Hi everyone

I just purchased a 2011 Outlander Sport SE without the Rockford Fosgate system

Very happy with it but would like to know if anyone knows about aftermarket sub boxes that fit in the RF spots or ones that would fit under the front seats?

I have 144 miles on it and I bought it with 11 miles. No complaints except for the buzzy drone of the 4 banger caused by the cvt. I heard there is an updated software. Is this true??

Thanks!!
