DEMOS TO SERIOUS BUYERS ONLY.

Sub was never pushed very hard since amp(gain and bass boost) was never maxed out. Maybe 50-55% power. Didnt need it to push too hard since I had a hatch and it was loud by default
I PREFER NOT TO PART AT THIS TIME
Priced at $350 FIRM
Box cost about $200ish to make alone, I bought the box from a professional car audio installer.

I still have the original box for the amp too.
