Hey guys, I don't really know much about car audio / stereo / whatever equipment.

Basically, I want a LOT of bass (okay, so i'm an 18 year old teenager, what did you expect?) in my car. I figured that since it is a small car, a small sub would be plenty loud enough.

I have a cheap headunit (Pioneer DEH-4800MP). I would really rather not replace this but if I have to, I have to.

Do I need to upgrade the amp? I was thinking of putting about a 10'' sub in the trunk, but i'm not sure if I need a new amp or the 10'' would be big enough / loud enough / etc.

Basically, can anyone recommend me some products? I do not know which brands are good / etc.

I also would like to know exactly how hard it would be to install all this jazz.. I would rather not drill into anything if possible.

Also, one last thing! I do not want to spend a lot of money, not necessarily the cheapest route.. just somewhat cheap!

Thanks if you can help me!
