MiniTruck Bumpin’

The Sony Stereo that came with the car is a decent head unit for what intend to use it for. The 4 mid-sized speakers are not stock, they have been replaced at some point in the trucks life.

What is lacking is the bass tone. I decided to go with the largest tuned box I could fit behind the seat. This itself is a challenge due to the reinforcement metal that was used to brace the cab rear section. A “triangle” metal brace and plate was fabricated in the center to add structure strength and eliminate sheet metal flex. There is also a 1/2″ tubes used to frame the upper part of the cab box.

I selected two 12″ Pioneer shallow box subwoofers. These allowed me to use all of the seat adjustable leg room range. The sub box is tuned for these particular model subwoofers so optimum bass response is achieved.

I don’t know if it is because the open top environment but this setup is one of the hardest and clean hitting bass response rides I’ve ever built. Having all the Dynamat installed helps too, you don’t hear any cheap ass vibrations that a ghetto ride will make.

I added an inline fuse to protect the amplifier. The +12VDC source this fuse is protecting will also be used to provide voltage to HydroDrop V2 Base Station (Wireless Air Ride Controller).

An variable base controller knob will be added for volume control. This will take the place of using a flat blade screw driver to set the gain of the subwoofer signal.
