Amps power on but no power to speakers/sub


Recommended Posts

Posted

Driving me crazy. I have a 4ch amp and a mono amp. The 4ch amp is wired to my front door speakers via speaker wires i ran. Mono amp wired to sub. I'm using a pioneer avh-p2300 headunit which has 2 rca outputs (fl,fr) and (swl,swr). Have everything wired up both amps have power/14 volts running to them. But i Cant get sound to my sub or speakers!! Using a mulitimeter i get no power out of either amp's speaker outputs. What gives???

I have like 3 pairs of rca's that I tried on each amp...none of them changed the outcome. Looked over my HU manual a bunch too to see if my HU isn't sending the output to the amp. Can't find any setting like such though.

Hey stupid. I got your report. You cant type a coherent sentence but yet think you can run this much power? You cant even hyperlink on the internet. You have no mention of power upgrades. You just want dat big boom dat make dem bitchez panteez drop. Next time you report someone make sure the one getting the report isnt the one you reported.

How is your amp on but no power is at the gnd and power terminals?

Legal TL scores145.6 on the dash sealed up in the low 40hz area with the port out145.5 on the dash sealed up @30hz with the port inless then 1k clamped on a 3.5k!

Why would you EVER WANT flex?
huh?...flex is what can make the lows lower and more air being pushed correct?

have you checked the voltage on the rca wires with the multimeter? and also right at the back of the radio? Make sure you have power going out

Do I check with the MM on DC volts? I tested them with the MM on "dc 200" and got nothing. Nothing from the rca's and nothing from the rca output on the back of the head unit.
