MA Audio; Good subs/amps?

I've been lookin for subs to put in my Ranger, since it's not extended and I'm 6 ft there isn't much space, but I can fit an 8 inch sub in between driver/passenger seats so I've decided on that, but what I'm getting to, is have any of heard or use MA Audio, I know a guy nearbuy that just opened up a shop and has some MA stuff. What I'm looking at is an 8 inch sub that's 400 watts rms, and the amp is a 400 watts rms @ 4 ohms, so looking at it it looks good, I can't remember all specs on it so I'll try to find the website again, but the sub was only $90 and the amp $190, that's damn good price I think but I'm just not sure what quality they are, I figure if some guy sells them in a store then they're not a major rip off, then again........

I've heard good and bad from MA audio, I have a few suggestions on subs though
Diamond Audio CM3 08D2
Rockford Fosgate RFD2208
Audiobahn AW800Q or AW831T
the last two subs are weaker, so they are only suggested if you don't need too much power.
JL makes some POWERFUL subs too,
8W7

I think MA Audio is some pretty good stuff, with cheap prices because of their lower overhead.
