I bought the Alpine KTP-445 Power Pack to boost the sound coming from my Alpine CDE-9852. When I installed it my stereo made a pulsing sound and I had way less volume coming through my speakers. The max volume with the Power Pack installed was lower than a normal listening volume. I have a 99 FOrd Contour SVT if it matters. My HU is compatible and its plug and play install, anyone know whats up?
