New gear, fuses and speaker wiring?

Streetlights

Hi All.
New to the forums and just picked up some gear. Planning to do a self install but am a noobie.
I got a PA 5000.5 amp to power a front and rear set of MM6501s, and a DVC1240 sub which I plan on running at 2 ohms. Pioneer nav head unit on order.
I know that 4 awg is recommended for the amp. I am planning on installing the amp under the front passenger seat so the wire runs shouldn't be too long.

What fuse or circuit breaker size should I use from the battery to the amp?
Any other suggestions or issue's with this set up.

I usually under-fuse. My RF 5 channel has 100 amps worth of fuses but I've got an 80 amp in my inline fuse at the battery. I'm going with kick panels this season so I'll be adding my Polk 330 amp which will make total max fuses 120 amps so I'll move up to a 100 amp fuse at the battery.

You're not going to draw the max amount of your amp's fuses unless you're running at full max load which you're not so you're not going to miss out on any amperage and by having a slightly lower fuse at the battery, you're guaranteed not to hurt your amp because the inline fuse will pop before you get to the max rating of your amp. And usually the inline fuse is easier to get to and replace than the one in your amp.

Okay thanks for the info. The amp has two 40 amp fuses on it. So I will look at getting a 70 amp fuse to put inline at the battery.

You may not find many 70 amp fuses out there so if you don't, there is nothing wrong with going with an 80. I under-fuse a little more for convenience and an extra safety precaution but it's not a requirement and won't hurt anything if you go with an 80.
