Ok so I replaced the stock radio in my 2010 civic lx with one from a 2011 SI . Same fitment everything hooked up correctly settings gone through fuses checked everything seemed good but the volume on high of 40 although working but extremely low . Only thing I can think of is do SIs come with a factory amplifier that LXs don’t and would that cause the volume to be low?

So would that cause the volume to be that low ?

Thanks for the information , installing the correct radio was the idea that’s why I asked for the help..

Another question would be the factory amp from an si would it be able to hooked up in an lx ?

Thanks for the help , guess I’ll leave it as is until i get another set up just looking for funtianalty
