I have a JL Audio 12" sub with a SSL 1500 watt single channel amp, my head unit is a Boss bv8685. My amp will power up but the sub only hits once then the amp goes into protection mode, can anyone help me diagnose this issue?
What is the rated wattage for the sub? Also check the wiring from the amp to the sub. Make sure there are no frayed ends of the wire touching the wrong pole.
Any suggestions are appreciated, a friend told me to reposition the ground and I'll try that when it quits rainingLooks all the ssl 1500w amplifiers I seen are class AB and at those prices more than likely highly inefficient...so what could potentially be happening is it's going into low voltage because of current draw or hitting thermal since ab run hot...but I could be way off here...it's just an idea
No, the amp doesn't go into protection mode with the speaker disconnected. Let me guess, bad speaker.Disconnect sub and see if the amp still goes into protect.
Could be a shorted coil, especially since you may have been overpowering the sub.No, the amp doesn't go into protection mode with the speaker disconnected. Let me guess, bad speaker.
I don't know the model of your amp, but seen this video of a SSL 1500 and it doesn't even put out 200w at 2-ohm.
Could be a power issue, power or ground wire (even the connectors on the wires), shorted speaker wire, too low impedance for amp, a bad amplifier, or a bad sub. Voltage measurements can help, resistance measurements as well to look for a short at the speaker / wire or excessively low resistance in a coil. Most of this testing is fairly quick, but troubleshooting the exact issue might take a bit of work. I'd lean towards wiring issue or bad amplifier, but it's all a guess at this point.
As mentioned already, the actual impedance / specs of sub could help here, and the exact model of the amplifier as well.
This video shows an SSL 1500 amp not even close to its ratings.
