opinions sr20 haibane

Okay I need some help badly. I have a b12 on order. I have a tempest and shiva sitting in my room. I have another tempest comming. I have a hifonics brutus bx1500d. For now I'm goin to run two tempests and possibly wait for the b 12. Well that was the plan but I'm thinking not now. I'm thinking run the two tempests cancell the b12 and go with 2 xxx 15's. I would do brahma 15's but they cost more and re is a little bit mroe spl geared. I would still consider b15's and possibly ill upgrade the 12 to a 15 and then save for a second one and second brutus. I've even considered an xxx18. I NEED OPINIONS I like low loud bass with good sq. I don't know what i want to do and i need feedback. I have 5.5 cubes to work with after aproximate displacements. The port will be 4"x30" going into the cabin and the subs will be firing up in the trunk of a mustang.

I suggest the b12 honestly... or a XXX12, you don't need 2 subs with that kind of power. Although a b12 might not take the power well the XXX will love it sealed

I wanna hit close to 150. I'm a basshead so one b12 won't do it for me were talkin 142-143 tops with it.

run a XXX15 and port it, it is possible to hit 150

how much louder is a xxx15 then a b15

install... all install

Agreed but i just had a big hit in the pocket so the b12 will have to do for now...after i run it ill just get another once i get cash again.
