Just about to start my first box build.
Just picked up a Pioneer TSW306-C 4 ohm.
I know, nothing special about the sub, but it was $40 with a box and MTX 120x4 with a blown channel.
The box is going to be a bit big for this sub, but I plan on upgrading the sub well before I make another box for the same car.
It's going in the back of a jeep wrangler, which is why I want to go sealed. Not enough room to utilize a ported box. Also, I do prefer tighter bass.
I am going to be picking up a Memphis 400x1 or 300x1 amp. There's usually a few to be had on ebay.
If anyone has any tips, or questions, let me know!
