Posted March 22, 200817 yr I bought the sub back in early December, just got it installed tonight. its in a 2.4cuft box tuned to 32hz, powered by my "1500" watt hifonics amp. knukonceptz 1/0 KLM power wire to the back, also big 3 done with it also. after an hour driving around back country roads there was only 2-3 songs that made my headlights dim. not bad enough to warrant a HO alt, but i do need to get a new battery under the hood, its an older interstate battery, but enough of that... so far i have NOTHING but good things to say about FI!!! thanks to everyone who got this badass sub to me! pics are soon to come
