VISONIK 12D
I have been working with car audio for years and have a stereo in most of my cars... These subs aren't no MTX thunder 9500 or a JL Audio W7, but with the right box and amp, these subs sound amazing. Currently i have a dual 10" wavebox built powered by a JL 300/2 and these things sound AMAZING!!!!!!!!!! they are a good starter sub.. dont let people tell you otherwise, its the box that counts!

This sub i wouldnt recommend to anyone that is thinking of upgrading there systems. I bought this sub in a store in my town for $60 canadian(no warranty either). There are better subs that are around for about the same price with better sound quality and a harder hit. For a 12" sub i was dissapointed no good with the lows. But if you like the sub good luck trying to find it any cheaper than here/and an authorized dealer.
