Infinity REF-9633IX Reference 6x9 Inch Three Way Car Audio Speakers

So I have a 2015 outback that has literally ZERO options. Now - still it has some stuff that comes standard like it's Starlink LCD screen headunit, backup camera, power options, etc but most Outbacks you find will at least have the primary "premium" audio - the Harmon Kardon speakers which included 4x6 in front dash, a center speaker in the dash, two door speakers and 2 rear door speakers.Mine has none in the dash, none in the center speaker space, and super cheap (also super light, like under a half pound) speakers in the front and rear doors. Bass was almost non-existent until you turned it up and you could get a little bit but it quickly turned into static/distortion.I ONLY put these speakers in the front doors and the whole car is filled with clear sound and very rich/thumpy bass. No it won't replace full subs if you're a big car audio person, I just like to be able to enjoy my music and hear it with the elements it was meant to have. Now I have front 4x6's and rear 6 1/2's to go in but I could truly be happy with just these in the front doors but at this point and how happy I am replacing the factory fronts - I figured I might as well go all the way and probably get even more blown away.Super happy with these and they were well worth the money!

Infinity are my go-to for car audio door or deck speakers. Without fail, I've always felt I got my money's worth with Infinity speakers and these are no exception.Brilliant, crisp, clear sound with solid, hard hitting bass and a nice, flat response curve.Very low distortion if you feed them with a solid amp.Note to those replacing stock systems:Most distortion or lack of bass can be traced to amplifier issues. Hit em with a serious amp and they'll perform beautifully.I'm running a 600w x 4 RMS dedicated amp for these in the back deck and 6.5s in the doors. Overhead in the amp translates to sound quality. Underdriving speakers results in shorter speaker and amp life as well as crap sound quality. Stock amps are impedence and perhaps even frequency tuned to stock speakers. Change 1 and sound quality is first to suffer.I like it LOUD, but not at the expense of thousands of dollars, distortion or a funky response curve that require special eq setups.Don't forget, break them in, like most good speakers. 1/2 volume or less for the first hour or so is a good rule. Also, don't crank up the stereo before the car is warm. That's when the foam surround on the woofer tears from cold stiffness. And besides, sound quality suffers at low temps with all speakers.

I was amazed when I took out the factory speakers on how cheap, lightweight, and crappy the stock ones were. Just holding the speakers you can tell the difference. They will sit deeper into the speaker box than factory and will hit the window track, this is easily fixed with a 1/4 inch 6x9 spacer found on amazon. The extra 1/4 inch will not interfere with door card. The sound is night and day. I have the cheapest radio found in a ram truck and these make the radio sound pretty good. I replaced the dash speakers with 3.5 infinity speakers and the front and rear doors with these. I was planning on slowly adding new components over time but this might just be enough for me. I dont use a 10th of the features on expensive radios, just want a better experience with the sound. I may add an amp and sub later, I doubt it, its just an all around good improvement so far.

Infinity Reference 9633IX 6"x9, much needed improvement over stock. Sound quality is everything I expected, crystal clear highs and decent mid to low, I have a sub box, so I bought these to keep up with the bass, without an amp in my 2020 dodge charger!

Changed the stock speakers in my 2020 Ram with standard six speaker setup and immediate Noticed the crisp/clear highs and mid range. Bass was still not enough but it definitely needs an amp to get full quality I know they are capable of. Great value and great quality. I will purchase again in future

These fit just fine in the rear doors of my crew cab 2018 RAM 1500. If you have the stock Alpine 9 speaker system, the rear doors receive the full range signal so getting 3-ways instead of 2-ways "should" be better. However I did not compare them directly with 2-way speakers.Compared to the stock system, these speakers are clearer with a crisper bass response.Pair them with the Metra 72-6514 harness for trouble free installation.

Excellent value with powerful bass sound from a Toyota stock stereo. This was definitely a tremendous upgrade from the stock speakers. Bear in mind these speakers cost $149 with Crutchfield. Even though they throw in the brackets and sharness Amazon's price was still the better price. I paired them with Kenwood Excelon KFC-X2C 2-3/4" Custom Fit Mid-range Speaker in the dash. This is the perfect combo for our 2015 Prius V.

speakers sound amazing with our without an amp. Plenty of bass. Mids and highs. Sound is crisp and clear. If you're going to put them in the rear deck leave the +3db button pressed down. Makes them come alive even though there in the back. I definitely would recommend them to anyone who wants a well rounded sounding speaker that doesn't cost a fortune. Tip if you want more bass install a strip of foam tape under the speaker and deck surface to seal it off
