Sub-woofer standard on base models

I'm tired of not being able to hear depth using my stereo the one thing that is missing is a Sub or Low Frequency channel. I think it would be a great thing to have in all base model vehicles and can get stronger in the level of opinions Ford offers.

The issue being it would raise the base model price and the client base for those models are usually looking for bare bones and a cheap car payment.
