I have a jvc kd-g430 and was wondering if anyone could suggest a good 10 inch sub woofer for under 100$?

Question

well im just starting to learn about car audio so the specs say 20rms x4(mos-fet 50w x 4 max.)

Answer 1

there are a lot of good subs out there but to suggest a sub it would be good to know how many RMS watts you were planing on having

Answer 2

JL Audio makes a 10w1 and Rockford has their P1S4D10. Those are about as good as you're going to get for that price. I'd be inclined to go with the JL Audio if you can find it that cheap locally.
