Hey guys,

Im looking to install just a 10" sub in my 01 GLS Jetta and wondering if i can hook it up to the pre installed amp ? I took the top part of the trunk apart and looked at the amp but justsaw two wiring harness connected to it but some open ends on the grey harness Is this possible or do i need to purchase a seprate amp


Thanks in advance !

 

You will need a seperate amp and head unit.

 

dont need a new head unit, you can get rca's in there one way or another
