Im an audio noob and looking for a smaller sub to relieve some space...

im looking for a 8" sub that can handle my jl audio 500/1 amp
will entertain 10" suggestions but rather a 8"

sound quality > loudness
im currently looking at digital designs 1508
and just researched around and looking at the arc audio 8 (but i think my amps too powerful?)

looking to spend around 200.. i believe the dd was 180 last time i checked?

any other suggestions/input?
