Sure, the better you are at critical listening, the more accurate a speaker you will choose, but when it comes right down to it, pick the one that sounds best to you. The JBL GTO629 speakers are a fantastic choice for car audio enthusiasts seeking high-quality sound reproduction, impressive bass response, and versatile installation options to elevate their in-car listening experience. For a 6 1/2" speaker they have a nice mid bass and excelent highs (I set the button on the Tweeter to flat). As a result, the low-frequency response is improved, and it takes less effort to generate those crucial musical notes that larger speaker sizes are frequently associated with. To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit.

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. The other half of that where they say you'll get more output is where it comes together and makes sense.I bet your car has a factory amp in it because most cars without amps are usually run on a 4 ohm load and cars withfactory amps lime bose, Infinity,Harmon kardon,etc. On Count Basie's “Take the A Train,” the Bosendorfer grand piano sounds open and natural without much unwanted coloration. One carbon-injected cones in the GTO 629 provide larger overall speaker-cone area than other cones in its class. The GTO 629’s Plus One carbon-injected cones provide more overall speaker-cone area than other cones in its class.

The 3-ohm impedance design ensures compatibility with many car amplifiers, maximizing efficiency and output. Sometimes speakers that are this “forward” in the mid-range can fatigue in a short amount of time, but that isn't the case here. UniPivot is an innovative feature on the GTO 629 that allows the tweeter to be aimed at the listening location for better stereo imaging and high-frequency response at the listener’s ear. JBL® GTO 629 6-1/2-inch (165-millimeter) speakers handle a robust 180 watts peak power (60 watts RMS).The sonic performance of various individual loudspeakers can be very different and a very personal preference. This much power makes for an ideal match to systems powered with head-unit or factory-amplifier power levels. In automobiles, coaxial speakers are two- or three-way loudspeakers with the tweeter, or the tweeter and a mid-range driver, mounted in front of the woofer, partially obscuring it. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers. If you are a long time veteran, feel free to use this as a form to discuss with other like minded enthusiasts.

If you prefer to surface mount the speakers on the top of your door, you'll be happy to know a very nice set of grilles is included along with all the required mounting hardware. My supposition is that they believe that the amount of extra push they're putting into your amp is negligible relative to the amps ability to handle the extra workload. The wide frequency responses that these speakers provide will leave your ears very satisfied when you're listening to your favorite songs. The three ohm voice coils allow the speaker to operate at an efficient 4 ohms once they are being powered, allowing them to utilize every watt of power your head-unit or 4ohm stable amplifier can produce.What's not covered : Misuse, abuse, defacement, physical damage of any kind, and improper installation / operation. A wide frequency response that extends beyond 20kHz helps to compensate for speaker-placement variations in your car and for human hearing deficiencies in the high-frequency spectrum above 15kHz. These speakers feature a vented magnet with a high thermal-capable voice coil which effectively dissipates heat, ensuring the longevity of your investment. JBL builds in a UniPivot™ design that allows you to aim the tweeter's sound more directly at your ears, giving you a more detailed soundstage.
