Hey everyone
I just purchased Infinity Basslink to compliment my non bose system in the 97 max.

I have a question on high and low pass filters. I went as far as installing my own rear deck speakers so go easy on me, I'm a noob.

My rear deck has Kenwood's

Front Speakers are still crappy stock.

I want to prevent any sort of bass from coming into the rear deck or front speakers as well as prevent any non-bass sound from being processed by the subwoofer.

Considering my setup which one of these do I purchase:
