I wouldn't suggest this unit to anyone. I just bought this unit on 6-18-2010 and by reading the reviews everyone left i felt pretty good about the unit. After installing the unit i was having alt noise and background noise coming from the unit and after buying ground loops and re grounding the unit several times nothing changed. So i went to and audio shop and they check it out and said it was the unit and not my ground at all and that's why the ground loops didn't work...so i took it other places and all said the same that power acoustik are not good units for sound/ the next problem was when I'm out of the car and the inside of the car gets hot the unit will not play any cds or dvds or any sound period...i hate this unit I'm looking at the JVC's now i wouldn't recommended anyone to buy this unit....and when playing cds and dvds the sound will not get loud at all! if you like to adjust equalizers for the best sound this unit is not the one it only has treble and bass
