So just installed the 400 watt system yesterday. About 4 hours with plug and play. Biggest pain is installing the amp for door speakers. All I can say is I hope you never have to get to that panel again. Makes it a lot tougher to access. Beside the sub woofer base having lots of reverberation , really not noticing any diff in volume. Thinking about upgrading door speakers, but not sure besides spending money this will give me more volume? These parts are another 180.00. through amazon.
Has anyone done this and did it give you better sound and more volume?
