I have had a pioneer hu in my car for almost 2 years now. Now complaints whatsoever. I have no idea what the max volume is bc i have never gone higher than 46 with it lol. Im afraid the subs would blowout my back window! It makes the factory speakers in my blazer sound nice too. I think thats sorta what Rich was saying about volume levels^. Ive heard JVCs are ok too but i wouldnt get the clarion. When i was doing research into mine 2 years ago the guy at the audio shop said he really didnt like them that much. Just my 2cents
