    • Very good for price
Great condition, I was impressed with the mid bass from these speakers and the clear sound. Had a little button on the speaker helps get a sharper sound, nice surprise! All in all these speakers preform better than expected and for the price definitely worth it!!

    • Jam up!
I’ve been a sound connoisseur for almost 30 years. These are an excellent value. Match them with plenty of power from a small JBL amp and enjoy clear powerful full spectrum sound. I have zero complaints about these speakers. I’m going on year 3 with them right now. Also got the 6.5 for my back doors. The gto lineup is great. I’m comparing to Memphis, Kenwood, pioneer, kicker, & clarion. I would say they have a better range balance than kicker or kenwood with stronger bass. Pretty similar to pioneer silk dome Kevlar speakers but not quite as expensive. I like the low frequency output of the jbl better than the pioneer. Clarion has always produced some top line full range speakers. These jbl are as good as the best clarions I’ve heard. Don’t hesitate. You will like them. ... show more

    • Noticeable upgrade from stock 2016 4Runner front door speakers with OEM head unit.
I have a 2016 4Runner Trail edition with the standard Entune head unit (not the upgraded JBL system). I've already done the H631SFJ101 tweeter upgrade on the dash as recommended an a lot of 4runner and Tacoma forums but the low end was pretty muddy/sloppy sounding. SOUND COMPARED TO OEM SPEAKERS WITH ENTUNE HEAD UNIT I replaced the stock speakers with these and instantly noticed better clarity and tighter bass. The overall bass is slightly greater but definitely tighter. Speakers are also not fully broken in yet but it's a noticeable improvement from the start! IF you have a 5th gen 4Runner you'll also need the Metra 82-8146 speaker adapters (for front doors) and Metra 72-8104 speaker wire harness. ***If you're looking for a super audiophile experience then you'll probably need to get an amp and component speakers with a sub/s to achieve that.*** However, if you're just wanting to get noticeably better overall clarity and tighter bass out of your 5th gen 4Runner OEM Entune audio system then most people do the dash tweeters first and if that's not enough then you can drop something like these in and work your way to the rear doors if you want. INSTALLATION ON 5TH GEN 4RUNNER SUPER EASY! With the Metra 82-8146 speaker adapters (for front doors) and Metra 72-8104 speaker wire harness it took about 10 minutes per door including prepping speakers and using weather stripping to seal speaker to mount and mount to door. I plan on dropping in a pair of PowerBass OE652-TY 6.5"s for the rear doors and call it good. ... show more

    • Better than I originally thought.
Review Image by Ken
I bought the 6 x 9 GTO939's that I received today and mounted in 6 x 9 enclosures. So far I have tested them on my home stereo and they seem good. My bookshelf Bose speakers are smaller and sound better but to be fair I really shouldn't be judging a car speaker in the house. Hopefully when I get them in the car they will benefit from the different acoustics. Only a few things I didn't like. The grills have two fairly large openings in each that I suspect will allow the cone of the main speaker to become the final resting place for dead insects. You need a 3mm Allan key if you want to use the screws that come with to mount the speakers and the terminals where you connect the speaker wires are different sizes and connectors are not provided. Pretty light weight for 6 x 9's. Nothing like the old school JBL t545's I had in the late 80's but they sound pretty good under power. ... show more

    • Amazing!
This product was beyond what was expected! I highly recommend this speakers to anyone that wants to hear a good bass. I went with these because I own the portable JBL charge speakers and I love the quality sound. Let me tell you they do not disappoint! I bought my dad some infinity speakers same size and I was disappointed with the quality sound when it comes to music with heavy bass. Those sound a little distorted so I’m going to switch them out to these. I did however turned off the tweeter on these JBL and it was a much smoother sound. 3 way speakers do distort the sound quality when it comes to the high bass and super high tones. I did purchase the smaller jbl club speakers for my front dash to help with what a tweeter would do but it was not necessary! I like music with high bass such as Hip Hop, Electric House Music, EDM type of songs, and Alternative rock. Let me tell you these 2 speakers on my Dodge Ram rattle the mirror when the bass hits! If you like the club scene and quality music at a club setting I highly recommend! Just a quick tip before putting the door panels back on or the speaker screen try them with the tweeter on and off to your liking. Also buy the quick adapters for the speaker wires according to your car! Saves you from cutting wires and trying to tape them in awkward hand positions. ... show more

The quality is amazing, strong power sound and a decent volume range, performed great and has lasted me 2 years were still strong after half a year of sitting in broke down truck and would sound just as good as day I bought them, definitely recommend, my only issue was they stuck out to far and we're just barely to far out for door to fit so I had to trim the speaker plastic to make it fit but that's it, and it was worth it for the price of these ... show more
