Question about Sony XM-2150GSX Car Audio Amplifier
I have an 8" sub woofer hooked up to a small amp. The amp powers on but the sub will not make any sound. The terminals for the sub wires that go into the amp and to the sub have not changed and are in the right location. The remote wire (spliced into the remote wire from the head unit)has also not been changed and and sub woofer feature on my head unit is on. The funny thing is that it used to work just fine. But ever since I changed the battery terminal to a gold plated one with an axillary hook up for the amp power wire, the sub has not worked. Everything is tightly connected. What could be the problem?
I would double-check your RCA's on the amplifier. You should hear a thud if you unplug them. If not they are either not hooked up or defective.
