So after installing my first system in my ES300 I was very disappointed in the output due to the soundproofed trunk with the metal plate and thick rear seats and what not.

I got a mission to find a way to get my car louder and removed some excess stuff behind the rear seat to give my car a full opening from the armrest into the trunk.

From there I found the best box builder I could and had him design me a plan and we decided on this.

A 4th Order Bandpass box that has an external port firing through the armrest. This box will hold 2 10's and because it is a 4th order it should have excellent SQ and with the port through the armrest should allow for maximum SPL. For those who don't know, a 4th order bandpass is kinda of like sealed subwoofer inside the box in which ALL the bass comes from the port.

Wish me luck and I'll let you guys know how it goes in the next week or so.

 

Yeah, definitely keep us posted, oh and share some pics when you get the chance
