Used this in a desktop 2.1 setup, build a 1.15 ft^3 box with a 3" precison aeroport tuned to 35Hz and it slams!! I'm powering it with a fosi audio TP-02 amp wired in parallel to 4 ohms i'm blown away with how much bass this little inexpensive 8" sub puts out.

Worked perfect on my LS430 with the ML system, make sure u wire it up correctly for 16 ohm and then mount it directly to the deck with a little padding maybe and some self tapping screws, no need to reuse the casing of the original sub. Works fantastic and is very loud! So worth it

I needed to replace a blown MTX sub and Figured I would give this one a try. I was pleasantly surprised by the performance especially at the price point. If i need another replacement home theater sub I will buy this brand again.

Sounds great! used to replace in my 2004 Lexus LS430 UL. had to modify it a little and make sure it was wired up properly to achieve the same ohms as the factory as a previous reviewer stated, or you can blow the amp.
