here are some pics of my first set of subs and amp ever i got em for 75 dollars total amp subs in box power and ground wire everything. hooked em up with ease have the amp on a on/off switch i installed located on my inside fuse box cover that i forgot to picture. i like them so far sound good for the price, and i put my LOC in my ashtray and cut some holes for the lines to go out the back so i can slide it open and turn down the amp if i want to. does the brown wire pictured need to be hooked up to anything? its on the side the aux wires come out of the loc. and it all runs fine w/o it hooked up. what do you all think. im thinking of painting the silver part of the amp black also.
