Okay.... I have like $200-$250 to spend on some subs/a sub to be powered by a rockford fosgate 300 watt 2 channel amp. I'm kinda leaning twards 10" because i don't want to take up much room in my trunk. I've also never built a box before, so if possible i'd like them in a box. Any suggestions?
a single jl12w6v2 would work well. you might be able to find one on ebay for around that price.
you can pick up a 1 cuft sealed box for around $25. i have a 12w6v2 powered off of a 300wrms in a 1 cuft sealed box right now and it sounds awesome and loud.
