You make a good point. I recognize that I am learning on the job with regard to car audio. That includes a certain degree of trial and error. In retrospect, I should have taken a more comprehensive approach to this project from the start.

I don't listen to music at extremely high volume, and my musical taste does not include music with booming bass. I hope that will help avoid a serious problem while I'm assessing the results of the first stage of this upgrade. I appreciate that hope is not a plan. If I hear or see any evidence of stress on the system, I will turn it off until I can address it.

My task for next weekend is to repair the HVAC dampers that have been spewing foam through the vents for a couple of years. That job involves removing the head unit. While I'm in there, I plan to add the wiring for an amp that will drive the door speakers off the head unit's subwoofer channel.

Perhaps someone who has approached this upgrade like I did can weigh in with information based on their experience.
