Have you inspected the speakers? there is a foam surround that attaches the cone to the frame which can rot out over time and you'll lose all bass from that speaker. You can either replace the surround or the speaker (I've done this on other cars and my home stereo ). To test if the speakers are in good shape, try hooking them up to a second sound system (home stereo/boom box?) and see if they sound normal. I'd also check to make sure that you have a solid ground and speaker wire connection. To test this out, running a direct wire from your amp output to the speaker. At this point I'm thinking it could be wiring (ie weak ground) or bad speakers.

Embarking on a literature review journey has been transformative, and seeking "Literature review writing help" has been my compass. It's not just about mastering the art of synthesizing existing knowledge; it's a profound exploration of ideas. This invaluable assistance has not only refined my academic prowess but also played a pivotal role in honing my "how to improve communication skills" https://essaypro.com/blog/how-to-imp...er-interaction quest. Through meticulously crafted reviews, I've learned the power of clear articulation, creating a seamless bridge between ideas. Every session feels like a collaborative dance with words, fostering a deeper understanding of effective communication. Grateful for this enriching experience, it's not just about literature; it's about refining the essence of expression.
Thanks for the information!
