I drive a 03 altima not sure what setup to go with. I have never heard a Avalanche before but have read good stuff about it! Comparing 2 12w6v2 VS 1 Avalanche which will have higher SLP and SQ?
well I have had both setups that you are reffering to. The w6v2 has great SQ and decent spl but the Avalanche takes the cake in the SPL department by a long shot and is very siilar in SQ. I absolutely love my avalanche sub and would recomend it to anyone.
