[QUOTE="Nico Yazawa, post: 8619609, member: 674412"] Hi all! New to the forum and am hoping you guys/girls can steer me in the right direction. So it has probably been half a decade at least since I've really done much with car audio other than installing a few head units so I've pretty much forgotten everything I used to know. I'm hoping to get a little advice on what to do. I recently purchased a 2004 Lexus LS430 with the Mark Levinson premium sound and navigation. It has a subwoofer in the rear deck which unfortunately is partially blown and sounds really rattly. When I push down slightly on the sub, it sounds fine but I can't see any tears in it or anything. Anyway, I just want to replace it. I figured I would use this as an opportunity to upgrade a bit but I plan for it to be temporary. I want to replace it with a nice system later this year. I am not ready to upgrade my headunit yet as I will be doing a custom Android tablet with a DAC install. That is a summer job when the weather is nice. So I will be using the factory head unit for now. So I'm looking at buying a free air sub so I can just drop it in the deck. I will be using an aftermarket amp for it though. I have an old school Alpine 3555 sitting around that I would like to use to get some extra bump. I was able to find these specs on online: Maximum Power Output........................................500w total Power Output (2020 Hz to 20KHz, at 14.4v battery voltage) 4 channel mode: 50W x 4 (into 4 ohm with 0.08% THD) or 75W x 4 (into 2 ohm with 0.3% THD) 3 Channel mode: 50w x 2 + 150w x 1 (with 0.3% THD) 2 channel mode: 150W x 2 (into 4 ohm with 0.3% THD) Fequency Response.......................................... ....10 Hz to 50 KHz Signal to Noise Ratio............................................ 105dBA Slew Factor............................................ ................
