These are great mid range speakers with one of the cleanest sounds that I have heard in a long time! The lows are typical of small speakers, but the mids and highs more than make up for it even if you don't run an amp to it.

Sounds a million times better than my stock Porsche 996 set up and I only had to do a little bit of modification.

i have a pair of these hooked up to a crunch p900.4 and they sound great. i have them set up so they have the high pass filter and they sound crystal clear. i tried letting them bump a little by switching them to no filter but they couldn't handle much. i didn't really expect much out of 4 1/2 in. speaker anyway. overall, if your looking for a decently priced speaker to fill in the highs and mids in your system, you won't be disappointed with these.

Easy to install, sounds great, love the way they sound.

I've mounted these in the front of my 126 Mercedes, they sound good but I've noticed the plastic connection rattles inside the dash sometimes.

The sound is very clear and the look is great.

I used these to replace factory 4 inch rounds for my front speakers and paired with Infinity 462.9cfp for the rear. They sound nice for radio, and mellow songs. However, they get overworked and bottom out while listening to pop, hip hop, and country with a lot of deep notes. Would propbably be very nice if paired with larger speakers for the lows.

Used them in my jeep wrangler and then made a custom home speaker system with them. Great for little speaker installations.

I've been using these speakers as midrange and tweeters in my old '87 Corolla for about two years now, and these little guys really scream! They're kinda bright/harsh at high volumes,(so if you are into that, these are the speakers for you) however, with some equalizing you may get a really good result. With correct crossover settings, these speakers also handle a great amount power without distortion. Crystal clear sound with lots of details. So, final comment: I really recommend these 4" speakers. They are a little "bright-sounding", but damn, they are pretty nice speakers as well :)

I can't believed they sound like 6 x 9

I used these speakers to replace my old and worn out nakamichi speakers in my Sc400. I purchased two sets of these and am glad I did! For the buck these things are quite worth the money! The only complaint I have is that they have terrible lows but that's alright as long as you have a subwoofer to provide it. Anybody that has asked me about speakers i refer them to these and will continue to do so.

These speakers are super loud, after a while with the volume up i just turn it down because i feel its gonna hurt my ears, great volume and treble but very poor bass, I have these connected just to an aftermarket stereo (clarion vrx575usb). 2 minutes to install.

this is one of the loudest and clearest four inch speakers i've ever heard and believe me i went through a whole bunch of other brands like kicker ,alpine,polk audio,sony and pioneer and these infinitys are by far the cleanest sounding and get super loud without distorting.

This is a very good product for those who love quality sound
