Great Tweets

Written By csonnenb, Saint Louis, MO on Sunday, February 22, 2015

Crutchfield Customer Review (What's this?)

These are a couple of great tweeters. They are connected to the factory amp that came with my Chevy Equinox and they sound really good.

Crutchfield Customer Review (What's this?)

Pretty horrible. Got these to replace the tweeters in my dash and they hardly make any sound at all. With the volume up they just buzz and can't distinguish any sounds. Better off without them. Maybe they sound better in a component system but I doubt it.

Pros: None!

Cons: Everything about them.

Great tweeters!

Written By Ben B, Michigan on Sunday, September 14, 2014

Crutchfield Customer Review (What's this?)

I wired these into the stock tweeter locations in my dashboard and they vastly improve my stock stereo! I was thinking about redoing the whole system, but with the tweeters I might just live with the stock setup for a while. Vocals sound crisp and in front of me instead of underneath, cymbals and high pitches sound a lot more focused and clear. Best $50 you'll ever spend on your car stereo.

Excellent product. Very pleased.

Crutchfield Customer Review (What's this?)

I bought these tweeters for a stock replacement of the dash tweeters in my 2014 Xterra. It wasn't an exact match, so I had to fabricate a bracket. Very simple. They are currently running off stock watts and sound great. They add the perfect highs I was looking for. I recommend these speakers to anyone.

Pros: Excellent sound Easy install Durable

Good, clean sound

Great tweeter upgrade. I can't believe that I didn't upgrade to these sooner. Very crisp and clear.

Pros: Great Sound. Easy install.

Cons: Had to do some mod work. Cut away all the plastic that held the old tweeters and then Epoxy these in their place.

Jeep Tweeters

Crutchfield Customer Review (What's this?)

2007-2013 Jeep Wranglers have tweeters mounted in small "tombstone" mounts on top of the dash. Mine were stolen for some reason so I bought replacement mounts and then decided to try an upgraded tweeter. I had to cut away the inside of the mounts to install these larger tweeters but it was easy and it looks great! Oh and they sound great too!!

Pros: Good price and good sound

Cons: None

Installation was ok but had to do a custom installation had to splice wires for a '03 Vibe GT. Now I hear engine whine through tweeters. Wish I had a custom harness for tweeter.

Pros: Easy installation

Rockford Prime R165X3 6.5" 3-Way Speaker

Written By Ahmed, Chicago, IL on Thursday, April 18, 2013

These speakers sound sooo great very clear with bass. I had to replace my stock rear deck speakers and they sound soo loud and good. My stock speakers I had to crank the volume to 25 now i crank them to 5-9. My next step is to purchase the same ones for the front doors. The setup is so easy its a plug n play which crutchfield adds the wiring harness automaticly to your cart.

Pros: Easy plug n play with the free wire harness that comes with the speakers free. Price is great for those speakers.

Exactly as I expected

Crutchfield Customer Review (What's this?)

I am by no means one of those hardcore audio enthusiasts. I didn't want not expect the most amazing quality, merely to fill in some "dead space". This product was received quickly and was well packaged. The tweeters came with multiple mounting options along with clear and concise instructions for installation. They perform well hitting good highs and distort very little if at all.

If your looking to increase clarity and/or fill dead space these are a great option.

Pros: Attractive price. Low key design blends well with interior. Multiple mounting options. Clear instructions for installation.

Cons: None noted.

Great for the money

Always been a rockford and Crutchfield fan and i hate to write a negative review . But Im very dissapointed i mounted these tweeters in the door of my 2002 chevy and They sounded AMAZING!!! Very clear and very loud. But i am yet to figure out why they only lasted me 3 days. And yes they are running through their own crossover off a kenwood HU????

Pros: Great clear sound

Cons: Rockford Fosgate failed with the Prime series

Written By Matt C, Nokomis, IL on Tuesday, June 21, 2011

great purchase. if youre looking for tweeters that put out great crisp, clean highs, these are the ones for you! i mounted mine right into my dash and pointed them at my drivers seat, and man does my music sound better. i listen to alot of bassy rap, but the highs are much clearer now that i bought these. HIGHLY recommended

These are KILLER!

Written By Tom, Chicago, IL on Wednesday, June 15, 2011

Crutchfield Customer Review (What's this?)

Bought a pair of these a few weeks ago and just got around to dropping them in my door panels this afternoon. Pretty straightforward installation once I had the door panels removed and cut the holes out. I mounted these in the front doors of my 1994 Ford Ranger XLT and connected them directed to a front pair of RF 6x8 Prime speakers in the doors and the improvement in overall sound was immediate. The sound stage expanded tremendously, the upper end became much cleaner, crisper and detailed, and that brought a grin from ear to ear. My system is really pretty modest, I have an Alpine AM/FM CD Receiver and a 2nd pair of 6x8's in the rear along with a Powered Sub and a couple of smaller amplifiers and together it ROCKS enough for a 50 year old that wants to recall the days of his youth without attracting a lot of unwanted attention.

I have no idea what tweeters these replaced (newly purchased used truck), one
tweeter was dead. But, after changing the tweeters out for the pair of Rockford
Fosgate Prime R1T-S I can't believe the difference. Just changing the blown one
out I could hear the difference in sound between the two different tweeters. After
replacing both tweeters and testing the R1T-S, these give crisp, clear and much
brighter highs. They were easy to install and are a bargain at these prices!
Brought my sound system up to a whole new level.
