2 10 inch PG titanium subs and a Interfire 2200 amp. I might switch the amp out with the MTX 81000D in my tahoe she like that amp better and i was planning on replacing it any way. I know the Interfire is not like a great amp to brag about but its 2000 watts and my friend who owns a shop had it in a demo vehicle for 3 shows and gave it to me for 200 when it normally goes for 550 so i could pass it you know
