im planning on putting a system into my 2000 celica whenever i can get the money put together for it. i have a friend that is like the head car audio guy up at circuit city and he was helping me put it all together. i want to have a CD/MP3 player with some good bass and good sound quality. he suggested for the head unit that i get the Alpine 9807. i looked at it and it seems to be a good deal. its got everything i was looking for and its not too expensive. for the sub he said i should get a 12" Alpine Type R. as for the amp we didnt really have time to look around at em, but i want about 600-800 watts. does this sound like a decent system? any help is appreciated.
