I think I disassembled my sub full of anticipation yesterday I got my μ-dim prox 2.1 kd… well I didn’t batter for a long time….840.4 out the monoblock in… and first plugged, wired, checked, fitted… turned on, went…. but suddenly there was a funny noise from the sub, the end stage went in protection and was out, it sank… I radio out and on again. first quiet, went again.. snout full and continued today… slowly started again loud g emacht.. puff, no stinking.. end stage not in protection.. I suspect that yesterday I chased through one and today the other spule of my hollywood edge 1524d4… the subwoofer was already running on 2 channels of the 840.4, but apparently he just didn’t get along with the balance of the monoblock or I was too stupid… just too stupid… radio to 60%, gain to 80%, end stage remote full.. well… I have the subwoofer at 2 ohm with 1.3 kw operated abzuglcih of the settings.. so i think that about 1 kw was available to him for which he is also designed..but why did he rip up the ass?? I bought the final stage used, CAN you have something to do with it?, the final stage definitely goes still…. I’m the opinion that the sub simply would have had to tolerate the performance according to information but now it’s true that the spits are going through and nothing is moving more… would you have had some theories what else could have happened? 352 current at ner stiner spv 44… the cable was just totally micky and I thought that it was going through and got me better thicker today.. but as I said the same… can nciht imagine that the cables have messed up… hope you have paat tips.. doesn’t want to make the mistake again!!!
