[QUOTE="Abquid, post: 8677204, member: 677233"] I took my car back to the installer, a popular chain here in CA. I showed him even when he turned up the subwoofer there was little sound change. His first solution was to EQ all of the lowest frequencies up and leave it at that. But it seemed to me this was just compensating and would be unbalancing the overall sound. I said this wasn't acceptable, so he took out the old amp that powered the sub. The gain on it was turned up all the way. Apparently this amp was underpowered, and this is why putting the noise filter in was lowering the sub. His next, and final method was to put a new, more powerful amp in to drive the sub. I did this, (for an additional $100) and the problem of ground hum AND subwoofer attenuation was gone. So, in a way, the problem is solved but I am very bummed out at the expensive solution. It seems to me if they had put in an adequate amp to begin with I wouldn't have had these ground hum and missing subwoofer issues. All told, I wouldn't go back there, but at least I finally have a working sub. [/QUOTE]
