Are you unhappy with your factory speakers or are they making a scratching or crackling sound? This happens when moisture in the doors damage the factory paper speaker. Speaker failure in the GTR is very common, especially the older it gets. Even with undamaged speakers, they can often lack the clarity you would expect.

This plug and play kit is designed to replace the font speakers in 2009-2020 Nissan GTRs and comes with everything that you would expect for a drop in solution. This includes a harness that is the correct length, all ends properly terminated, and an OEM style connection to the factory stereo. Speakers are flush mounted in custom made GTR specific plastic brackets. Not only do the brackets look great, but they are very strong and will never be damaged from moisture since they are plastic. All connections are one-way, so there is no risk of accidently reversing polarity. An hour and a half per door paired with this harness will result in an excellent sound improvement and reliability into the future.

The Hertz Mille Pro 3-way component kit offers a warm and balanced sound with good mid-bass response. The signature V-cone enables excellent sound dispersion throughout the GTR cabin. Full cast baskets provide for a refined finish and support enhanced structural rigidity.

  • 2 Hertz MP 165 woofer drivers mounted on custom 6.5” in-house made plastic adaptors
  • 2 Hertz MP 70.3 mid-bass drivers mounted on custom 3” in-house plastic made adaptors
