    • Great little speakers!
Fits well enough- barely- in my 1990 geo prizm. The old speakers were rotten and driving me nuts! Since I picked up the car dirt cheap I wanted some dirt cheap speakers, but I'm picky about sound, so didn't want the new speakers to suck... Yeah, tough situation... I did some research and found these. I like that they are 4 way. They sound great and they're very responsive. I think I need an amp though... But overall they can't be beat for the price. update- 30 Nov 2012 To flesh out my review and provide background- I bought a Boss 612UA MP3-Compatible Digital Media AM/FM Receiver as a low-powered stereo so I could play MP3s off my iPhone or MP3 player on my commute, and some Pyle PL573BL 5-Inch x 7-Inch and 6-Inch x 8-Inch 300 Watt Three-Way Speakers for rear speakers. The stereo is great. The Pyle speakers get 1 star because one sounds fuzzy and blown (only a month in with that weak stereo!). These little Boss speakers are champs for the price. I wanted to wait a while for them to get broken in and have a wide range of music piped through them so I could give a better review. They handle classical, rock/metal (DragonForce), symphonic metal (Within Temptation), and dance (Cruxshadows) with ease and clarity on the 50 watt x4 stereo. I'm able to pick out details I wasn't catching before. They're not heavy on bass (obviously), but for $20, I don't think you'll find a better little speaker (heck, for multiples of that price). I did not expect the amount of clarity I got, and am blown away by getting it at this price! The fact they are 4 way makes a difference. Don't expect miracles, and you'll be pleasantly surprised. Keep in mind that I'm using a cheap under-powered stereo, so I'm not challenging these or throwing them as much as they could/should take, but at my max volume they're still loud (just not ear-bleeding loud) and clear and great for my commute. If you need great little speakers and aren't looking to spend a lot- these are them. ... show more

    • Good sound for high frequency.
I installed these on a 98 Chevy ext cab (3 door) for a welcome home present for my husband(he was gone for the military). The original speakers are located in the truck towards the top by the back window. Well those are 4x6. I cut a hole in the back door and on the other side in the same place.(Its only a door in one side) And i just clipped the wire and put new wire running under the carpet. I drilled a hole in the side of the door and ran the wire up through the door seal. I had to cut some metal too, not just the plastic panels. You have to have something to mount the speaker to. And put foam in between the speaker and metal or it might rattle. I used the same speaker for the front but in the 6.5 inch round. I also have the Boss Bass800 Amplified Sub and the Boss BV7320 Receiver. It sounds absolutely amazing for a low cost system. I wish I would have bought a better receiver as this one is hard to wire in and I still haven't figured out how to get the video to work. I also can't use the aux cables but I'm assuming its the same reason that the video won't work. I tried contacting customer service but I always get put on hold and I left a message a couple times but never heard anything back. That's why it only gets 4 stars. POOR CUSTOMER SERVICE. But, It is a very good product. The system has been in about 4 months and it still sounds good. The sub is broke in now. It gives just enough bass for a truck. The receiver has started making a weird noise when turning on coming from the CD player. Not sure why. ... show more

    • For the money, they hit!
Style: 5.25" 4-Way Pattern: Speakers
I have a 91 VDub Wolfsburg Jetta that I have been spicing up, reliving my youth. And last year I bought some 3.5 Rockville 3 ways. I didn't realize the Boss headunit(my father is a car dealer, he pulled it from a car and gave it me) I am using has a built in 300 watt Amp. The Rockville speakers were only 30 watts. I replaced them with these Boss speakers and also put in some 3.5 Boss Chaos, 140 watt. I hooked it all up with the Rockville 6x9s and wow what a difference! I am probably going to get some Boss 6x9s so I have it all Bossed out! I bought a 10 inch Rockville sub for the spare tire but I don't even think I'm going to hook it up. For the money, you can't go wrong with these speakers and the 3.25 Boss Chaos! I can't wait to drive my car to work tomorrow! Beastie Boys will rockin!!! ... show more

    • Not to be used by themselves
Style: 5.25" 4-Way Pattern: Speakers
I put these in a 2007 Mack Dumptruck. The fit was exact and the speakers themselves are very durable and built tough, but if your looking for LOUD....these are just what they say.... mids. They sound good as long as the song that's playing doesn't have alot of bass in it, because turned all the way up, bass will distort them. Other than that, well made and durable, but only good for low to mid level sound. ... show more
