I have never added a subwoofer like this before.. I seen it on crutchfield, because they spam my email daily and I just decided to see if anything new and cool was out.. Anyway, I seen this box https://www.crutchfield.com/p_13694278/JL-Audio-Stealthbox.html and wanted to know a couple things.. 1 does adding a downward facing sub onto two that are already top facing, present any weird problems? 2 my wires would have to be about 3 foot long from sub to sub, would that cause any problems?
