JL Audio 8W7 Review

The JL Audio 8W7 is the 8-inch version of its’s W7 line. The W7 series is JL Audio’s most recent car subwoofer release and is known as the most technologically advanced out of any of the JL Audio products. The entire line features six new, patented technologies never before seen in the lineup, mostly because none of the previous products, remade in a second version or not, can even relate; JL Audio built the W7 series from scratch and not from a previous model. The W7 series focuses on sound quality and volume at the same time; that is, JL Audio wants to see how loud they can turn the party up without having to sacrifice the sound.

The 8-inch version has drawn numerous positive reviews from car audio experts and leading organizations. Car Sound and Performance calls it the “best damn 8-inch subwoofer ever made”. It’s small, yet powerful, and the 8-inch subwoofer has never been made so well in so long. It’s really no wonder that it’s getting rave reviews. JL Audio has certainly taken advantage of the situation and brought the little ones to own the bigger ones.

It is reported that this 8-inch version almost didn’t make it to the final lineup. The 21st century is thinking that bigger is definitely better, but that’s not the case here. The smallest version, a size rarely seen in the lines of other companies, has proven to be just as powerful as the other, more popular sizes. While the competition is racing to see how big it can make subwoofers without losing power and quality, They suddenly dropped a smaller size, which broke the stereotype that smaller subwoofers won’t do much good at all.

A feature that seems insignificant at first, the owner’s manual is actually quite important when it comes down to the actual installation and optimization of the JL Audio 8W7. Many consider it’s owner’s manual one of the best, because it not only includes the standard enclosure recommendations and specifications, but also includes recommended amplifiers to pair up with the 8W7 and tips to get the best out of the system through tweaking without busting it.

Overall, if you want to downsize from a 10-inch or 12-inch subwoofer, or want to try something different that’s hard to find on the market, the JL Audio 8W7 is a nice place to start. It takes everything people love about the 10 and 12 inch pieces, upgrades it, and repackages it as an 8 inch. Seriously, if you want something that’s even more powerful than many other subwoofers on the market, you’ll want to choose the W7 line. But if you want something that’s compact and does the same, you’ll want to choose the 8W7.

Choosing the Best Car Audio System

The basic components of a high-quality car stereo system are an AM/FM tuner, a CD player, an amplifier (optional but recommended) and great speakers.

Rule: No auto audio can equal the performance of fine home equipment. The car compartment is small, besieged with engine and traffic noises, and surrounded with competing electrical signals. And all of this in a moving environment. A welter of technical and personal choices dictate the final package.

General guidelines: Shop around. Car audio components are often discounted. Check mail-order houses and the Internet for the best buys.

Essential: Deal with reputable businesses and buy name brands. Make sure you can exchange or return components in case they prove incompatible or do not fit into the car. Remember each unit must be installed and may require custom mounting accessories. Keep personal tastes in mind. Rock and country music fans usually prefer stronger bass ranges. Classical music requires good mid and treble.

How to allocate your spending: 40% to 50% for tuner/tape player, 25% to 30% for amplifier, 25% to 30% for speakers (unlike home gear, for which half the recommended expenditure may go for speakers alone).

General recommendations: Components are a better deal than manufacturer-installed original sound equipment. Good manufacturer-installed gear can cost $1,000, a price that will usually bring you far better sound if spent on components. Try to find a dealer that has set up a sound room to hear and compare different systems.

New-car buyer strategy: Buyers planning to purchase components should insist on a delete-option clause, eliminating the installed radio cost.

In-dash versus under-dash components. Under-dash components are easily installed.

Overriding disadvantage: A thief can slip out the under-dash gear as easily as an ashtray. Choose in-dash tuner/CD players unless you want to stow the components in the trunk each time you leave the car. (If you still prefer an under-dash system, Sony components are top-notch ones.)

Amplifiers: Most auto-sound packages benefit from amplifiers that strengthen bass and high-treble tones.

Problems: Amplifiers are bulky and often must be installed under a seat or in the trunk. Unless your tuner has a bypass circuit permitting you to plug into the preamplifier, your costly amplifier will only boost the distorted output of the built-in amplifier.

Smart buying: Look for amplifiers measuring power in watts (w) per channel in terms of distortion (THD). Goal: About five watts per channel at 1 % distortion or less. To get this, the amplifier may require 50 watts per channel because few operate at better than 10% efficiency in a car.

Bi-amplifiers: They offer separate power boosts for bass and treble ranges. Bi-amplification may be called for when separate bass and treble speakers are installed.

Speakers: Speakers must be compatible with amplifiers. Their power capacity should be slightly higher than amplifier. Example: Get 60w speakers for a 50w /ch amplifier. One way to be sure of speaker/amplifier compatibility is to purchase them as a package.

Stereo sound requires at least two speakers. Many enthusiasts choose four. Non-directional bass speakers are best placed in the factory cutouts in the rear window shelf. Next best placement: In rear doors. Treble speakers can be mounted in front door panels or under dash.

Installation: Unless you are highly skilled electronics hobbyist, have the auto-sound system professionally installed. Allow $150 to $200 for installation, and get a satisfaction guaranteed agreement.
