I'm working with a 2001 jeep cherokee sport all stock, 800 crank battery, 110 crank alternator (I wanna get a 220 crank alt from powerbastards soon after) , and I want to get aftermarket speakers (Polk Audio db651s 6-1/2" 165W 2-Way db Series Slim Mount Coaxial Car Speakers for the front and Polk Audio db521 5-1/4" 135W 2-Way db Series Coaxial Car Speakers for the rear roof). I know I need an amp to power those just found out about the mini amps that hide behind the HU so I'm going to look into some of those but any recommendations are appreciated as I really have no technical idea what I'm doing so thanks for all the replies!
Edit: Forgot, I dont care how much space it takes up as long as its behind my back seats. The box is going to be built by my buddy found out its a lot cheaper that way lol
