I didn't want to do this, but this is the last time I'm going to respond to the same thing. At this point, it looks like you are just regurgitating your same answers, and trying to justify them with assumptions. I'll throw a few out at ya.You must have missed when I prefaced with "Only issue I see is those bare power cables". It is in my original response to OP.
Lol, I see your point. Let me then ask you; why would you assume the amp was not tucked under the seat before the picture was taken?
FYI, economy electrical tape is rated up to 600v.
Of course it is hindsight. Almost everything that everyone does is based in hindsight. Hindsight and experience walk hand in hand. Do you think OPs installer knew how to connect that amp out the chute? No, someone taught him. Seeing someone do it and applying logic is what made him the professional amp installing god he is today. The reason I assume everything else was done right is because OP told us all was working fine.
Well, we could use hindsight.
If OP asked for your help to install an amplifier because his old one was stolen; all you had to go by was those wires in the picture. Would you be able to figure out the wiring at a glance? Also, it is a 5 channel amp.
No, no, and no.
Yes. OP said all was working good. After the tweeter's install he could not go above "half" volume before it started cutting off. This tells me he could go almost full volume before with no issues.
I would agree with you here but I bet the speaker wiring guide is not printed on the amplifier. That means installer read the manual for guidance. Every amp install manual prefaces with safety practice. That is disconnect battery and install a main fuse near the battery
Here are the reasons of my assumptions and why I think there is little danger in this setup.inputs
