actually that is the first thing i changed was the sound system. i got 4 type S speakers and a new head unit. sounds much better than the stock.

how hard is it to install the short ram? also, are there any good performance chips for the tribute i?

 

a short ram is very easy to install vs. a cai, good luck finding a performence chip for ANY 06 mazda, when you do, hell let me know, oh and what brand speakers and head unit did you go with.
