I have the full clarion stereo system in my 99 400 sundancer. It sounds horrible and is in great need of a replacement. Does anyone know if if this system has an amp anywhere, or just some general tips on this system. id like to replace all the speakers, head unit, amp, etc. Id like to avoid a full blown re-wire, custom kit, if I could replace everything in a pug-and-play kind of manner. Any tips would be helpful. Thanks.
