I like Kenwood and Pioneer brands myself.. But sometimes a good amp can make the difference between making a decant sub sound real good or bad,
I just picked up a Pioneer Sub and replaced my old sub noname brand, The sound difference was amazing, If i went for a great amp over over a powerful shitty one i would make the car lift rather then rumble bits.
But check the brands and fine print, Many times you will find that ones with all the bells and whistles are not up to scratch..
Even walk into a place that sells systems and get them to test some amps and subs till you find what your after then go to ebay and get them half price.
"Just a matter of time i suppose"
"The elevator is broke, So why don't you test it out"
"I'm not trapped in here with all of you, Your all trapped in here with me"
