For subs i guess My link, if you want a quality amp My link or a My link, budgetbrand could be My link or there is another one from the same brand My link. But please ask the forum
i can not see the diffrence between those both only size and price, could realy be that the 20 $ more is a must have. Here the cheapest ampinstelationkit My link with the right size from Audiosavings. So you have a rest from around 150-200$ for wood for the box and some speakers.
For boxdesign plz ask in the subwoofer section, there is a boxcalculator as well. The Kicker subs are known that they can get very good in the right box.
For speaker i guess you a pair of crecsendos but i dont know if them aviable, shoot a mail to "Twistidchild420".
