[QUOTE="Couchsleep3r, post: 8775282, member: 684510"] Trying to troubleshoot an issue with my subwoofer/amp setup. I recently had to replace an old amp and bought a jbl amp that matches my subwoofer. The new amp worked fine for 2 months then sound became intermittent. I went to a shop and the tech found that my loc was no longer working, but because i have the option for high level he suggested I get rid of the loc. that worked for about a week, then no longer got sound out. i tested a few things and plugged directly to my phone and got no output, changing the subwoofer out didn’t work either. Jbl had me send in the amp and they ended up sending me a replacement amp. the new amp worked for about 2 weeks then one day the sub started to crackle and then output stopped. i have replaced my ground connections, and checked all my speaker inputs, and fuses. Plugging my phone to the amp gets no out put, and the amp is not in protect mode. Looking for suggestions on what may be wrong before heading to a shop to get it diagnosed. [/QUOTE]
