Luke99 told me to look you up and ask you questions about building a ported wall in my car. I am building a ported box/wall for 6 HFX12D4 12” subwoofers. The box measurements are 40” length x 18” width” x 34” height. There will be two 5” ports which are 3.6” long. The tuning frequency is for 32 Hertz. The box enclosure volume is 14.167 cubic feet. I was wondering, would these measurements be efficient enough for the subwoofers? If not, do the ports need to be shorter/longer? Or, should the box measurements be smaller? Box enclosure volume? I do not want the box to be too big/small. The subwoofers will be powered by two Planet Audio AC4000.1D Amplifiers strapped together. The wall will be going in a 1995 2 door Toyota Tercel (back seat removed). The measurements (listed above) are the maximum measurements the Tercel can fit due to limited space. I used the port length calculator to obtain the measurements of the port size.

Hi Steve!
I was talking to Luke Paddle recently and he mentioned that your show in Kamloops this summer will/may have an SQ component. Is it USACi or IASCA sanctioned? Point value 1x vs 2x?
Have a few SQ competitors here in Vancouver area thinking about making the short drive up to your show!
