Nice unit for the price. Only real issue is the volume as another review pointed out. Hadn't planned on using an amp for door speakers but had to run this almost full volume to get loud. Some recordings the speakers still have room to go but the volume on this unit was maxed out. Installed an amp with much more power and not a ton of improvement. Still need to get this thing into the mid to high 20's for decent volume and it will max out shortly after. For a 4 volt unit I shouldn't have to turn the gains up on my amp but may have to to.
