This component set has amazing quality, polk audio has outdone themselves. I had this set on my stock radio in my GMC truck but didn't care for the sq so i purchased the pioneer premier DEH-610BT and the quality improved but i still thought it could be better, so I put this set on an amplifier, and WOW I had finally realized why I purchased this component set. I had never heard such a great sound from such small drivers. I was only pushing 150 watts per channel but i'm working on getting a new amplifier (Polk audio Pa1100.5) that should drive them to their max 250 watts, and see about the output then. Absolutely the greatest car mid range and hi range system I have ever heard.
