Do you have just the stock sound system? Moon&Tunes? Navigation?Generally, we see people upgrading their speakers with two pairs of 6.5" speakers. I generally reccomend Polk's, and the Infinity Reference series sounds really good, as well.But, your budget is really important too. Generally when you upgrade speakers, you'll soon want to upgrade the radio, as well. This will give you the maximum sound upgrade. You don't want to go -too- low in the spending, otherwise you're not really upgrading much. For example, you can go with these Polk db650's from Crutchfield, and get "Buy one, one pair 1/2 off", bringing the cost to $150.

If you search around, some other good speakers are any of the Infinity's, JBL, JL Audio, MTX, and Kicker. There are many other brands out there, and if you want, if you find something that more fits the price you're looking for, let us know. We'll give you an honest opinion!
