If you are looking to power up a 10CVR102, 10CVR122, or a 10CVR152 subwoofer to a final impedance of 1 ohm, then look no further than Cerwin-Vega’s STEALTh500.1 monoblock amplifier. This amplifier offers a power rating of 500W RMS @ 1 ohm giving you all the power you will need. The use of a Thermal Management System, monitors internal thermal output by reducing power output when the amplifier begins to overheat. This allows the amplifier to have a continuous performance giving you uninterrupted bass reproduction. Apart from being very small Stealth amplifiers feature a full range Class D chip set that improves efficient and performance and increases reliability. It also reduces noise and filters out other sonic disturbances.

There really is nothing better than a JL Audio amp, this amp will be extremely efficient and features technologies like Advanced Thermal Rollback in order to eliminated thermal shut-down events. The amp features low and high pass filters as well as noise killing differential-balanced inputs for clean and reliable power output.

Alpine MRX-M50


The Alpine MRX-M50 is rated at 500W RMS @ 2 ohms, making it the perfect amplifier when wanting to run a 10W3v3-2, 12W3v3-2, or a 13W3v3-2 subwoofer. Its small design and both high-level and low-level inputs allow this amp to be installed in virtually any vehicle, not many other amplifiers can offer that. The amplifier also features a variable bass boost along with a low-pass filer and subsonic filter that will allow you to manipulate the frequencies to your personal taste. When purchasing an efficient sub like the W3v3 you need an amplifier that is just as reliable and also affordable.

Boston Acoustics GTA-100m


Boston Acoustic’s GTA-1000m monoblock amplifier is rated at 600W RMS @ 4 ohms. This amp will allow you to run a 10W3v3-4, 12W3v3-4, or 13W3v3-4 subwoofer to a final super efficient impedance of 4 ohms. This is going to give you the best performance, the amplifier won’t have to work as hard and draw less power for lower thermal output. The woofer will run more efficiently as well due to the constant supply of undisturbed power. The GTA-1000m features balanced asymmetrical inputs for noise cancellation and fully adjustable and selectable low and high-pass crossovers for complete customization of sound reproduction.


Alpine’s 2011 X-Power Small Chassis Series Car Amplifiers

Alpine MRX-M1000

Alpine is well known for providing top quality products in multiple categories within the car audio spectrum. When you think of Alpine the words reliable, quality, and affordable come to mind, these are the principle foundations on which their new 2011 X-Power series amplifiers have been built upon. The X-Power series amplifiers are available in 4-channel, 5-channel and monoblock configurations, making them perfect for any application. Alpine has designed these amplifiers with every consumer in mind by providing a small chassis design that makes them versatile and mountable in any vehicle. Alpine’s use of trickle-down technology has provided this new series of car amplifiers with some of the qualities found in higher-end models , giving you the best dollar- per -wattage performance of any car amplifier in this category.

Alpine’s X-Power amplifiers feature a Dual Feedback Modulation Loop that provides the cleanest and best possible distortion free power output. This is done by a real-time-error correcting circuitry that analysis the signal twice, both input and output signals, throughout the entire process of the application. This ensures that you are getting the best possible performance from the amplifier at all frequency ranges. The use of a Multi-Stage Power Management circuit protects the amplifiers from excessive heat that if left unattended will damage your amplifier and lower the quality of your signal and thus the quality of your music. This is done by a constant monitoring of component temperatures throughout the amplifiers, which then decreases the power output if the components reach an unsafe temperature. The circuitry works in two stages each lowering the power output as needed to keep the amplifier from shutting down thus providing uninterrupted performance during long listening sessions. Apart from the technologies found in these amplifiers, is the versatility of these amplifiers. The small chassis design makes them easy to mount underneath the seat of the driver or passenger. This cuts down the length of wire that is used and reduces the possibility of interference that is usually found in long wire lead installations. The 4-channel high input speaker level connection allows the amplifiers to be installed into any factory installed system without the need of RCA connections, making the accessible to anyone no matter what type of vehicle you drive. Monoblock models, like the MRX-M100, feature a preamp output that will allow the daisy chaining of multiple amps without the need of an adapter, this is a great feature if you are looking to add more power to your car audio system and want to keep the same series of amplifiers throughout your installation. Every X-Power amplifier will come with a proven and tested Birth Power Certificate that guarantees its actual power output, giving you every single wattage of power that you pay for an even more since these amplifiers are underrated. With the ability to add a remote control bass knob on some these models, Alpine’s X-Power Series Car Amplifiers offer high performance, dependability, quality and affordability, making them a great addition to long line of Alpine Car Amplifiers and even an better addition to any car audio system.
