So here it goes, most of my equipment are older hand me downs from my dad but I dare say it still sounds better than any of my buddies rides, I'll get to the goods now 97 jeep cherokee pioneer deh-280mp Head UnitI I have installed a 200 amp alt and upgraded to 2# wiring. 6.5 infinity kappas (I think) in the rear sound bar 4.5 A/D/S speakers in the front doors (can't find any info on these, apparently they were top of the line when my dad bought them) rockford fosgate 4.6x 300W amp to power all 4 speakers (made in the usa) two 10" 1050W reference series subs Infinity 611a reference Amp Currently I'm looking for a single larger sub that will match up nicely with my amp and will give me similar or better performance than the two 10's so I can preserve space, might go for more bass way down the road when I get a roof rack but that wont be for a while. I was looking at a Sundown Sa-12 as I've heard good things about them. 200$ is around what I'm willing to spend for a new sub (little wiggle room on the budget but not a lot). So I guess thats that lol
