THA WORK F***ING AWSOME TO

It's refreshing to find a product that does exactly what it claims . Installed these in my f150 reg cab truck . Not only did they improve sound stage by placing the bass now in the rear of the stage where it belongs but also freed up power being robbed by low frequencies where i didn't want it . Thanks 👍

Made no difference in frequency response. Speakers still played low bass.

Must have to make your mids to crank.

Very easy to install and save my door speakers from all the low bass frequencies. I returned them for 200hz to allow the door speakers to get a little lower. These totally do what they say.
