symptom | possible cause |
distorted output (cont’d) | speakers are blown |
poor bass response | speakers wired with wrong |
| polarity causing cancellation |
| at low frequencies |
| crossover set incorrectly |
battery fuse blowing | impedance load to amplifier |
| too low |
| short in power wire or incorrect |
| power connections |
| fuse used is smaller than |
| recommended |
| too much current being drawn |
| short in power wire or incorrect |

action to take
check system with known working speakers and repair or replace as needed
check speaker polarity and repair as needed
reset crossovers referring to the
check speaker impedance load, if below 2 stereo or 4 mono rewire speakers to achieve a higher impedance
check power and ground connections and repair as needed
replace with proper fuse size
