I live close to were Cadence has their main office. So I paid the a visit to check out their home stuff. I used a couple if their car subs about 10 years ago, and they had a sub out like the kicker solo-baric. In fact it was a kicker just made in japan or china. All their stuff is dupped off other manufactered product. They pretty much spec out what they want to copy and send it over seas..The woofers we had were bullet proof. We had Zapco amps(some of the best american made amps for cars) pounding them for hours and they held up.. I useed one of their car amps once and it was a alpine v-12 but with cadence all over it. So what I am trying to say is that if the cadence looks light another name brand sub out there and the spec are real close. It is most likely going to be a less exspensive close sounding clone..Has anyone had their stuff for more than a year?
