For less than $120 what should I do about subs?

I have a 92 Notch. I have 2 8" JL Audios in my truck. The only way I could fit a box in was to slide it in on the passenger side with the speakers facing across the trunk toward the drivers side....I have a full-size spare due to having a police package. Otherwise, the box would have fit normally where the spare tire is. The full-size spare sticks up about 1.5-2" above the trunk floor, so the box was too high if I put it on top of the spare. Otherwise, I don't think you'll get any 10"s in there unless u have a custom box built, or if you get truck boxes. That's just the experience I had. I went to some audio places and they said they could build a custom box but it would take up most of the trunk.

$80 Refurbished Profile amp? 200Wx2 at 4ohms, 300Wx2 at 2ohms - not bad.
