They sound great.

Wow I bought two of this speakers about a few days ago. Finally arrived last night and installed them this morning.more. Sound quality is amazing and no distortion. Definitely recommended for anyone who wants to replace those worn factory stock speakers.

best deal

as usual, MTX products never fails to impress me, I've always been a true fanatic and this woofer is super loud and even under it RMS power rating it's still loud and great quality sound. i'll recommend this over any other woofers as I used other brands such as 18 sound, ciare, PRV audio, selenium even faital pro.

replacement speakers

I have a 1990 jeep wrangler and one speaker on my center pod blew. When I bought and received the first speaker I found it wouldn't fit without modifications. So naturally I ordered this set of speakers and hooked it up to my small Rockford fosgate amp. I was impressed with the bass I got out of the speakers and their ability to hang with the fos. I recommend these and would buy them over again.
