I recently upgraded the subwoofer in the RX. The factory sound system is very underwhelming. I built a custom enclosure and added a 10” kicker subwoofer. Sounds so much better.

 

Are you running an amp or using the factory one?

 

Im running a separate Kicker amp. I get signal from the factory subwoofer that way I can control bass using the factory equalizer.

 

I wonder if we can replace the sub speaker inside the same enclosure? Would there be improvement with factory Amp?

 

I doubt you could use the factory enclosure. It’s a radiator style sub from factory. And the amp would be too underpowered to push an aftermarket sub. I thought about building a box to replace the one in the factory location.

 

where did you install the amp at?

 

It’s under the spare tire equipment tray. There was some unused space under it.

 

what does this do to warranty? Have a spare sub but very wary of fiddling with wiring on a brand new car. Thinking of selling the sub.

 

My 2025 hybrid has its 12v battery in that location. I got all excited until I popped the trunk. Bummer

 

Shouldn’t have any issue with your warranty. I just tapped into the factory subwoofer wires for signal.

 

yeahhhhhhhh. I had a couple PM me and I gave them the bad news.
