Quick Answer

Choose the PT1000 if you need dedicated power for a subwoofer; choose the R1004 if you want to power multiple full-range speakers in a 4-channel setup.

Power and Channel Configuration

The PT1000 is a 2/1 channel amplifier, meaning it can run as a mono block for a subwoofer or as a 2-channel amp for midrange speakers. The R1004 is a dedicated 4-channel amplifier, ideal for powering a full set of front and rear speakers or a pair of speakers bridged for more power.

If you're building a system with a subwoofer and want a single amp to drive it, the PT1000's mono capability with bass boost and remote subwoofer control is a clear advantage. For a multi-speaker setup without a sub, the R1004's four channels give you flexibility.

Inputs and Tuning Features

Both amps include RCA and speaker level inputs, so they work with factory or aftermarket head units. The PT1000 adds high-pass and low-pass filters, bass boost, and a remote subwoofer control for fine-tuning low frequencies. The R1004 has variable gain control and a power LED, but lacks the dedicated subwoofer controls.

If you need to shape your bass response precisely, the PT1000's filter and boost options are essential. For a straightforward full-range system, the R1004's simpler controls keep installation clean.

Build and Protection

The PT1000 features a PWM MOSFET power supply and thermal, short, and overload protection circuits, making it robust for demanding subwoofer duty. The R1004 is a Class A/B design from the Riot series, rated at 400 watts total, with no mention of MOSFET or advanced protection circuits in its specs.

If you plan to push the amp hard or run it in a marine environment, the PT1000's protection suite offers extra peace of mind. The R1004 is better suited for moderate, protected installations.

Trade-offs at a Glance

  • Channel Count: PT1000: 2/1 channel (mono or stereo). R1004: 4 channels. Choose PT1000 for subwoofer, R1004 for multiple speakers.
  • Bass Control: PT1000 has HP/LP filters, bass boost, and remote subwoofer control. R1004 has variable gain only. PT1000 gives you precise low-end tuning; R1004 keeps it simple.
  • Protection Circuitry: PT1000 includes thermal, short, and overload protection plus PWM MOSFET power supply. R1004 does not list these features. PT1000 is better for demanding or marine installations.
