soundstream15 Posted July 26, 2013 Report Share Posted July 26, 2013 My friend is having a issue with his system, he texted saying..once my system warms up and I turn the volume down my bass cuts out and then I have to crank up the volume to get them back on His voltage doesn't drop below 13.5. This is what he is running. This is all the info I have.

Bradprobert Posted July 26, 2013 Report Share Posted July 26, 2013 First he needs to check his rca's to make sure they are not loose. Other than that, it could be the output of the HU or the input of the amp.

I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . Link to comment Share on other sites More sharing options...
Nick580 Posted July 26, 2013 Report Share Posted July 26, 2013 Just throwing this out... when the system warms up the overall voltage drops. When he turns the volume down perhaps this newly lowered voltage of a "warm" system becomes to low for the input voltage going into the amplifier. This in turn cuts the subs, but when voltage is the increased by increasing the volume knob on the HU, the subs begin playing once again. This is only a theory so if im wrong please correct me Link to comment Share on other sites More sharing options...
Barnett 313 Posted July 26, 2013 Report Share Posted July 26, 2013 Hi, I was going to say the same thing the receiver, I had the same thing happen to me. I paid all that money for a Soundstream VR-931RB, hook it up played for 3 days and the volume just cut out. sent it back and got a new one, that fix it.

kickass audio Posted July 26, 2013 Report Share Posted July 26, 2013 I had the same thing happen to my DC 175.4 and I originally had switched channels on the amp and it fixed it, then it came back again and I had enough with that amp and ditched it and replaced it with an sax 200.4 and it works fine now. I still don't know what is wrong with that 175.4 but it was the amp that gave me that type of problem. 2004 GMC Envoy1 XS power S3400 batt under the hood and 4 XS Power D3100's battery installed in the rear by the amps0 gauge power wire from front to backAlpine iva-w205 touchscreen dvd/cd/mp3/ipod/am/fm/gps headunitSundown Audio SAX-200.4 amp for my mids and highs8 gauge speaker wire from amp to woofer270 amp Mechman AltRockford Fosgate T1652-s component speakersRockford Fosgate 3Sixty.2 sound processorRca's from Rockford Fosgate and Monster Cable14 gauge speaker wire for the mids and highs1 18" Ascendant Audio SMD Dual 1 ohm with custom Black & Blue carbon fiber and hand signed dustcapBox: 5.66 cubic feet net volume box tuned to 30.13Hz with 1.5" wide wooden dowels and 1.5" thick baffle1 DC Audio 5.0k amp wired to .5 ohms nominal with an imp rise of 1.35 ohms for the single AA SMD 18"Future Vision 8000k 50w bi-xenon projector HID's with 4300k 35w fog lightsLink to my build: Buildupdates/progress Link to comment Share on other sites More sharing options...
