I really like the 4080 custom box but cant afford the price tag. Found this on ebay it looks kinda cheap but the guy got some good reviews. I would be installing two 10 inch T1's

Also would a single T1 sound better than 2?

I wanna have 4080 too, but (in my op) it is way too pricey.
I saw the seller in in this forums somewhere.

"Search" and try to contact him.

Very cool. Have not seen that before. Seems like an outstanding deal. If you're ok with using your entire trunk, then I'd jump on it.
