3rd Demo - Dual W8Q-1071F Tapped Horn

One more excursion video of the dual Tang Band 8x12" 16Hz tapped horn. After discovering a loose screw on one of the drivers in the last video, I decided to re-test using Flight of the Phoenix at reference levels to see what changed now that the air leak at the front driver is gone. This is the result. Power provided by a bridged QSC RMX-1850HD (about 1100W), highpassed at 10Hz. Note that the SPL meter is set on its highest setting, recording peaks in excess of 126dB. This amounts to about 122dB peaks at my listening position. The distortion you hear is massive amounts of low frequency energy overwhelming the camera's microphone. This thing was literally vibrating the concrete floor around the horn mouth.

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.

Hummer H2 Interior and Audio Install

2006 Hummer H2

For this project we upgraded a 2006 Hummer H2, stock interior to a full custom leather interior, and installed a custom JL Audio sound system. Lets go over some of the install...

First we started with removing the interior. Main reason why we start with the interior is, this takes some time, we prefer to get a head start on this part of our project. It also helps at the end of the project, so we are not waiting on parts. Once the seats are out, we proceeded with stripping the old leather wraps to get to the seat heaters. At the same time we started making a template for the new leather. This interior we used high quality black leather for the seats and audio rack. We also went with a white stitching and custom embroidery on all the headrests and on the audio rack. Along the way we added LED interior lights for mood under the seats and in the amp rack. The finished interior consisted of the following: new leather seats, LED interior lighting, LED mood lighting under seats and on amp rack, Kenwood DNX 9960 headunit, 2 6" head rest monitors, one 10" monitor on amp rack, bass control on dash, and along with push to talk GPS. Each door received a JL Evolution C5 component speaker, and our tweeters were placed on the door pillars

Now that the interior has been removed we move to the custom audio box. Lets go over how we want our sub box and amp racks. The best place to start is with the subs, we are using 2 JL Audio 12"W7 subs enclosed in a sealed box, which needs 1.375 cubic feet per sub. The customer with this vehicle wanted more "punch" or "kick" to the bass, thus the sealed box. In this application we used 1.25" countertop MDF for the top and.75" MDF for the rest of the box. Once you have built your sub enclosure to the right dimensions, you can see what room you have left over for other equipment. After your sub box is in place you can start the amp rack mock up. Figure out how you want them to sit and look, then build a secure mounting platform. You should be extremely careful with the mounting of the sub bow and amp rack. If they are not secured properly they can cause serious injury if they come loose in a sudden stop or an accident. We always bolt our sub enclosures to the car to ensure safety. This is also a good time to add Dynomat or any other sound dampening materials needed. Now that you have built your sub box and amp display its time to pull and start wiring.

For this install we used 16 gauge wire for drivers, 18 gauge for tweeters, and 14 gauge from crossover to amplifier. Next is the Stinger 6 channel audio RCA's and 2 video cables. Powering the system we ran 0 gauge Stinger power wire and 4 gauge for the ground which will goes straight to the chassis at the amp rack. Finally we added a 250 amp inline fuse close to our Stinger audio battery.(Remember always place your fuse as close to the battery as possible in case your power line shorts out).

Now that we have a majority of our wire run we installed a Viper auto start and alarm. If you have never done this type on install it is recommended that you have done professionally. Please remember most cars will require additional electronic units for coded keys as well as radio replacement. Never assume you just can install a radio and be done. When it is not done properly it can cause many problems. Our H2 needed 5 devices installed so that the auto start and steering wheel controls would function correctly, as well as the Sirius radio and onboard CPU. Now that we are done with wiring and everything is hooked up, we run a complete test before reassembly. This is the time to program any extra devices that were installed. Once all devices are running properly, turn off the vehicle and restart it to complete set up.

Now that we have tested the system we can start putting the new leathers on the seats and reinstalling them in the car. After its all back together we can setup or tweak the system to its full capability, again remember this should be done professionally.
