CEA-2006 Compliant – Amplifiers

By Gideon V. – Sonic Electronix Editor

Have you ever read the line that says “CEA-2006 compliant” on an amplifier’s features and thought to yourself, “I wonder what that means..”? CEA-2006 compliant is not just an advertising claim. If an amplifier is CEA-2006 compliant, that means that this amp has been tested by the Consumer Electronics Association to verify its ratings. By meeting the CEA 2006 standards, you can trust that the amplifier’s ratings are accurate. CEA 2006 tests the two most important amplifier ratings (and the two ratings that are the most likely to be fabricated): RMS Power (how loud it plays) and Signal-to-Noise ratio (how clearly it sounds). Both car amplifiers and car stereos undergo CEA 2006 testing in order to verify their external amp power rating. The CEA logo will appear on the boxes of products that meet the standards.

Are manufacturers required to submit their products to the CEA-2006 testing? Unfortunately, the answer is no. CEA-2006 testing is voluntary, so not all manufacturers send their products in for testing. Some manufacturers may overstate an amplifier’s power ratings to make it seem more powerful, and as a result, appear more valuable. This is why CEA-2006 testing is so important. In order to avoid buying amps with inflated power numbers, you should only believe the ratings of CEA tested products.

In order to make the testing uniform, CEA uses a standard that measures an amplifier’s RMS power and signal-to-noise ratio. This allows consumers to compare amplifiers across the industry. The consistency of the testing guarantees that all car amplifiers are measured equally, and most importantly, that they have accurate ratings. The CEA logo is officially licensed by the Consumer Electronics Association to guarantee that the product ratings comply with the CEA 2006 standard. Besides a CEA logo, CEA tested products mention CEA compliancy in the manual and on the manufacturer website. Avoid false marketing schemes and buy CEA tested products.

Boss CW Amplifiers

Boss CW Amplifiers

By Gideon V. – Sonic Electronix Editor

Looking for more bass for your buck? Check out the Boss CW line of car amplifiers. These Chaos Series Boss amps are reliable sources of power for car audio systems. Featuring built-in MOSFET power supplies, these CW amps will not let you down. From top to the bottom, these amps are built to last. CW amps feature a heavy duty heatsink for optimal heat dissipation. They also use a special 2-way circuitry that provides thermal and speaker protection. This special feature helps guard against blown amps and speakers.

The Boss CW150 2-channel car amplifier measures at 200 watts when wired at 2 ohms. This compact amp packs a lot of power for its size, and the bass boost function allows you to select just the right amount of bass. In terms of wiring options, the CW150 is configured with high level inputs, which makes it easy to connect it to stereos without RCA outputs. For stereos with RCA outputs, this amp also features nickel-plated RCA level inputs. which make for an easy and secure connection.

If you are looking for a four-channel car amplifier, the Boss CW350 is a 400 watt amp that features all of the great Chaos series features mentioned above. Its slight size does not affect its ability to produce power, as this amp can sufficiently power up to four speakers simultaneously. It is fully operational at both 4 and 2 channels. That means that you can wire the CW350 to only two speakers if you so choose.

Now let’s discuss the top models in the Chaos line. The Boss CW750 2-channel car amplifier is one of the best amps that Boss has to offer. This amplifier is rated at 440 watts of continuous power, and when bridged at 4 ohms, its max power rating is a whopping 1600 watts! How can it provide so much power? It uses a MOSFET Pulse Width Modulated (PWM) power supply. How does it do it? While an average motor powers on only half of the time, the Pulse Width Modulated power supply rapidly switches the motor on and off so that the amp is virtually always on, which makes for a much larger current. This maximizes the total power generated by this amplifier

The Boss CW950 2-channel amplifier also features a MOSFET Pulse Width Modulated power supply, which is one of the reasons why it can provide 2000 watts when bridged at 4 ohms. Like the CW750, the CW950 also includes a wired remote bass level control, which makes it easy for users to adjust the sound. Of course given all of the power that these amps provide, if you are fond of your ear drums, you won’t even want to push the bass boost all the way to maximum.
