The amp is shit and the subs are crap! If you plan to have bump in your ride for longer than 2 days, plan to spend a lil more money on equipment b/c those links you have posted, that stuff just truely sucks. I know its my personal opinion, just before you buy, do some research. I run $600 buck subs and $1100 dollar amps that have more power than you can imagine. My single 8in sub I bet will give more bass than what you plan to buy. PM me if you are looking to get a good sounding system.
