I am currently using this memphis 1000d amp to power my 2 diamond m6 10 inch subs. If you want any info on any of these products then just let me know. Both are in excellent condition with no damage what so ever. They both look practically new because they basically are. I never played my music really loud on any of these and i believe on the subs the surround is still firm. I cant really tell right now because i have them inverted which looks awesome because of the chrome and all. WANT ANY MORE INFO EMAIL ME everclea13@aol.com
