Unreal how good of sound quality these subs are. I have them in my 08 Hyundai suv there fantastic if I was able to put two more in I would. Best starter pack for getting into audio system this is a great deal honestly is. I’ll recommend Skar audio to anyone that asks about car audio. Crisp clean drops box is clean as can be

Beast of a combo

This setup with 1500 rms running to them in an extended cab diesel is superb. Soul shaking bass and great sound quality. Orginally I had some clipping from one of the subs and I immediately called and asked what could be done. One of the great people of skar audio walked me through what to do and I simply had my amp tuned incorrectly. After fixing the tuning, what a difference. Amazing

Omg when I received the word they arrived at my job couldn't wait to get back in town to hook them up.. Damn I'm glad I waited to get these bad boys.. The sound is amazing the bass is fucking awesome. came pack right so there was no damages I will be finishing my system off with your products.. Can I have a Skar sticker so I can put on my back window?
