Rockford Fosgate P300-12 Punch 300 Watt Subwoofer Review + 8 AWG Amplifier Install Kit

Driving around was never as good as it should’ve been, the low end bass in my car was just lacking. After weeks of research, I landed on the Rockford Fosgate P300-12 Punch subwoofer. This subwoofer is powered and does not need any external amplifier to work. It only needs two wires going to the battery, and two wires going to the head unit or line out converter for Mazda vehicles with a TAU.

As you can see in the picture, the trunk just barely fits this beast. The sound on the lows is clean, and hits just right. You would be amazed with the sound and quality of an enclosed sub this size with no external amplifier. The connection to the battery was made using a special wiring kit called the Rockford Fosgate 8 AWG Amplifier Install Kit with Interconnect. The main wire came with a 60 amp fuse and fuse holder. Just look at how nice the fuse fit onto my battery!


Overall, for much less than the cost it would have been to professionally install a passive sub with a dedicated amplifier, the Rockford Fosgate 12 inch subwoofer really impressed me.

Any questions, let me know in the comments below!

  1. I am wondering if the change with the sub-woofer will degrade your battery performance? Is there a separate button to turn ON/OFF the sub-woofer so it doesn’t drain much battery when my car is idle or not started at all?
