    • Great speakers, but pay attention to wire polarity!
Got those speakers for my 2012 Ford Focus SEL 5 door, because I really liked components JBL GTO608C 6.5-Inch 2-Way Component System that I installed in the front doors. I use a stock head unit - non-Sony with Sync, driving 6 speakers. Overall, installation in the rear doors was very easy, as I used the OEM speaker baffles. High sensitivity of the speakers is evident - I can hear increased sound level at the same volume settings. So far the speakers seems like a nice addition to their "cousins" in the front doors - they (GTO628) add low and mid frequencies nicely to the overall sound. Highs from GTP628 are not as evident because there is no line of sight to the rear door mounting location when I am in the driver seat. But I noticed one very important discrepancy in the speaker installation instruction - its picture for the wire polarity swaps "+" and "-" wires. It is very important, as swapping them may lead to drastic decrease in the low frequency response from all speakers as perceived by the car occupants (see below why this is). May be this explains why some people report something like "no bass response from the speakers" after they replaced their car OEM speakers, all because they followed the installation instruction wire polarity. The installation instruction (you can get it from the JBL website when you search for GTO628 product page there) shows a particular "+" and "-" wire connection to the speaker. It seems that it draws the speaker from the magnet side. I believe that the correct wire connection would be when the same picture draws the speaker from the front (membrane) side. Here is my evidence: 1. When I examine the speaker tabs, the small white board (where all wires solder to) has a "+" sign engraved on it, and it does not coincide with the instruction-suggested location; 2. I used a 1.5V battery to test the speaker polarity - the speaker membrane should move up if the battery "+" terminal touches the "+" lead of the speaker. Result - the speaker "+" engraving pointed to the correct positive terminal. 3. GTO608 woofers have a particular "+" and "-" tab arrangement (you can get GTO608 instruction from JBL website) that agrees with the GTO628 engraving, but contradicts to the GTO628 installation instruction picture. Some basics behind speaker polarity: if even one woofer speaker in a car is connected backwards, its membrane moves in the opposite direction than those of the rest of the speakers. At low frequencies, this leads to "canceling out" the sound wave as, for example, it tries to "pull" the sound wave at the same time as the other speakers try to "push" it. I am very puzzled as to why manufacturer made such an error, and hope that JBL reps browse our reviews so they can correct the instruction. Otherwise more and more people will complain about "lack of bass response" in their review - all because of the incorrect speaker connection. Edit on 05/28/13 - forgot to mention - remember to remove sticky transparent film from the magnet back - otherwise when the speaker is exposed to hot summer temperature, the film will curl up and fall inside the door, potentially blocking one of the door drain holes. Edit on 05/29/13 - I agree with a reviewer who noticed decreased low-frequency response after replacing the stock speakers. I just got a rental Camry and was amazed by the car stock audio system bass intensity, even at moderate EQ bass settings. My body has shaken. Especially when this bass comes from a small speaker with paper cone and a tiny magnet (I could see 2 of them from inside the trunk). It seems to me that stock speaker designers tune the speaker impedance to the factory head unit (more on the speaker impedance is below). This would lead to very powerful bass, but makes mid-frequency response quite distorted. In general, speakers with smaller magnets (like stock speakers) may have a better low-frequency response (reason for this is quite complex). Each speaker has a very complex effective impedance curve, usually it peaks at low frequency (around 80-100 Hertz it can be as high as 20-100 Ohm for a large-magnet speaker with a 4 Ohm nominal impedance). This relates to the speaker membrane and driver design. Modern solid-state amplifiers present a 0 Ohm load to the speaker, meaning that speaker no longer can freely move around this peak, or resonant, frequency. This is so called "damping effect of a solid-state amplifier". Speakers with smaller magnets generally less prone to the damping effect at the peak frequency, so they can be moved by amplifier much easier in the usable bass range(50-80Hz). This is an oversimplified explanation of course. So GTO628 speakers may easily feel greater damping effect at low frequency than the stock speakers do. Result - decreased bass response (it is still there, it is just attenuated). Solution - to use an external amplifier that can deliver proper (higher) gain at low frequency (some amplifiers allow boosting curve right at the speaker resonant frequency). Or to use a dedicated subwoofer. I personally like neither of the options, so I just enjoy very clear mid-highs (with some hints of bass) from the GTO speakers driven by the factory head unit. ... show more

    • Good Bang for the Buck for my Acura TSX 1st Gen
I didn't give it 5 stars because there is some music I have that is poorly mixed and these accentuate the sibilance vs other speakers I have in other cars. But for well-mixed music, these are way better than stock, and awesome for the price range. Look into getting the fitted wires for your car, and also 1/2 rings if recommended since most cars today make installing speakers impossible. I put these in my 2006 Acura TSX and they did great, but the install took almost 4.5 hours because when you blow the door light apparently that breaker keeps the stupid radio from working which also has a separate fuse for the power amp. That took an hour to trouble shoot. You spend about 1 hour figuring out how not to destroy your door and how to mount the speaker (you need to use self tapping screws, put on the mounting ring, then mount the metal adaptor, then the speaker. Do NOT forget to put padding between ALL these pieces if you don't want to hear vibrating rattles when driving. Once installed, huge difference in way better clarity! So: 1) Speakers 2) Sticky tape foam for insulating against rattles 3) 1/2 Ring Adapters (or exact ones for your type of car) 4) wire adaptors (you need a small screw driver to "open" the metal prongs to fit your speaker, they come crimped too tight) 5) Make sure your car has extra fuses in case you blow something, many wires to the door are always HOT for door lights and power windows for so-many seconds. 6) Self-Tapping screws for the adaptor and smaller screws for putting this speakers metal plate to the adaptor ring. The adaptor ring is to bring the speaker out further. Many are used to prevent the speaker from hitting the window. This isn't a problem on the TSX. The problem here is the hole is too small for this speaker to insert all the way. You'll need personally: 1) Drill (recommend battery driven) 2) Philips screwdriver 3) small regular screwdriver 4) A set of drill bits for screws or self tapping screws. Likely 2 sizes, one for the 1/2" ring adaptor and one for the little metal plate here. It does come with it's own screws but they are kinda shallow. I like a little more depth for all the pot holes! 5) A plastic scraper to get the door pried open without damage. 6) String to tie your pried open door up, unless you take off ALL the electrical wires which may be a pain 7) small box to rest pried door compartment against out of the way of you speaker install. Probably more stuff, but if this scares you, get a friend or pro to do it, haha. Best of luck. ... show more
