Right now I have a cheap Pyramid 4 channel amp bridged feeding a cheapo Lanzar 12 driver in a vented enclosure. I have an M Audio Mobile amp I could use, and I have been looking at the other stuff out there, like Planet Audio, Boss and Alpine (which looks the best so far). I think the M500 is the one...It's about $150.00 and has some pretty good reviews..I know I probably need to upgrade the driver too, but it's really not all that bad....plus it is in a car...subject to freezing and roasting in the baking sun. I really don't want to put a high dollar driver in the van to be baked..I'm also still using the stock head unit in the 2006 Honda Osyssey...I was thinking about going with a Pioneer just to get the 3.5 mm input..plus the obviously better sound quality and flexibility it would offer. What do you guys think? Anybody into mobile audio in a big way...Any budget minded mobile audio guys?
