the sub i have now is the BIC america V-1220 which just under 200 bucks when i bought it,is perfect for my budget,im going to add the sony 10"SAW2500, i cant afford to spend alot on equipment,i simply dont make much money to afford the highend stuff like everyone else has,but i like the way they sound(both subs)...
and that sony sub was the first one i had and it is really not that bad either,sure its only a 100 watts but the woofer is super tough kevlar material so i think its fairly good ....so thats my plan...
