What would you like to know? amazing construction, made in tennesee. Just the design that is behind these is incredible. Its nice to still see a company that really puts everything they have into their product and really respect their craft. Jeep tjs are a bit weird up front with 4x6. But I have the 6 1/2 in the soundbar. I ran them for a couple months off of an inexpensive jvc head unit, that came with the jeep. They are sensative enough that they sound great powered off the heaf unit. I now got around to running off of an old school rockford 4 channel and they are absolute beasts.
