Subwoofer enclosure - Toyota Mark II, 2.0 liter, 1995

I expelled the sub from the rear shelf and began to design the case. I calculated the required volume and measured everything and proceeded to assemble. The old kitchen set made of chipboard fell victim to sabobuilding (well, don’t use plywood for testing). The body was made as close as possible to the tank, the width to the racks of the trunk + 5 cm to the margin. the depth turned out to be on par with the center of the edge of the rear window (i.e., the center of the body was a little buried in the trunk, and the edges protruded) the height from the compartment dividers (where the stowage is) to the top edge + 2 cm of stock. body put through the spacer shumoizolona to the tank. The tank itself was also smeared with bituminous mastic and paved with Shumkov. Housing type with a phase inverter, but since I did not find a cup for cutting a hole, I put it like that. Swearing at the fact that he did not leave a margin in the power wires, he screwed the amplifier onto the subwoofer case. Turned on ... The bass has become much tougher (it will be corrected when there is a phase inverter), the speaker feels better. there is no previous rattle of the rear shelf and the metal that is located there. Lights, bumper, license plate and trunk lid shake. I don’t know what to do, and so everything is under the noise but continues to vibrate. when measuring the sound pressure at all frequencies, the entire system (2 VCL, front component, rear coxial and sub) gave out a pressure of 146 dB ... I continue to bring the sound to what can be called good. I'll take care of the appearance of the luggage compartment when I achieve sound quality) when measuring the sound pressure at all frequencies, the entire system (2 VCL, front component, rear coxial and sub) gave out a pressure of 146 dB ...
