  What can one say about this Sub from Hertz... it's a brand new design, shallow and designed to work in small enclosed boxes. I use it with the following Polish box from Basser.pl which is specially made for the 2004 Ford Focus MK1 Hatchback. https://sklep.basser.pl/en/fit-box-enclosures/302-fbford01-ford-focus-mk1-fit-box-subwoofer-enclosure.html and because it's quite powerful (500W RMS at 2 Ohms, there is also a version at 4 Ohms, the 1000W incorrectly mentioned by Skroutz as RMS is Peak Power, not RMS!) I power it with 300W RMS at 2 Ohms from the legendary Audison SR5 amplifier which is not easy to find anymore I think. See specifications in the image below. I must emphasize something incredibly important, never install such powerful subs in your car without some soundproofing material, vibrations and bass loss are significant! I covered the entire trunk with many sheets of Dynamat Xtreme with the special kit for the trunk, this one here https://www.skroutz.gr/s/20210771/Dynamat-Xtreme-Trunk-Kit-%CE%97%CF%87%CE%BF%CE%BC%CE%BF%CE%BD%CF%89%CF%84%CE%B9%CE%BA%CF%8C.html

  The result is AMAZING! The Sub delivers such strong, clear, and powerful bass that I can't describe it with a simple review here, you have to hear it! I feel a powerful acoustic force coming from behind and spreading throughout the cabin, captivating you, penetrating you, and making you want to hear certain tracks over and over again! Installation plays a VERY IMPORTANT role. You must follow the specifications provided by Hertz regarding the box volume. It doesn't require many liters, the new shallow design as I mentioned also works in smaller boxes. However, check the specs and make sure you have more than the minimum required. In combination with the soundproofing of Dynamat (it costs but it's worth it!!!!!) the result is phenomenal.

  The Sub was installed at the end of September 2022 and since then, I have been constantly looking for tracks with powerful and deep bass to test it continuously. Dance music, Rock, live acoustics, everything is elevated thanks to the sub and every car journey takes on a different meaning, if you enjoy music at moderate to high volume, if you push it too hard it can become dangerously loud and requires attention not to damage your hearing. I give it 300W RMS and it rocks, imagine if I gave it a little more, e.g. 400W! The amplifier doesn't output it though. I have no vibrations thanks to dynamat, vibrations are NOT a good thing as some may think, they essentially reduce the speaker's performance.

  It comes with the protective grill already mounted, VERY important because in other subs you have to buy it separately and it costs 30 to 40 euros.

  It provides a hard cardboard template with its dimensions for custom box design as well as mounting materials of course.

  For 300 euros (now the price has dropped a bit) it's simply the perfect buy in its category and it has also won an award for the best Subwoofer product of the year 2022-2023 from EISA! Check it out here https://eisa.eu/awards/hertz-mps-250-s2-s4/
