A lot of people come in thinking that replacing their speakers first will make their system sound better. They are surprised to learn they will get the opposite effect and that replacing the head unit first is always the best option as it puts out more power, thus making the stock speakers reach full potential.
This is why I combed through the speakers on PartsExpress's website. I haven't personally demoed the TB speaker that I recommended but given the speaker's specs. and the power that the OEM amplifier provides, it was easy to see that it was a good match.
