Through my work i can pick up rockford fosgate HE2 12's for ~100 a piece and a sealed box for $30 (gotta love employee discount). My question is how nice are these subs and how will they sound in my car. I would like relatively clean bass but at the same time be able to make the car shake if i want to. What do you guys think of the HE2's? Keeping in mind im not really that much of an audiophile i just wanna upgrade from the two crappy JBL 10's i have right now. I have a Acura Integra Hatchback and a JVC deck(w/ 4v preout), infinity doorspeakers(boston acoustic soon hopefully), and a 600w amp. What should i do? Currently i have a trapezoid bandpass box so in theory i could go with the he2 10's as well. thanks in advance. Think i should pick up a cap while im at it?
