it far away from the header/exhaust.
3. Connect it on the Positive (+) terminal of the battery and secure the fuse
holder in an accessible area using screws or zip-ties.
4. Once all is connected, put back the seat and make sure all connectors are
plugged-in so you can re-connect the negative post (Ground) of the battery.
5. Turn on the Radio and check sound making sure that all speakers are playing,
then adjust the amplifier’s gain and crossover point to your preference.
