there are people on here would wuold beg to differ....
Jensen is the more reputable name, and ifor a first system, in a budget situation, i wouldn't think for more than a few seconds about putting it together with some of their higher end products...
I read on here someone who runs a shop and set upa system for someone with jensen subs, (or maybe it was for their friend? i cant remeber) and it sounded great...
as many on here say, It's ALL about the install!
so in short, get teh jensen, and put them in decent boxes with clean power, not too much, but not too little either, i would go right around waht the manufactuirer suggests... if not even a little bit lower (50 watts) may help tehm with some of the reliability issues...
basically, anything can sound good, and anything can sound crappy... its all in the installation...
