Install issues with shop

[chawski 10+ year member]

So now that I know a thing or 2 about installs, I was checking over some work that was done a few years ago in my car and have run into some red flags that piss me off to think I paid someone to do it. For starters not a single wire was soldered/butt spliced/screwed. They simply wraped the wires around each other and covered with electrical tape. My speaker power was definately suffering from the bad connection, but none the less, it was a pretty easy fix. I then noticed that instead of sending a dedicated power wire for each amp, they spliced a wire from the positive of amp 1 to positive of amp 2. They did atleast run separate grounds

My question is regarding the power wire going to the second amp. Am I getting less power to either/both amps because of this or is splicing an acceptable method to prevent the need for running 20 feet of cable through the car? Its something that I can easily do now myself, just wondering if its worth it? Unfortunately the shop has since gone out of business, so I cant take it back.

I would purchase a distro block and run the power that way.

depends on what size wire and how much amp draw your amps are using.

just to make sure i understand correctly...

The distribution block would attach to the single power wire thats already ran and "T" off the 2 power wires to each amp? To clarify, my system is by no means a competition setup, just a daily driver. I think my sub amp is 400-ish watt per channel and the 4 channel is 100 each. I believe it is 4g wire

you said this system has been together for several years , with the power hooked up that way, if the connections are solid and not dangerous, then i would say leave it. i would be more concerned on how they did your grounds and if your under the hood connections were done correctly, did they put another ground wire on? probably not! but they should have either criped or solider and taped your other connections, i have even seen bandaids used in the place of tape!
