DIY subwoofer box for dual Pioneer TS-W310D4

A very simple and very easy enclosure build and designed for a couple of brand new Pioneer TS-W310D4 Champion Series car subwoofers.

Each has dual 4 Ohm voice coils which is perfect for dual subwoofer configuration in targeting a final impedance of 1 Ohm. Most mono block amplifiers nowadays are designed to output their maximum at 1 Ohm @ 12.6-14.3 volts.

I think that is all for today and I am very sorry for not including a bass test demo on this one because customer is still out of town but once installed on his car I will hopefully record a video on the big bass test! I hope you like our very simple build today and please let me know what you think! Thank you and see you all soon.
