Custom built fiberglass enclosure which houses a Jl Audio 10w0. It is being driven by the rear channels of the Usacoustics amp
Here's a pic of the amp rack that resides in the trunk of the car. The amplifier is a UsAcoustics 4065 which pushes 65x4. The front channels are running the jl components and the rear channels are bridged and pushing the 10w0.
Here are some pics of the building process.
Original console
Console taped and ready for the fiberglass to be put on. I did this to get the original shape of the console.
I made an exact copy of the where the console used to be at, that way the new box would fit like the original.
