I have a 2003 Highlander, non jbl sound system. I installed new speakers and they have less than a whisper at full volume. Stock speakers make sound, just not great sound.
I went to the dealership and they said there is an external amp, roughly in the middle of the cargo area.
Can that be the cause? If so, can it be removed?
