The Boss REV 2000D is actually a lanzar vibe 1200d in a different heat sink, an interesting little tid bit i learned a while back. The Lanzar OPTIDRIVE series is pretty good im told, they perform well for the money.
For subs I would suggest the ECLIPSE 8700 series, they are the series just below the aluminum subs, I owned a pair of these subs and have yet to find a sub that performs as well for the money. They hit like a mofo and play as clear as a bell.
Eclipse 8712
XMAX-18mm(1.5inch peak to peak)
RMS-300watts(will take 400)
BOX-Sealed .8 to 1.3cft
SENSITIVITY-88db
CONE-Pearl mica polypropylne
she's a good sub and cost alot less than the aluminum cone versions, i would compare it to the audiomobile MASS 12 sound wise. Stay away from the 8600 series of subs because they will blow if abused( my 8700's withstood 400watts rms each for a year with no probs, some criminals got em now I really miss those subs)
I'm running a couple of MTX thunder 8000's right now and they perform alright but they don't compare to my old Eclipses, even with an extra 200watts to each sub(1200total).
