Frequently Asked Questions about Prime R2-750X1 (B-stock)

What is the RMS continuous power of the Prime R2-750X1?

The Rockford Fosgate Prime R2-750X1 offers an impressive RMS continuous power, provided in three different impedance levels: 250 watts at 4 ohms, 500 watts at 2 ohms, and 750 watts at 1 ohm. This means that this amplifier is designed to deliver consistent and overwhelming performance in various installation scenarios, whether you are running a single powerful Subwoofer or a more complex setup. The versatility of the power settings allows you to get the most out of your car audio system by utilizing the dynamic power of the Prime series.

What dynamic power does the Prime R2-750X1 deliver?

The Prime R2-750X1 from Rockford Fosgate produces a dynamic power of 300 watts at 4 ohms, 545 watts at 2 ohms, and 830 watts at 1 ohm. This dynamic power describes the amplifier's ability to deliver short-term peak loads and ensures that the music remains clear and powerful even during moments of high intensity. Especially during bass drops, this amplifier can meet greater power demands without audible distortion or loss of performance. This dynamic load capability extends the effectiveness of the amplifier beyond the static RMS powers.

How does signal integration work with this amplifier?

The Prime R2-750X1 amplifier uses balanced differential inputs and offers both low-level RCA and high-level 4-pin Molex inputs. This is ideal for integration into both factory and custom audio systems. Additionally, there are pass-through RCA outputs that allow the user to route the signal through the system and easily add more amplifiers. This enhanced signal processing enables seamless and lossless integration, regardless of the existing audio sources and configurations.

What filter functions does the Prime R2-750X1 offer?

The amplifier is equipped with fully adjustable 12 dB/octave Butterworth crossovers, allowing both high-pass and low-pass filters. The low-pass filter is adjustable from 50 Hz to 250 Hz, while the subsonic filter handles frequencies from 15 Hz to 40 Hz. These fine-tuning options ensure that only the desired frequencies are sent to the speakers, minimizing distortion and optimizing sound quality. For clear and punchy bass, a punch EQ control is also integrated, which can be set from 0 to +18 dB at 45 Hz.

What are the key dimensions for installing the Prime R2-750X1?

The dimensions of the Prime R2-750X1 amplifier are 4.9 cm in height, 17.3 cm in width, and 25.5 cm in depth. These compact measurements make installation easier in a variety of vehicles. Especially when you have limited space, this compact format offers the flexibility to mount the amplifier under seats or in trunk compartments without taking up much storage space. When installing, always consider the size of the installation location to ensure proper airflow and cooling for optimal performance.

How is the cooling of the Prime R2-750X1 handled?

The Prime R2-750X1 amplifier uses a convection cooling system integrated into an aluminum cast heat sink. This design maximizes heat dissipation by increasing the surface area for heat distribution, which is particularly important under higher current loads. Aluminum has high thermal conductivity, ensuring the operational stability of the amplifier even under demanding conditions. For added safety, the amplifier is equipped with short-circuit and overcurrent protection to safeguard the amp against thermal overloads.

What safety measures are integrated into the Prime R2-750X1?

The Prime R2-750X1 features several protection mechanisms to safeguard both the Amplifier and the connected audio equipment. These include short circuit and overcurrent protection, which secures the Amplifier against electrical hazards and helps prevent internal damage from unwanted power surges. Furthermore, the Amplifier is both CEA-2006 compliant and CE compliant, meaning it meets strict safety and performance guidelines. These measures promote reliable performance and longevity of the Amplifier.

What input sensitivities does the Prime R2-750X1 support?

The Prime R2-750X1 supports an input sensitivity of 150 mV to 4 V in the low-level range and 450 mV to 12 V in the high-level range. This wide range allows the Amplifier to be integrated into various audio systems, whether they are factory-installed or custom systems. This adaptability is particularly useful for car audio enthusiasts who want to easily adjust the Amplifier to their existing system levels to achieve the desired sound performance.

How does the C.L.E.A.N. setting help with the Prime R2-750X1?

The C.L.E.A.N. setting (Clipping Monitor) on the Prime R2-750X1 is an innovative technology that helps you optimally set the Amplifier to avoid distortion. It indicates when the input signal reaches clipping points, making it easy to adjust the ideal input gain. The goal is to maximize sound clarity while minimizing any risk of distortion that could affect speaker performance. With this feature, you ensure clear, uncolored sound.

What cable diameter is recommended for wiring the Prime R2-750X1?

For the power wiring of the Prime R2-750X1 Amplifier, a cable diameter of 20mm² is recommended to ensure the necessary current flow. For speaker wiring, you should use a cable with a diameter of 8mm². These cable sizes are necessary to minimize current loss and ensure a stable power supply, which is particularly important for the Amplifier's power demands. In addition to performance, the correct cable size is crucial for preventing overheating and ensuring the system's operational safety.

Es lohnt sich!

Ich habe sie an den Sounddigital 800.4 Evo6 angeschlossen. Und ich bin mehr als zufrieden. Mitteltöner laut und auch präzise. Hochtöner brennen nicht in den Ohren, die sind laut und geben das, was sie sollen. Gut angelegtes Geld.

Laut ... einfach nur laut

Also ich sag es mal so... wenn man ein Lautes Kompo System sucht, mit noch sehr guten Klangeigenschaften.
Naja der sollte das T3 von Rockford nehmen.
Ich hatte viele Systeme verbaut und bin dann wieder zurück zum T3 und habe nun 3 verbaut... schön laut und sehr feiner Klang.

vibe powerbox65.4m v7 samen met quadlock connector besteld.

Levertijd prima in orde.

vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.

Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.
