5.0 out of 5 stars Polk Audio sub replacing Mark Levinson sub in Lexus LS430, May 3, 2009

The Mark Levinson (ML) subs in 2001 - 2003 Lexus LS430 are notorious for blowing-up very easily. Lexus ML replacements cost $350 - $400 (plus labor) ! ! :(

I decided to pass ML and instead went with the Polk Audio db840DVC sub which cost me less than $60 (inc. S&H) and installed it myself. Even though the ML sub has a 12ohm impedance vs the Polk at 8ohms (4+4), the Polk works great. I'd say it sounds better than the original ML sub :)

got this to replace a blown sub for my polk audio theater sub, turns out its was a little bit bigger then the old one, but after some fabrication. got it to fit and turns out the problem was the amp. rigged up an old car amp to it and does it hit hard. shakes the whole house, and gives off great sound. enough to rival a 12"

would recommend to anyone

I replaced my Mark Levinson stock subwoofer in my 2003 Lexus LS430 and it works great. Although I was somewhat worried about how it was going to sound not being in an airtight box, it actually turned out to be great. Also, the magnet was much thicker than I thought it was going to be. The stereo shop that installed my sub couldn't believe the price I paid for this. I would recommend this speaker for anyone looking to replace an 8" sub.
