Nice box

The following review is for NE122P, which is a part of the bundle you are viewing.

Pair with the right woofers and you will be happy. Wouldn't put anything crazy high powered in it. Box is tuned to 38hz. Sounds good, it doesnt hit the super lows in rap hard, but 95% of songs sound great. Used in a 2020 Ford Fusion. Fit with no issues.
