Okay...I got couple questions.. planning on improving my sound system in the car just a tad bit but not heart pounding or anything like that. Any suggestions? maybe just some one sub or something.. also does anyone know if the stock corolla 6 CD changer stereo has RCA outputs in the back to hook up an amp? Lastly, I want to get a mesh grill (altis) probably off of Ebay. Is it worth painting the same color as the car (white) or should it just be left black? does this grill fit good? if anyone can help me out with some answers that would be awesome.. thanks everyone in advance. appreciate it.
