not sure if a bunch of ppl know but you cant get stinger hpm lvl3 rca for $21ish from a seller on eBay.... these sell close to a $100 from other stores on eBay.
i got the 6 channel ones, the wire is kinda stiff.. stiffer than 4ga kicker hyperflex wire and almost the same size!! LOL
tho i found it easy'r to install these that normal rca.
there connected to a kicker 4channel with some oz comps and diamond 6x9's...
very very well worth the money!!!!!!!!!!
