About the Rockford Fosgate T1500-1bdCP

Powerful bass performance

Power Series amplifiers actively monitor their speakers' performance using Rockford Fosgate's Constant Power technology. A speaker's impedance naturally fluctuates as it performs. So, just like your cruise control increases the engine's RPM to maintain your car's speed uphill, Constant Power maintains this amp's output by increasing its internal voltage and current when the speaker's impedance rises. This results in up to a 25% increase in the amp's total power output, especially in the crucial range below 50 Hz where a sub amp really has to shine.

Rugged construction, massive bass

Rockford Fosgate builds each Power Series mono amplifier with heavy-duty, state-of-the-art components. The award-winning Dynamic Thermal Management design manages the temperature of the internal components, distributing heat evenly for higher efficiency and lower distortion. The unique heat sink allows the heat to escape more readily so the high-power output transistors stay cooler and last longer.

Can you say 1,500 watts?

The T1500-1bdCP mono sub amp uses an efficient Class bd design to deliver up to 1,500 watts to your subwoofer system from a remarkably compact chassis. This amp can even drive a 1-ohm load, so you can get massive bass out of a wide variety of system designs. The variable 24/dB per octave crossover creates a more natural sounding transition from your speakers to your subs. And the 2-year warranty tells you that Rockford Fosgate stands behind this bass behemoth.

Features

Overview: With its super efficient Class-BD circuit topology and Constant Power configuration, the Rockford Fosgate Power T1500-1bdCP assures maximum power output. Due to its dedicated low frequency response, this amplifier is optimized for mid-bass speakers or subwoofers only. The amplifier is 1-ohm stable (1500 watts x 1) and will drive a pair of 4-ohm DVC subwoofers or quad-configuration of 2-ohm DVC subwoofers with ease.

Class bd Design: 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. This means, more power from your amplifier with less drain on your vehicles electrical and charging system.

Constant Power: Its proprietary "Constant Power" configuration provides the ability to instantaneously deliver maximum output power to speakers without regard to its varying impedance while maintaining high-efficiency and thermal performance. Music and speakers have a dynamic relationship. So your listening experience is cleaner, louder and more impressive than ever before.

Cast Aluminum Heatsink: The cast aluminum heatsink dissipates heat generated by the amplifier's circuitry. The inherent advantage of casting provides a 30% improvement of cooling over conventional extrusion heatsink designs.

Dynamic Thermal Management (DTM): DTM Evenly distributes excess heat across entire amplifier heatsink.

DSM (Discrete Surface Mount): DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature. An industry-leading manufacturing process, DSM utilizes high-speed robotics, high-quality 1% tight-tolerance parts and large board traces. The discrete components are laser etched to meet a particular value and a very low tolerance. This lower tolerance improves the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

TO-247 MOSFETs: The Rockford Fosgate amplifier 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 many other amplifier. The MOSFET transistor is the best type of device to use when building a high quality mobile amplifier. The TO-247 has 60% more metal tab area and its unique, fully encapsulated design is capable of housing a silicon die (the heart of the MOSFET) twice as large as the TO-220. The larger die provides more power handling capacity. Additionally, the extra metal tab area ensures that no matter what size silicon die is inside, the thermal impedance will always be lower than in the TO-220 due to improved heat dissipation.

MEHSA3: MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span. MEHSA3 (Maximum Efficiency Heat Sink Application - gen. 3) is a proprietary process that yields up to five times better heat transfer than traditional FET mounting techniques, using the exact same components. A multi-layer insulated metal substrate operating with minimal thermal resistance spreads heat both downward and outward to quickly dissipate heat from each device across the heatsink. This process combined with Rockford's optimized heatsink designs, DSM (Discrete Surface Mount) technology and MOSFET devices, allows the amplifier to squeeze more watts per cubic inch from every output device as well as provide consistent thermal stability. The 3rd generation creates a dielectric layer between the ceramic topside and the aluminum base that retains all of the electrical isolation and capacitive coupling of the original MEHSA material increasing it's thermal conductivity. The higher power handling results in a 20% reduction in thermal impedance.

NOMAD (NOn-Multiplying Advanced Decision): NOMAD is an intelligent protection circuit that uses an analog computer to make real time decisions regarding temperature, voltage, current and impedance. The unit is protected without limiting sound output unless needed.

Power and Protection LEDs: The LEDs are located on top of the amplifier. A blue Power LED illuminates when the amplifier is turned on. A red Thermal LED illuminates if the amplifier overheats. The yellow Protect LED illuminates if a short circuit or too low an impedance is detected at the speaker connections. When any of the protection circuits engage, the amp automatically shuts down until the problem is corrected.

Controls

Internal Crossover: The amplifier features a built-in 24dB/octave Butterworth low-pass filter with a variable crossover point from 35Hz to 250Hz.

Punch EQ2: The Punch EQ on-board equalization circuit helps correct for acoustical deficiencies in the listening environment. This control is a narrow band adjustment variable from 0dB to +18dB at 45Hz with a Gyrator based Punch EQ that eliminates frequency shift with boost.

Infrasonic Filter: This 28Hz high-pass filter (12dB/octave Butterworth) is designed to prevent frequencies below the audio range from being applied to the subwoofer from the amplifier. This infrasonic filter improves your subwoofer performance and power handling, particularly in vented enclosures.

Connections

Power Connections: The power and ground terminals are nickel-plated captive c-clamp wire connectors and will accommodate up to 4-gauge wire. An external 200-amp fuse (not included) must be installed on the power wire. If a wiring kit is used which includes a fuse with a value other than 200-amps, the original should be replaced with a 200-amp fuse. The remote turn-on terminal will accept wire sizes of 12- to 24-gauge. A Phillips-head or slotted screwdriver (not supplied) is required to tighten/loosen the terminals.

Dual Speaker Terminals: The Power mono-amplifier features two pair of speaker output terminals so you can easily connect two 4-ohm speakers to the amplifier in a 2-ohm load configuration. The two pair of nickel-plated clamp wire connectors will accept 8-gauge to 18-gauge wire. A Phillips-head or slotted screwdriver (not supplied) is required to tighten/loosen the terminals.

Differential Input RCA Inputs: The amplifier features a pair of differential RCA input jacks for easy connection of signal level input. Differential input circuitry measures the voltage of both the positive (+) and negative (-) portions of the input signal, subtracting the voltage common to both conductors (noise); resulting in a cleaner signal. Reducing the noise on the input then improves the sound quality of the output. The RCA input jacks are nickel-plated to resist signal degradation caused by corrosion.

RCA Outputs: The amplifier also features a pair of RCA "Pass-Thru" jacks which provide a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the rear amplifier location. The RCA output jacks are nickel-plated to resist signal degradation caused by corrosion.

Remote Punch EQ (PEQ) Connection: An RJ-45 jack is provided for connecting an optional remote PEQ control (575ROCKPEQ, sold separately). If you use the remote PEQ, the Punch EQ control on the amp is disabled, and replaced by the remote.

Note: Previous model Punch Bass and Para-Punch remotes will not work with this amp.

I have this amp hooked to a Rockford Fish are T2S2 13 2000 way RMS sub. I have it in my Semi tractor trailer. I use it 16 hours a day and 6 days a week. It does not get to hit and it has never shut down for to high of temp. It has a massive heat sink so it needs a lot of air space around it to cool the amp. I have had 2 of the T500-1BDCP and 1 of the T1000-BDCP amps. I never had a problem with any one of them. Give them air space and you should be fine.
[ NICK  Apr 09, 2018 ]
