great value!

I knew going in that I wouldn't be disappointed and I was right. These little suckers pump!! I put them on my BMW K1600 GTL and they are louder and clearer than the stock speakers. Having owned a MTX Blue Thunder bandpass enclosure, a 10" Black Gold sealed enclosure and currently using a dual 10" 100 watt Thunderform box in my 1998 Dodge Dakota, I know the benefits of MTX products. Big or small, their products rock!!

Before you buy, know this

This speaker has an awesome sound, but of course it does, 4 ohms. It looks very appealing, and has an easy installation. BUT if you plan on running more than 15 RMS to it, I'd be careful. Even after being broke in, this speaker seems to blow very easily. I'd recommend this, IF you don't listen to loud music. If you want a decent system to show off, and are looking for a replacement dash speaker, I WOULDN'T recommend this speaker. It cannot take the abuse, even when you run next-to-nothing power to it.
