10" Seas L26ROY subwoofer first test in my car with only 100w rms

The first test with my Seas car subwoofer! :D I just nearly finished the enclosure yesterday, theres still more stuff coming to it, like a front grill and so on. The Subwoofer is not actually powered by a caramp right now and its not wired up to the cars stereo. It instead is powered by my trusty Sony STR-DH190 stereo amp which works with 230v. (For testing) And yes it only has 100w RMS so 1/3 of what the Seas is capable of but it still is pretty damn loud like this. I cant imagine what it will sound like with nearly 500w rms. In the next few months, I will wire it up properly a Groundzero subwoofer amplifier. The enclosure is a Transmission line enclosure with a slot port the same diameter as a 5.5“ normal rounded port. Its tuned to 26hz, I will post a more accurate video soon. The Seas even hits 25hz really loud, its not comparable to any subwoofer I had before, its crazy loud for a 10“! The driver is rated for 250w RMS and 500w max, so it propably could take 300w for
