DIY Downfiring Underseat Aero-Ported Subwoofer Box for Toyota HiAce GL Grandia

Here's another downfiring subwoofer enclosure designed and built specifically for a 2018 Toyota HiAce GL Grandia all purpose van. The usual box-mounted amplifier to drive a slim shallow-mount 12 inch subwoofer, that is powerful enough to shake the whole van without compromising the available space underseat. The enclosure will be then installed under the passenger seat located at second row. There will be some minor modification to be done by sawing off the middle steel seat stand to accommodate the box.
Main component used is the Kenwood KFC-WPS1200F / Excelon KFC-XW1200F shallow-mount 12" subwoofer with single 4 Ohm voice coil. And man, let me tell you! This sub is one hell of the highest quality subwoofer speaker I have ever used! It has very thick and rugged aluminum speaker basket, heavy ferrite magnet, and most of all it has a carbon glass fiber honeycomb cone. Also has a high quality soft rubber surround to add the nice features. High quality push type spring loaded speaker wire terminals are in the house! I HIGHLY RECOMMEND THIS ONE!
Second component is the Nakamichi NKTD1000.1 monoblock 1000w amplifier. Factory specs to outpout about 1000 watt @ 1 Ohm and about 400w RMS on the 4 Ohm impedance. Which is just enough to bump the slim Kenwood Excelon subwoofer which is rated about 350w RMS by the manufacturer.

[@arturomarquez7596]

good but head amp = ☠ to rip, temperature will kill it

[@chrclmnky]

Thanks for the comment. Class D amps are high efficient and do rarely heats. Also the amp is rated to drive a sub as low as 1 Ohm and this Kenwood subwoofer is only 4 Ohm. So everything is ice cold.

I swear everytime i watch one of your video's I don't leave disappointed. I've watched this video long before, but i had to comeback, it's that great lol. Anyways, could this possibly sound good on a medium sized room? Planning to build a underseat subwoofer just like this one, to put it under my desk for my gaming room, as there's not much space on the room and there's quite a few inches to spare underneath my desk.

[@chrclmnky]

@@anxiety1209 what I've noticed when subs are placed in room corners or under the seats of cars/vans is they sound deeper and smoother.

mounting amplifier on a sub box is the biggest mistake

Because it heats up that is why you need to give it sufficient flow.
