was a simple, plug and play, way to get a little more from the stock system.


In addition, I plan on installing the JL Audio ACS110LG-TW1 as a self powered sub to get additional bass. Again, I know this will not be anything crazy and ground shaking; that’s not what I am looking for.


So, questions/touchpoints:

1. Does our system have “bass roll off” like previous models?
2. The Beat-Sonic amp is completely plug and play so I am good there.
3. For the JL Audio powered sub, should I use high level (directly from speakers) or low level (RCA) input?
4. If using high level, where should I tap the factory speaker wires? At the headunit and before the factory amp? After the factory amp? Or before the factory subwoofer? Regardless of the suggestion, why do you suggest that?
5. Same question as above, but if I use a LOC?
6. For the tapping portion, based on your suggestion, can you provide simple wiring colors so that I know which to tap from? I’m not the best at reading wiring diagrams unfortunately.
7. If I use an LOC, would a simple passive LOC be sufficient such as the Kicker 46KISLOC2? I know there are better, active, LOCs, but if that is not needed then I would rather keep things as simple as possible.
8. If I do need an Active LOC, can you make a recommendation?
9. Where can I tap factory wiring from that will allow me to control bass from powered sub with volume knob on stock radio?
