These were very expensive RCAs from a few years ago. All they have really done is sit in a closet. They were replaced by a reliable set I've been using for 10 years or more made by Lightning Audio which is generally considered a crappy brand. Doesn't say much for Stinger.

 

ive never heard of any1 using a stinger alt, but i do know stinger is an excellent and very well known company, so i could imagine them making bad alts. EA is very well known over at caraudio.com, thats how i learned about them. and yes im sure your right, stingers probably more expensive cause your paying for the name. with my experence of EA alts, im very satisfied. my alt handles every bit of 2500watts with hardly any V dips.
