Hi guys. putting together basic system. alpine 4 channel 120w rms 300w peak and alpine 500w rms 1000w peak. want to run 4g from battery to d block in trunk and 8g from there to amps. I have two amp kits. 4g and 8g. Im just wondering about the fuses. the one kit has 80amp fuse. can I use this from battery? one amp has a 25amp fuse , the other two 30 amp fuses. thanks for any help.
