hope i dont get flamed, but i wanna put some kick in my car. Now i dont want no super duper 10,000 watt system, i have a decent head unit already, and now im looking for a sub/s and amp. Now i know a lot of people have 2 12 inch subs, but i want a usable trunk too. I also want some decent base and sound. now where the seats pull down in our cars, behind that theres a space in there and i was wondering if its possible to get a sub and box in there and have it put out good sound and base tone. if not im willing to go with 2 subs or what ever would need to be done. If i do this my self (my friend will help me with all the wiring) how would you get the subs and box to stay put while you cruise around town? also what type of sub/s amp should i get and wont cost me a fortune. looking for 100 - 400 bucks max.
