Very loud

I mounted a pair of these speakers combined with a pair of 1.75" grill cover tweeters, and even at low watts their loud. I have a military Humvee witch is very noisy on the inside. And I can here these speakers clearly even at low watts (around 10- 15 watts). I would highly recommend them. Thanks Frank

PRO-ZXI 6.5" Mid-Range Bullet Loudspeaker Neodymium/Ferrite Magnets | 300W RMS 4-Ohm

Quality is A 1

First off let me say these speakers I purchased are 4 inch’s. Installed in my bmw f30 and let me say, they fit perfectly. I had to do a little custom bracket but nothing crazy. Amazing sound and clarity. Appreciate your support and help with these speakers. I’m satisfied and 100% would recommend to anyone. I believe these are the best on the market. Can’t beat the quality and prices. Thanks again DS18.
