Sorry I’ve done a lot of my own installs nothing fancy but I know enough to get buy. I have 2 subs 12” in a band pass box run by a 2/1 580 watt amp. I’ve never had a box before with 2 subs and only 1 speaker input in the back. The stero sounds fine but out of nowhere the subs just stop and the green light on the amp with either remain green. Sometimes turns red and sometimes goes off completely . Sometimes it’s days with no issues sometimes it’s 4 times a day. There some noise in the subs as well ( hum pop). The subs are 4 ohms and since I only have positive and one negative speaker posts in tbe back of the box I have the amp bridged which i think is wrong. Here are some pics. Finally my ground may be an issues it’s grojnded to a metal plate no paint which is mounted to the body which has paint . Any tips?
