Upgrading to the infinity 6092(6x9) they are 2 ohm and the stockers are 4 ohm will this burn the amp over time?
Perhaps they changed in 2011, but the 2010 speakers/amp were 2Ω on models III-V (3-5) JBLs, with 4Ω only used with the base models I-II (1-2) system. Check you "stock" speaker as it should be listed on the back.
