TLDR: Just as everyone has said before I tried it, there is no saving the stock subwoofer box setup
I have been replacing the factory speakers in my 2000 Land Cruiser. Replaced the door woofers and tweeters up front with Focal speakers. Applied sound deadening and foam surrounds to woofer locations and the result was mind blowing, much better bass response and crisper sound even with the factory amp. The only issue was I wanted more bass and the stock subwoofer was now grossly overpowered if it every did much at all. Decided to order the Dayton Audio TCP115-4 speakers that others have tried as drop in replacements for my factory 4" woofers. All my factory speakers are in mint condition, a benefit of cooler climates, but with how impressed I was swapping out the door speakers, I was hoping for similar results with the subwoofer.
The factory woofer speakers in the sub enclosure have a unique mounting plate so I created a 3D printed adapter for the Dyson Audio speakers that allowed them to bolt right up at the same height as the factory speakers so there was no issue with fitment both in the enclosure and with the panel covering it. Everything was looking good until I started playing some music...
These speakers were much "louder" than the factory ones, they push way more air. I could hear them clearly from the front seat. The issue is that they sound terrible. There was a resonance that I was assuming was coming from some other panels in the car due to the more aggressive bass response but when I went to hunt down the culprit, it turned out, it was the subwoofer enclosure itself. It sounded horrible with more air being pushed around inside. Thin and hollow with an annoying drone.
I’ll be trying a Kicker 46HS10 all-in-one under the passenger seat next. I’m not looking to shake my 23 year old car apart, I just want to round out the impressive sound coming from the new door speakers.
