So I am putting together my system and the last part of it is the subs. I have always been a JL guy and loved the 10W6 line. Now with my truck I am running into an issue with space. My first thought was to run three JL 10TW3's behind the back seat which is doable because they are the thin line subs, but now I am also looking at maybe going with one Orion XTR PRO 12. I guess my question is this. Which of these do you think would hit the hardest? I know an HCCA 12" would outdo both of them but don't have that kind of room for the enclosure and not enough power. I already have a Orion XTR 1500.1dz amp so the XTR PRO 12" is perfectly matched and JL told me it's also perfect for the three 10TW3's. I have been told that one XTR PRO 12" will hit harder than the 3 JL10TW's but that was on an Orion forum so obviously some bias there. I would like everyone's honest opinion. Thank you all in advance for any help.
