My mom just bought a tercel about 2 months ago, now I used to have subs, amp and the works in my old car until I had to scrap it. I was wondering what would be a cheap and space saving setup. I still have my old subs which are the Audiobahn AW121T 2 X 12's and a clarion DPX1000 I think (it's the 1000 watt one, I can't remmebr off the top of my head), but I dno't want to use that in the tercel, so could someone help me.
