No power to my subs

When I connect all terminals to my amp the led light won’t come on.. i had gain 1/2 wat was at 80 hz on low pass radio volume was 20 out of 50 so not loud... was hitting my 2 12” 2000 pioneer premier subs they were moving normal all run to 2ohm and it just stopped working won’t light up .... no bad smell from amp or subs anyone have this issue before or how to fix

depending on the the amp make, it might be a resistor or a fuse that burnt in the grounding circuit, explaining the engine noise

has your sub blown, this just happened to me, as soon as i hooked up a differant sub it went back to green the light and worked fine.

( I am assuming your amp does not turn on)


You will need a test light. You can get one at a hardware store for a dollar or two. clip the end of the test light lead to a good ground, and touch the needle to the red 12v constant that feeds the amp. If it lights up then you are getting power from the battery. Next, turn the car and the stereo on and touch the needle end of the light to the small blue signal wire that goes into the amp. This should light up as well. If either of these don't light up then the wiring is faulty. If they both light up then we need to test a bit more.

First make sure your ground wire is tight at both the amp and the car body. It should have metal to metal contact with the car (no paint on the contact area)

Check the 12v wire running from the battery to the amplifier. Also the sony explode is a garbage subwoofer compared to the Alpine.. sony (they say 1200w max but its more like 100w to power the thing) Amp could be going. Is the amplifier hot when running. If there is a burnt smell comming from the amp, its the amplifier

ya i would say its not grounded right

make sure the turn-on wires wasn't accidently disconneted

check when the amp is powered on the is a beat on start up -if yes then chk the input conetions of amps if no then chk output connetions of amp.

You may have a problem with the power source feeding the amp. You need to check the voltage across the amplifier's B+ and ground terminals when the amp is playing/cutting off. If it's dropping below ~11 volts, you need to determine why it's dropping so low.

check your main ground, if possible try to read voltage across making sure 12-14v present with load and some signal.
