Top 10 Ratings On Alfa Romeo

Customizable 9″ touchscreen We live in tablet times, and Alpine’s iLX-F259 multimedia receiver gives the people what they want – a 9″ touchscreen that “floats” over top other dash controls and fits in vehicles that previously couldn’t accommodate a comparable touchscreen receiver. Best of all, an oversized interface means you get big, intuitive controls and plenty of information at a glance, so it’s easier to keep your eyes on the road. Alpine has also made this receiver their most customizable, letting you drag-and-drop audio sources to create up to three home screens that you can swipe between. You can even personalize backgrounds with your own photos. This is your radio, your way, with all of Alpine’s trademark sonic capabilities and the very best smartphone integration. Works in most dashes The iLX-F259 comes in two main pieces: a 2″ tall chassis and a 9″ touchscreen. The chassis fits in most single-DIN dash openings, and since there’s no disc player, the mounting depth shouldn’t be an issue for most vehicles. Once you’ve mounted the chassis in your dash opening, you can choose from five available vertical mounting positions for the screen, giving you the flexibility to enjoy the radio without blocking essential dash climate controls. Your vents might be partially blocked, but Alpine designed the radio to function under typical in-vehicle temperatures. Adjust to your liking Once you’ve determined the best vertical position for the display, you also have the option of changing the screen viewing angle up to 45 degrees forward or 20 degrees backward. This allows you to accommodate for angled dashes or just to get a better look at your display, depending on its position in your dash. After you’ve chosen the best positions, four screws hold the display safely in place as you interact with it. All the options There’s no disc player in the iLX-F259, but it does include several ways to enjoy your media.

The new Constant Power amplifiers are some of the most powerful amplifiers on the market. The T1500-1bdCP is based on the legendary T1500-1bd amplifier design with a proprietary “Constant Power” configuration delivering up to 25% more power (Watts) across all impedance loads. The listening experience is cleaner, louder and more impressive than ever before. At 1,500 watts, this monster will run any demo vehicle competing in Sound Pressure Level.

Rockford Fosgate Power Series Amplifiers Power > Size. These compact amps deliver the same gut wrenching power as its big brother, but their chassis designs are up to 40% smaller. DTM (Dynamic Thermal Management) allows efficient heat transfer that minimizes physical size and enables installs under seats and other compact areas when abundant power is required.

CEA-2006
Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier’s output power ratings are REAL POWER numbers, not inflated marketing ratings.

Class bd
Rockford Fosgate bd topology is a revolutionary patented design, integrating a technology that is more efficient than typical class AB and has lower distortion than class D designs. POWER bd amplifiers are 75-80% efficient vs. 20-60% efficient class ab amplifiers. What does that mean? More power from your amplifier with less drain on your vehicles electrical and charging system.

Constant Power
Music and speakers have a dynamic relationship. As the frequency of music varies, so does the impedance of the speaker. This patent pending technology gives the amplifier the ability to instantaneously deliver its maximum output power to the speaker without regard to its varying impedance while still maintaining its high-efficiency and thermal performance.

Differential Inputs
Differential input circuitry measures the voltage of both the (+) and (-) input signal. The circuitry subtracts the voltage common to both conductors (noise) resulting in only the clean signal. This allows only clean signal to enter the amplifier.

DSM
DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

Dynamic Thermal Management
Heat is often inefficiently dissipated across a heatsink causing “hot spots”. Rockford Fosgate engineers have developed an award winning cooling design called DTM. This patent pending design seamlessly manages the output of power supply temperatures, while evenly distributing the excess heat across the entire amplifier.

MEHSA³
MEHSA³ (Maximum Efficiency Heat Sink Application–gen. 3) reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.

Punch EQ2
In the early 70’s, Jim Fosgate studied the acoustical properties of automobiles. Utilizing a real-time analyzer and pink noise, he would graph out the acoustical characteristics of each car he tested. Jim discovered three problems that were common to all cars: a midbass hump between 100-275Hz, a steep roll-off of high frequencies from 2kHz up to 20kHz, and reduced bass response below 50Hz.

The Punch EQ on-board equalization circuit helps correct for these acoustical deficiencies in the listening environment. When set to Low-Pass(LP) operation, it becomes a variable Bass Boost. When set to High-Pass (HP) operation, it acts as a variable Mid-Bass and Treble Boost. When set to All Pass (AP) operation, both Bass and Treble frequencies are boosted.

Rockford Fosgate Avatar
These Avatars are a personal signature from the Rockford Fosgate team member who designed and engineered this fanatic product. This statement illustrates Rockford’s commitment to being Designed and Engineered in the U.S.A.

TO-247 MOSFETs
Rockford Fosgate amps use custom TO-247 MOSFETs. These have 60% more metal tab area for more power capacity, lower impedance and improved heat dissipation over traditional TO-220 MOSFETs found in competitor amps.

Strong Sound – Powerful Style

The jet-black design leaves a clean finish on the fortified aluminum heat-sink. The stream-lined and high-tech appearance will definitely add some muscle to your audio.

Total Audio Control

Once you’re connected, customize and adjust your listening experience to your liking with the amplifier’s control center. You can personalize and fine-tune settings like:

• Level (Gain) Control – These are basically volume controls. This will allow you to adjust the incoming signal to the amplifier so that it works well with your headunit or to match the level of other amplifiers in your system.
• Phase – Allows you to change the relative time that the waveform meets your ear. With standard subwoofer installations where the subwoofer is behind you, the phase should generally be at O. When subwoofers or woofers are in the kick panels or door panels, an adjustment is useful in delaying the timing of the wave meeting your ear.
• High-Pass Filter – The High Pass crossover is used for sending midrange and high frequency information to a particular speaker. Activate the High Pass crossover if you intend to drive satellite or coaxial speakers in the system along with subwoofers driven by the amplifier’s channels. Even if your system does not include subwoofers, it may be helpful to activate the High Pass with smaller speakers to protect them from low frequency information to achieve better sound.
• Low-Pass Filter – Filters high frequencies out of the music and improves efficiency and sound quality by allowing only the low frequencies to pass to the subwoofer. Sends only low frequency information to particular speakers. Low Pass crossover activation is usually desired if you intend to power subwoofers.
• Bass EQ – Variable from a range of decibel adjustments, this feature regulates the impact of your bass kick. You’ll have manual control over balancing and correcting the frequency range of a given sound.
• Crossover Switch – Basically acts as a filter and limits selected frequencies going to a subwoofer, which gradually reduce frequency signal strength. Routes output of the Low Pass or the output of the High Pass filters, or ‘Full’ to the power amplifier.

*Please refer to table below for amplifier specific information and adjustment options.

Speaker Output Connections

Connect right and left speaker wire to corresponding speaker output terminals. Be sure to correctly connect the selected speaker wires to their respected speaker terminal, this includes both positive and negative wiring. Improper installation/wiring will result in the speaker cones to move out of phase which can cause bass cancellation.

Input Connections

These amplifiers have inputs for Low Level input connections. The Low Level signal is carried through RCA connection cables.
