Ok Ive been around car audio for about 6 years now, and competed for 2 in SPL only, but my main focus is SQ (sound quality). I read that someone mentioned running the ground wire from battery to the trunk. (I have god tips on wiring also)I highly advise you to stay away from that method! Try to make your ground run from your amp to the car chassis the shortest length as possible! Next for wiring sizes 8 agw is no good for some amps by themselves. Check with the amp reccomendations first. My Orion XTR1400 will melt 8 awg on that long of a run! Your main goal is to compliment the mid/highs in your car so its not as boring to listen to (my opinion) I can make any sub sound decent with the right install. And whoever wrote that "speaker A" sounded like crap playing midrange, why were you trying to play a midrange freq through a sub that should play bass in a reccomended 20 through 120-180hz anyways? Mine wont sound good playing a 1000hz note either. My best advice to you is to listen to what is available to you, maybe the shop has a install with those subs or someone you know has a friend with them. And BTW solos sound nice, but you need to feed them alot and the right amount of power!And I never knew the xpl were solos, but maybe Im wrong. 10"s or 12"s can sound just the same, but the 12"s can usually play lower hz than the 10"s. But now my first questions to ask you is your musical taste that was answered and what amp is going to run the sub/subs. And well if we really want to get technical we could throw in efficienty of the subs you choose to get the most spl per watt too :p

BTW its a B!tch to run 4 awg in the tours, and never run the rca's on same side of car as power.
Oh and this is by no means a flame to anyones post.

and what is a EBS enclosure?? maybe I call it something diff than you i dunno....


bleh......
