i turned my car on, music played for about 2 seconds, than my bass cut out. im running a rockford 500.2 amp, and a 1/2 farad rockford digital cap...the capacitor is reading .1 on the display, and it first read at like .8, than went down. obviously it is suppose to be reading at least 12. Has it discharged? all of the connections to it are secure, I just havent looked at the connections to the amp yet. but would it matter if anything is loose on the amp because the cap is still not reading on the display at least 12..
