For that price I would do it. I have 2 12s in my car right now and they sound clean. Not the most impressive SPL wise, but they are made to be put in a sealed box for SQ. Alot of people on this site might not agree with me but I think they are good subs for that price.
like he said there not really spl subs.. regardless yes they will still hit hard provided you give them the proper power, of course u can put them in ported boxes and still gain spl ..but they wont sound anywhere near as good
i hit 146.5 dB in a slot ported box with around 1600 watts RMS. even though it is a ported box it is designed for SQ over SPL. so i guess to answer your question it does hit hard but the subs arnt really designed to hit really hard.
