dual sub outs on head unit to monoblock cause damage?


Recommended Posts

i had a jvc m740bt head unit. it had two outputs for sub channel. connecting both to my orion xtr1500 caused the internal preamp of the head unit to kick out during high output. it also seemed like this damaged the output from the jvc permanently. i was getting a super dirty signal on the oscilloscope after this happened. i read that monoblocks often run their inputs in parallel. could feeding two discrete channels into one input cause damage to the head unit?

It shouldn't but why did you have it hooked up that way that's 2 different signals getting jammed into 1 the monoblock is designed to compensate that into a mono signal

it was done at a local shop. i didn't question it. i only noticed when upgrading to a sundown sia 3500 and it still has dirty signal/ amp had low/clipped output. im using single rca now and just put a new head unit in. just trying to figure out what was causing my issue. and hoping plugging my 3500 into that head unit didn't damage the new amp.

Headunit might just be bad I work on cars and like mechanics say just cause it's shiny doesn't mean it works

Turn all bass boost off and make sure when you check it that the eq is flat
