I use mine maybe 2-3 hours a week, that is play cd's. Its 3 years and works like new. Also I would say match speakers up with the deck, that is find a good combo. Some decks sound good w/ some speaker and some speakers sound like crap w/ some decks. I have a pioneer deck it has good mids, I need better speakers b/c I have kenwoods which have better highs (really crappy lows) soso mids.
