Hi I am building a portable stereo with the YJ TPA3116 2.1 digital amplifier 2x50w 1x100w with 2xtweets 2xsubs running 24v DC with bluetooth.When I turn it on I get a loud pop from the subs more upon tuning on but,happens off too.I tried to troubleshoot it by disconnecting one sub/tweet, used a different speaker,turned volume all the way down but,it's still there.Did I just get a bad amp or blow something in the process?When it's on it sounds good.Can I mod a cap or something?I don't know if this has an "anti-pop"circuit?Any input would be helpful.Here's a pic of the amp.
