3. check signal lead
4. check gain control
5. check Head Unit volume level
6. Clean contacts on fuse holders
Check point: Is the overload LED illuminated?
Cure : check for speaker short or amplifier overheating.
二.Symptom: AMP not swithcing
Check point: No power to power wire
Cure : Repair power wire or cnnections

Warning :
Investigatie the layout of your automobile thoroughly before drilling or cutting any holes. Use extreme care when you work near the gas tanks, gas or hydraulic lines, and electrical wiring. Always make sure the power amplifier is securely mounted. Mounting the amplifer securely to the automobile will prevent damage to that car or injury to a person,particularly in the event of an accident.

Don’t mount the system so that the wire connections are unprotected or are subject to pinching or damage from nearby objects. The +12V DC power wire must be fused at the battery positive terminal connection. Before making or breaking power connections at the system power terminals, disconnect the +12 wire at the battery. Confirm your head unit and /or other equipment is turned off while connecting the input RCA jacks and speaker terminals.

If you need to replace the amplifier fused, replace if only with a fuse identical to that supplied with the system. Using a fuse of different type or rating may result in damage to this system which isn’t covered by the warranty.

Note: setting SPL at 85db in long term will damage your hearing, please kindly note.
