nbshazeezee Posted January 5, 2012 Report Share Posted January 5, 2012 what are you going for. i would probably get a SP4 because it would bang so hard Ye dig, getting loud off little (2) AQ HDC3 12 AQ 2200D - Replaced it, Works great AQ4x90 JBL 662s 2 ways (2)XS 5100r under the hood & A 170amp alt Link to comment Share on other sites More sharing options...
C-Fizzy Posted January 5, 2012 Report Share Posted January 5, 2012 No vs threads allowed. But the sp4 and BL is not even a comparison. That's a joke. under construction I hate People with crappy primered cars rolling on hubcaps that are louder then me. u hate c-fizzy? Link to comment Share on other sites More sharing options...

JacobHazel Posted January 5, 2012 Author Report Share Posted January 5, 2012 get the sp4 i have the bl and its alright but like others stated the bl is not on the same level as the sp4 you should pick either sp4 or btl yeahh i know.. i was gonna start out on the BL as my first 18.. but i kinda already ordered the SP4 but i just wanted to know how much better it is if im gonna drop more cash for it lol.. like i could stop it but it is a pretty good sub? and didnt know you couldnt do a VS post but i just wanna find out so i know i am doing the right thing.. and as far as the SP4 it says it can be sealed.. lol do you think it would even sound good like a 18 sealed..
