It was a long project but shit, it sure was fun installing it! I bought the 2 subs off from ebay a few months back, bought two for less than $140 shipped I think...I cant really remember any more. The amp i got hella lucky, I bought it from craigslist for cheap, brand new though! If u buy that amp from Best Buy its around $300ish. So the whole system was roughly around $300ish? (~$140 for subs, ~110 for the amp and ~50 for the amp kit.)
Kyee, I love in Daly City. If you wanna compare, Im down to meet up!
EDIT: subs were ~300 shipped, amp for ~120, amp kit for ~50, Dynamat ~60
