I bought a new 2013 Wrangler Unlimited Sport with the stock/base model sound system this weekend. Today I had a new Pioneer AppRadio 3 and 4 Alpine 6.5 speakers installed.... and it sounds terrible. There is no depth or "warmth" to the sound, no vibrations so to speak, the music sounds like it's coming from an elevator speaker. It could be the EQ but I messed with that for 45 minutes and am still not getting even the sound I had with the stock system. Any ideas?
