I just finished building a custom system for my IS. i built a custom box and a custom beauty board so that i can still get to the spare if i need it and still be able to fit my S15L7 with the right air space(15"" kicker/ kenwood amp 850RMS tuned to the lowest setting).

 

Very nice...clean install

 

Nice, that looks pretty cool. Where did you house the amp and everything? Just behind the wall? And why havent you blacked out or at least tinted those bumper reflectors????!!!! Especially with your tail lights being tinted!

 

Missing the trunk space at all?

 

wow 15L7!!!!!!!!!!!!!!!! I have a 10w7 and i can't even handle the bass lol. Very very nice install, clean setup

 

I think you need a larger speaker...seriously - nice install, very clean - how does it sound?

 

cool your setup box looks like mine, I love clean and stealth, that 15" must slappppp

 

I have the amp behind the seat and infront of the box. The system sounds good i turned the amp down all the way because i dont want to rattle every thing loose, we have a problem with that anyway and i dont need to make it worse. So im pushing a 2000 RMS speaker at 1/6 of its potential and is louder then my friends BMW with 2 kicker comps/ 500JL amp .

 

that looks awesome! great job.
