First and foremost I would like to introduce myself. I'm james from hondo texas. Small town west of San Antonio.ive been playing with audio for about 17 years and for being self taught in a town who's only audio retailer is wal mart, I think I do ok. I recently acquired a pair of aa avalanche and a sundown saz1500d which go in the wife's expedition an my set up is a pair of old sundown sd10s on a Polk pa880. Mids and highs r given to mb quart components of a kenwood cheapo hu and the expedition is pretty much the same exept for the hu which is the kenwood ddx514. I build and design my own enclosures mostly ported and they sound clean inho. I appreciate any and all opinions and knowledge that u can give me thank.
