craftsman Posted January 15, 2006 Share Posted January 15, 2006 Hi John, With my 4.1s, I never really had any problems with them before openning them up. I purchased the set off of Ebay and being the tinker in me, I openned them up to see what's up. At that point, I noticed the issues with R12 and R26 so I replaced them. The set worked for months until something else caused the 4.1s to be dead - I've haven't found out what the something else is, yet. Since it's fine when you initally power it up and then starts having issues after it gets warm, I would assume it is a heat related issue. Since the discolouration comes from heat, it is a good chance that changing the resistors will address your problem. Really, the only cost involved is a little time and a couple of bucks...

jgr82 Posted January 19, 2006 Share Posted January 19, 2006 Hi, Today I replaced my R-12 & R-26 resistors. I thought I had it fixed, no rumbling. But then after being on for aprox 2 hours they started to rumble again. I am so bumming. Do you have any other ideas of what could cause the sub to make these rumbling noises. Thanks Much.

craftsman Posted March 11, 2006 Share Posted March 11, 2006 Hi Willdo, Almost any electronics parts store will be able to get you the resistors. Failing that you can try mailorder but the cost of shipping may be a bit high for two resistors.... Quote Link to comment Share on other sites More sharing options...
