Hey i just got an offer to buy two 12 inch JL Audio W6 subwoofers from a guy my friend knows in a sealed box for 100 bux. Is this a good deal? I havent actually seen or heard the subs yet so im not sure if there is ne thing rong wit them. But i had previously bin planning on buying 2 12 inch MTX Thunder8000s but i then realized that im dangerously low on funds. My current setup has my brothers old 12 inch pioneers in a sealed box. Do u think i shud upgrade to the JL Audios or just wait and get the MTX?
