I swapped them with the SL speakers, much better sound.
maybe they were already replaced, who knows, but when I pulled the SL speakers from the SL Versa at the junkyard, they were Clarion branded. Car is (was) a 2008 SL.Just to add- too lazy to edit!
Versa SL speakers are made by Blaupunkt
2004-2006 Altima speakers are made by Clarion
