do i need to fuse?

Well I got my second battery in the rear of my car right next to the amp. The distance from my battery + to amp is very short I would say 12 inches give or take a few. Since it is a very short distance to my amp do I need to fuse it?

i would personally as you have a constant source there now so if anything were to happen say a dead short in the amp (unlikely but possible) theres no disconnect between there besides the power lead itself which i assure you takes much more heat to burn through. just from a strictly safety stand point yes yes yes always use fuses between batteries and amps keep it greasy

When in doubt fuse it! Easier to replace a fuse than explaining why your vehicle burned to the ground. The fuse is to protect the wire and not the amplifier.

Always fuse battery connections. The purpose for that fuse is to protect the wire, which can cause a fire is grounded or more current that the fire is rated for is drawn though it. No exceptions. Post some pics of you install afterwards too, we always like to see completed and progress pics. GL EDIT: I had to take a leak break from my post and audiocableguy actually said what I did first.rtfm

Heres a pic as you can see the distance is VERY short I am having trouble finding a fuse location. And as the wire being really shorts its hard to get it to bend so it can securely stay in

I know that there must be a hidden fuse on the wire that goes to the front of the car.

ha ha ya there is a fuse its hidden right behind the battery my main concern though is do i need to fuse it coming off the + into the amp as you can see it is VERY short

Here to make you happy! You can see the little guy right behind the battery

Just checking.   Are there fuses built into the amp?   If so I really do not see a need for the fuse on the power wire.  Of course if there are no fuses on the amp you need to protect the amp.

ya I am not exactly sure I dont see any fuses externally on the zx2500 like you see on the other zx series lemme look up to see if there inside
