One of the best $135 dollars I ever spent! No, I will start off with saying in the beginning, I was very very VERY skeptical about Skar Audio. I heard alot of good/bad stuff about them. I almost bought one of their ZVXv2 subs but it didn’t come in a 10 inch, instead I found a brand new Orion hcca 10 on sale with warranty. Goldmime of a sub!I was watching countless videos on YouTube about the brand, with sub, amps, door speakers etc. I finally bit the bullet and bought this one. At first, the main issue I was experiencing…
