I have a 01 VW Beetle w/ Monsoon system. Yesterday only my dash speakers are working and the volume needs to be way up to even hear them. Question to you, does that sound like my Monsson amp or stock H.U. is the culprit? Worked great yesterday morning but last night did not. I just ordered a new H.U. and sub from Crutchfield and was planning on using my monsoon with this setup. I don't care if the H.U. failed but don't want the Monsoon amp to fail. Any suggestions on what to look at? Fuses?
