in measured sealed MDF enclosures and 3 sets of MB Quart components powered by four Rockford amps and tuned by a Rockford EPX2 crossover in my Z. Not to mention all of the 1 gauge power/ground, 10 guage speaker wire, and 9 sets of Rockford RCA cables. About 5 grand all together. I can email you pics if you'd like. After a year I got tired of it, sold it all for less than .25% of cost. I now hear my tunes through an Alpine head unit powering two sets of 5.25" MB Quart coaxials. It rocks. My car, my brain and my neighbors are much happier. My wallet still suffers some trauma however...
