not enuf power?

[planet audio 10+ year member]

Ok now i have just installed a distribution block as recommened in my earlier thread. (see pic 1) Now my PA amp, the one on the left, just switches back and forth from normal to protection mode. (see pic 2) is this just an issue of not enough power getting to the amp? the kenwood amp works just fine. would a capacitor fix this?

I highly doubt a capacitor would fix this.

Did the amp work before without the distribution block?

No a capacitor would not fix this problem...

It could be a multitude of things, but I would start by checking the voltage of the powercable at the amp with a DMM and see what kind of voltage the amp is receiving; if it is less than ~11v then you have a problem. It also could be a ground issue, make sure your ground spot is sanded and bare, also be sure you have a matching size ground cable to your power cable.

Also, is that distro block splitting an 8 guage into two 4 guage cables?.....

that power wire looks a little small!

have you done the big 3 upgrade?

The block is suppose to go in the REAR of the car and you connected what looks like two 4 gauge cables to one 8 gauge wire to your battery. With that set up, if BOTH amps fuses total over 120A you need 2 gauge or 1/0 run to the back THEN the distribution block. What you did wth the block under the hood is worse then before.

your setup is backwards. You went from a small wire (looks like 8 ga) to two 4 gauge. The amount of power you can get is only as good as that 8 gauge wire; its a bottleneck for power.

The amp worked by itself before i installed the kenwood amp today. it is a 9gauge leading 2 4 gauge wires to the amp. but the amp did this before when i had both 4 guage wires running directly from the battery.

You should find another grounding spot for the amplifier.

Then you should fix the distro block situation, it isnt something you should cheap out on...

What would that do? I have the PA amp (dysfunctional amp) and the kenwood amp grounded at opposite ends of my trunk. I just left the PA amp grounded in the same location because it worked fine until I installed the kenwood amp. Oh and I fixed the block situation.....that was a lack of thinking on my part lol!
