They should have all the wiring and a LOC available.
Whatever shop you go to

Tell them to build a baffle behind the rear seat for 2 15's. Make sure the baffle is built to cover every ridge and groove.

If you look at this baffle, you'll see it fits behind the seat like it's a puzzle piece




The goal here is to isolate the front wave from the rear wave when the subs are doing their thing.

Show them the photos I listed above as a reference if you need to. If you know someone that can build boxes or works with wood, having them build the baffle should save you some coin vs have a shop do it.

Before you get this installed, seal up all holes on the rear deck and under in the trunk area



This stuff works very well & it's cheap

Get 2 rolls

Also, have them wire the car up for 2 amps.
That way, whenever you do upgrade, They don't have to tear the car back up again.
Your next upgrade should be a good double din. Expect to fork away at least 1500 for one and the JDM kit.
Wrathernaut is King in that area

 

Thanks for the pictures, I'll show them tomorrow hopefully they know about it and can do it well. Can't wait to drive by my school
