Sdr 8s are awesomeness

I bought these skar sdr 8s package not knowing anything about them or skar . I’ve been into bass and nice car audio since i was 16 an I’m now 39. I’ve never dreamed some 8s would sound as good and hit like this package does . I have them in an 08 Ford Escape and they slam . I’m very happy with my purchase. Will be buying more skar in future. I have these on a rp 750x1 an they want more power .

Dual 8

Crazy Bass

Very impressive for a set of lower power 8s

8’s that hit hard as a mutha fucka

Put this in my Subaru. I had a skar 12 that really impressed, but wow these 8’s are the real deal. Amazing bass for such a small package. Everyone is in disbelief (including myself) that it’s only 2 8’s making all that racket lol.

There’s value in Skar

I’m running the 8’s on great electrical with a 1500rms DD audio amp. They never clip but I smell coil when I push them too hard. Still holding strong and nobody ever believes it’s two Skar 8’s
