LOL ahahha ur not gonna get a sub that can hit hard and an amp thats under 350. A good sub thats 12" would cost you at LEAST 300. and thats being generous. And a amp that can push those two sub would be at LEAST 600
2 12" bad subs - at least $600 - $700
2 12" good subs - $1000 and up
1 bad amp - $500
1 good amp - $800 and up
LOL AHHAHAHAHAH if your only willing to send that little on a two subs and amp then you might as well buy nothing because all your gonna get is walmart brands
