I don't remember years and whatnot either - just that I have owned these at one time or another:
(2) Pyramid Super Pro SVC 10s in sealed boxes.
(2) Clarion 12s in a big-*** 'truck' box that had the spots for the 12s firing forward into the back of the seat and each end had an angled, top-firing spot for a 6"x9".
A Kicker Super II prefab enclosure that had two forward-firing 8s and two 10" bottom-firing passive radiators (remember those, Polecat?)
Another Kicker prefab (truckbox) that had a pair of forward-firing 12" Comps with those Motorola horn tweets in the top of the enclosure
(2) Pioneer IMPP 12s (they were black - don't remember the model #)
(2) Rockford Fosgate Series 1 12s
(2) Rockford Fosgate 'The Punch Classic' (semi-inverted dustcaps) 10s that my ex-landlady now has in the back of her Camry.
(2) MA Audio SVC 12s (don't remember the model - whatever the bottom-end sub was that year - got 'em from
eBay for $80 then another $45 for a sealed dual-12 enclosure...ran 'em for exactly a day and sold 'em the following day)
(2) Kenwood eXcelon KFC-Xw10dB SVC 10s....these now serve HT duty wired in series
(1) Diamond Audio M6mkII12D4
