Got back from my business trip yesterday and was able to install my box and sub this afternoon. The single 12" box works great and now I have plenty of "bump" with the Treo TSI sub powered by an Alpine M450 amp running off the stock HU.


I already did that, the Treo has decent excursion so I moved it forward to be safe. I'm still messing with the amp setting but for a sub $100 sub this thing can dig pretty deep.Fox Delta said:that looks good - I have the same box from Tech - it looks like you should slide yours toward the front of the truck about 3 more inches. I had mine in about the same spot as you and when I raised the seat I saw marks where the Sub was contacting the bottom of the seat. I keep mine bumping hard when I'm alone though (90% of the time). you can probably keep it there if you don't turn it up too much though....
