Question about Sony Xplod XM-554ZR Car Audio Amplifier
I just bought this thing ive upgraded from a 250 watt amp to the 600 hooked i changed the gage of the wire to 8 (from the battery) and hooked everything up the exact same but now im not getting any power to the amp any suggestions.
A couple of things you can try:
1. check for B+12 on the 1st and 2nd terminals of the Power Connector using a voltmeter;
2. temporarily put a jumper on the 1st & 2nd terminal of the Power Connector;
3. the usual, check for loose connection, fuses, wires, connectors.
if there is +12 on both terminal and amp is still dead, then it is internal;
if there is +12 on terminal 2 but none on 1, then it is the wiring from the head unit or the trigger of the head unit that is the issue;
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
