Features

Overview: With its super efficient Class-BD circuit topology, the Rockford Fosgate T2500-1bd 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 (2,500 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. Punch 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.

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.

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.

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.

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

Mode Switch: This function is used to set the amplifier between single amplifier use, and Master or Save for when connecting multiple bd amplifiers together. The first amplifier in the series should be set to Master and the subsequent amplifiers set to Slave. This allows one gain, crossover, infrasonic filter, and bass boost setting for all daisy-chained amplifiers.

Internal Crossover: The amplifier's internal crossover has a 24 dB/octave slope. The crossover point is variable from 35Hz to 250Hz.

Punch EQ: Punch EQ acts as a variable bass boost; 0-18 dB at 45 Hz.

Infrasonic Filter: The infrasonic high pass filter is designed to prevent frequencies below the audible range from being applied to the subwoofer from the amplifier, consequently improving subwoofer performance and power handling, particularly in vented enclosures. The crossover point is fixed at 28 Hz, the slope is 12 dB/octave, and the filter can be turned on or off to suit your preference.

Phase Switch: This feature is used when bridging two bd amplifiers together using a bd Sync cable (sold separately) to phase one amplifier 180-degrees from the other when driving a common load.

Connections

Power Connections: The power and ground connections are nickel-plated set-screw wire terminals and will accommodate up to 1/0-gauge wire. An external 300-amp fuse (not included) must be installed on the power wire. The remote turn-on terminal will accept wire sizes up to 8-gauge. The supplied hex-key is required to tighten/loosen the terminals.

Speaker Connections: The nickel-plated set-screw speaker terminals will accept wire sizes from 16 to 8-gauge.The included hex-key is required to tighten/loosen the terminals.

Note: Although there are two sets of speaker terminals, the amplifier still produces a monaural signal. The A and B speaker outputs are internally wired in parallel.

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 (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.

bd Sync Connection: This amplifier has a proprietary 6-pin mini-DIN connector. When operating two of these amplifiers together in a bridged mode, a bd Sync cable (sold separately) must be used. This will allow the two independent frequency carrier generators in each unit to b synchronized.
