I have a JL sub sitting in my house because I am happy with the factory ML set up now.

But you would need a mono amp, sub, enclosure and a 2 channel line out converter.

I wish you could hear my setup, as I think 1k watts is overkill. I had a 1.2k watt vacuum tube mono amp in one of my cars years ago, pushing an 8W7AE. I honestly can't tell the difference in my current setup. Some tracks to sample: Revolution by Diplo - My sub hits the 20 hz "brown note" that the ML sub can't even touch. Royal by Lorde - absolutely tight, jaw dropping lows. Shotgun by Yellow Claw - can feel the bass hit in your chest.

What I love about my setup is that the bass is not only excellent, but not one rattle anywhere..... My Son has some ridiculous setup in his Kia Soul (which sounds pretty good) and he's jealous at how good my system sounds.

I added the JL Audio ProWedge TW3 powered by a JL 300 watt amp to the ML system and the result is nothing short of amazing. Tight, accurate bass that does not overpower the system, but rather compliments the current speakers. I had it professionally installed, and the installer gave me the option to unplug the existing sub. What I did instead, is left the existing sub plugged in, but turned the bass down on the system and up on the JL. This gives excellent bass response without the rattle that usually accompanies stock subwoofers. I would not bother replacing the existing stock woofer, as it won't make a difference in the sound profile. The space is too tight for good air movement and it will likely be a pain in the *** to get to everything.

Finally, I thought the same thing in #3 above and swapped out the front door speakers with Hertz Hi-Energy 6 1/2" coaxials (excellent speakers by the way). The result was disappointing. The issue is that the 6 1/2" woofer does not move as much air as the current 6x9 stock ML speakers. There was a significant loss in mid bass punch. The sound was slightly more transparent than the stock speakers, but the loss in bass was significant. I took them out and put the stock ML's back in and have been happy with the whole system.

My advice is to install the JL sub with a dedicated amp. This setup is by far, one of the best I've had in any vehicle I've owned. Very neutral in the highs and nice punchy mids.
