crescendo 100c4 just got it

[R3B3L 91 10+ year member]

so i just got my new 4 channel crescendo and i was cruising around listening to it and what not. stopped at the gas station then it wouldn't turn back on. i realized that it was getting pretty hot. checked all my connections and seemed good. still no go. got home turned my car off and back on and its working but it still seems kinda hot. any ideas why it would get hot? i am running 4 gauge wire on it with a 60 amp fuse, should i get a higher fuse? thanks for the help

edit- also this is powering two 6.5" alpine on my door and two alpine 6x9 on the deck. both are type r 4 ohms

You probably don't have the gains set correctly.

Your fuse is also too small. The inline fuse should match the ampacity of the cable. It's not there to protect the amp, but it's there to protect the cable.

This is, of course, assuming the amp has on-board fusing already.

It sure does, checked to make sure before I said anything.

kinda new how would i go about setting the gains, start low and go from there?

would a 100 amp fuse do the job or like a 120?

120A will be fine.

Care to expand?

Fuse is there to protect the EQUIPMENT not the wire. If your not pulling over 60 amps, then sure why not use a 60 amp fuse? oh wait because its to protect the wire not amp. Hmmm so running a 60 amp fuse instead of 150 amp fuse will HURT the wire? Thats strange because hes pulling less than 60 amps...

Never said it was going to hurt the wire by running a smaller fuse, but an inline fuse @ the battery should be used to protect the wire itself from carrying too much current. If an amp has its own integral fuses, then running an inline fuse @ the same rating/lower is simply redundant - this is obviously different if the amp DOESN'T have integral fuses. In every other case, though, you want to run a fuse that matches or is lower than the ampacity of the cable, while greater than the total current draw of the system (duh). But the main purpose of that first inline fuse that comes off the battery is to prevent the cable from carrying too much current that would otherwise start a fire.

But if he gets a bigger amp that would blow that 60amp fuse, then he'd have to buy another, larger, fuse. Fuse it once at the amount that the wire can handle, and you won't have to change it again until you upgrade your wire to 0gauge(or use an amp with no fuses that isn't going to be protected with a 120-150amp fuse.

so how do i go about setting my gains? i just bought a new fuse cause no where around here carries what i need since its a maxi fuse i can only go to 100.

**** better not be the amp. I was planning on getting one very soon...
