Celica Forums General Discussion Exterior help w/ sound system!

Hey one question i have my aftermarket headunit and my install kit to put it in my gts 00, so i went to brandsmart to get the wireness and they told me i have a buit in amp in my car that i need to bypass in order to install the headunit. That is almost impossible to do it by myself, and costs like 100-120 to be done professionaly... is that true?????

in short, no

Places like Crutchfield have harnesses, brackets, speaker adaptors, and anything else you would need to self-install plus they have detailed instructions specific to your car make and model

It's actually relatively simple to bypass the stock amp.
