Hello I am a owner of a new to me 2006 Toyota Sequoia SR5 4wd. Like many other my jbl factory speakers sound terrible if I’m playing anything with bass. I recently came across a kit From a company called Simply Speakers to replace the deteriorating foam in my front driver and passenger side jbl 7 inch speakers. After unscrewing the speaker I’m having issues detaching the small black electrical connector Clip at the rear of the speaker. Is the clip removable or are is it soldered in place. Clip seems quite fragile so I didn’t force it. Thanks in advance and I look forward to being part of the Toyota nation family.
