Watch a full tutorial as a 2022 Toyota Corolla will have a 4 channel amplifier and DSP installed. We will be installing our amplifier under the driver side front seat and integrated to the factory audio sound system.
NOTE: Our corolla was not equipped with the upgraded JBL amplified audio system. IF you have JBL, you will need to bypass the JBL amp with the harness linked in the description below for your audio signal.

What Max volyme on headunit did u set? Did it distorsion? 45,46,47? Or Max

[@jjgonz98]

I have a 2022 Toyota Corolla SE and I used a SMD DD-1 and playing 1000hz at -10db it starting distorting at about 52. I don’t even listen to my speakers that loud either.

@@jjgonz98 ok. Did you have any bass rolloff? What volym did it start if?

[@jjgonz98]

@@fw1367 honestly I’m not too sure or how to tell with the SMD if there is a way. I did install a LC5i Pro into my system. I currently do not have a subwoofer (will be coming in the near future) only a 4-channel amp

@@jjgonz98 ok. My rear Chanel is so low volyme and allmost no bas frequense. So i Will clone front Chanel to a 4-ch amp.
