scobar Posted May 8, 2014 Author Report Share Posted May 8, 2014 I'll hopefully get to it tonight. I did order a different amp that does have a smaller footprint so I can have my rear seat in correctly. Link to comment Share on other sites More sharing options...
never knows best Posted May 8, 2014 Report Share Posted May 8, 2014 Turn On/Off Thump Turn on thump can vary from a slight pop to a mind shattering, teeth rattling BOOM! This thump is caused by the audio circuitry stabilizing when power is applied. Most amplifiers and source units have muting circuitry that lasts a couple of seconds to allow these fluctuations to subside before passing a signal. However, if the amplifier un-mutes before the source unit or any other accessory, you better watch out. Here are some things to try if you have turn on thump. Verify that the amp has a good audio ground reference. Dont install the system so the amplifiers can be switched on when the source unit is turned off. If you still have thump, add a turn on delay module in line with the remote turn on wire to the amp. Link to comment Share on other sites More sharing options...
scobar Posted May 8, 2014 Author Report Share Posted May 8, 2014 Ok, pulled rcas. I can turn the deck on/off and no pops. I can hear the relays turn on, first deck, then center console and then amps. I have an audio control matrix in the center console with a relay that feeds the amp remotes, and a pioneer screen deck(forget the PN). Everything was set with a DD-1 Link to comment Share on other sites More sharing options...
truthsayer Posted May 8, 2014 Report Share Posted May 8, 2014 Sounds like this was discussed in another post. Anyway, sounds like the rca connections on your amp has an internal grounding issue. truthsayer Link to comment Share on other sites More sharing options...
scobar Posted May 9, 2014 Author Report Share Posted May 9, 2014 I should have mentioned with the deck on giving the amp remote power there is no thump either. Sorry low blood sugar. Link to comment Share on other sites More sharing options...
