i have a del sol so there isnt much space im going to be putting the sub in the boot(it'll be to messy putting it behind the seats). Space gets limited in the boot when the roof comes off.

Right now with my current set up i have no bass at all its really really ugly. After i get the sub ill be connecting the rear spears to the deck and the sub to the amp.

All i want is some bass not to fussy about brand names or anything, but i still dont wont garbage.

The sub i think will have to be facing up wards because i dont think itll fit standing up. It has to be a 12inch sub i reckon 10s are to punchy
how does ur car look like? if i were u, i would seal the front doors (assume ur woofers r installed on the doors) and c how much bass ur speakers r capable of. 10" move faster and produces more accurate bass. it's good for techno. 12" is louder due to more cone area but it will require more power too. sub facing up, forward or backward does make a difference. maybe build a temp box (or borrow it from someone) and c which way is the best u like.
