Subwoofer Install

Are you going to build a box on that side? I have been thinking about building a box over the right small storage bin for my Audiofrog 10". The recommended seal is .5-.75 cubic feet. I need to get measurements.

I got about .75 cu ft for the cubby area. This is without the little storage area. Factor in wall thickness and speaker displacement, and you’re there

In preparation for my install, I’ve been monitoring the battery voltage while the car is running/driving so that my amp tuning is correct for the vehicle.

I’ve noticed the voltage kind of jumps around from low/mid 13s to sometime spiking to 14.8… has anyone else noticed this? I know some new cars vary the voltage for what every different things, but not to this extent.

I was expecting 14-14.4 which I think is pretty standard.

I have searched for variable voltage on GMs. It looks like the Silverado trucks have it. It might be on these as well. I know it can cause issues.

I'm having issues with the Variable Voltage on my wife's car (Nissan Pathfinder). It will randomly kill the battery and Nissan says the battery tests good. I'm about to disable it on the vehicle. It's just a push clip on the negative terminal.

That is an Illinois background if I ever saw one.

My camaro did the same, ran an aftermarket amp for 6 years with no issues. Used the same amp when I had a 4bw with no issues. I have a 5bw now but haven't installed audio upgrades yet because the shop that did my installs closed.

Have a 12 Silverado and the voltage gauge moves around often. Have 2 amps from the battery with no problems. I would recommend installing a fuse before the amp. Just for extra protection.
