Very good speakers do need an amp to get the full effect.

Great speaker if you are limited to a small mounting space.

To get full potential of this speaker it really needs an amplifier or the sound is drowded out.

The speakers were fine quality, especial for the money, but they had too much midrange for my taste for the cabinets I was installing them in. Otherwise the order was expedited nicely. I would do business with Sonic again.

Ordered a set of these to replace dash speakers in 91 S10 Blazer and what a huge difference they make. had to modify the factory mountings but well worth it. Wish i had found these earlier. Sonicelectronix Shipping was crazy fast and was even the free shipping. ordered at 11am thursday morning and was here by noon on Friday. Will be ordering more in the very near future

This speaker sounds just as good as one you'd pay triple the price for! I was blown away by the quality of sound. These are hooked up to a little CPT2-400 and I couldn't get them to distort as high as I could tolerate the volume level and I haven't even broken them in yet!! Well worth the money!

I needed 2 speakers to replace the rear deck speakers of my Pontiac Trans Am. Unfortunately, 4" mid speakers are hard to come by. However, I came along these and decided to give it a try. After hooking them up to a 3 way cross-over, I must say for the size and the price, nothing can come near it. The magnet is pretty heavy duty especially for a 4" mid speaker. I play all sorts of music (hip hop to r&b to death metal) and the sound is very clear and crisp. I turned it up just to hear how loud it can get and surprisingly, there wasn't an ounce of distortion. I would say this is one of the best investments for my car.

I sell a lot of the xps-104 and customers love them. Known as 104s in Atlanta, they are widely used inside or outside of the vehicle. On My personal vehicle I have four on the outside and even in the rain they still work without an issue. The Speaker itself has a closed metal frame therefore there is nothing to worry about. As far as sound quality it sounds extremely loud and clear without any distortion. Whether installed on an amp or a radio PAxps104 is the way to go. TheAudiophiles Atlanta.

I bought these to replace mid-range speakers in an old technics stereo system, these speakers are really nice and sound wonderful even on a 30 year old record player
