i was at a shop earlier today and i saw that they had the alpine type s and r on sale. the type s were on sale for 99 a piece. and i dont remember how much the type Rs were. right now i currently have to 12" kicker comps (theyre kinda old) with a 600w hifonics amp. do you guys think i should buy the ype s or rs, or could my amp even handle it or what?
