Rockford Fosgate RFI2SW Speaker Line To Male RCA Adapter
Speaker Line to Male RCA Adapter OFC, Platinum Plated Ends, Split Center Pin. Connects Factory OEM Source Units to Amplifiers Without RCA Outputs.
Product Overview
The Rockford Fosgate RFI2SW is a high-level speaker wire to male RCA plug adapter the male-output counterpart to the RFIF2SW female adapter. Where the RFIF2SW outputs female RCA jacks (requiring a separate RCA cable to the amplifier), the RFI2SW outputs male RCA plugs that connect directly into the amplifier's female RCA inputs without an intermediate cable. OFC conductors, platinum-plated ends, and a split center pin for secure plug engagement.
Key Specifications

Features & Benefits
- Male RCA Plug Output — Direct Amplifier Connection The male RCA plugs on the RFI2SW plug directly into the amplifier's female RCA input jacks — eliminating the need for a separate RCA signal cable between the adapter and the amplifier. This is the key distinction from the RFIF2SW (female output), which requires an RCA cable between adapter and amplifier.
- OFC Conductors + Platinum Plated Ends OFC resists oxidation at both the speaker wire connection and RCA plug ends for long-term low-resistance signal transfer.
- Split Center Pin The same split center pin design used throughout the Rockford Fosgate RFI and RFIT RCA cable range — six-point spring contact for a secure, vibration-resistant connection at the amplifier's RCA input.
- Factory Head Unit to Amplifier — Economic Solution Connects a factory OEM source unit (without RCA outputs) to an amplifier using the existing speaker wire outputs.

Frequently Asked Questions
What is the difference between the RFI2SW and the RFIF2SW?
Both are high-level speaker to RCA signal adapters with identical OFC and platinum construction. The RFI2SW has male RCA plugs — it connects directly into the amplifier's female RCA input jacks without requiring a separate RCA cable. The RFIF2SW has female RCA jacks — it requires a separate RCA cable between the adapter and the amplifier.
Can the RFI2SW damage my factory head unit?
The product description explicitly warns that improper installation can damage the source unit — consult the installation instructions before connecting to any factory head unit. Some OEM head units are sensitive to the impedance loading of external adapters on their speaker outputs.
Does the RFI2SW replace a line output converter (LOC)?
A basic adapter like the RFI2SW passively converts the high-level signal. For sensitive factory head units, a dedicated line output converter with level-matching circuitry may provide better protection and a more balanced signal. Confirm the appropriate solution for your vehicle's head unit with your installer before purchasing.
How many channels does the RFI2SW provide?
Channel count is not confirmed in the supplier data. Confirm from the official Rockford Fosgate RFI2SW product page. The "2SW" designation suggests a 2-channel (stereo) output.
Which adapter should I choose — RFI2SW or RFIF2SW?
Choose based on your installation layout. The RFI2SW (male output) plugs directly into the amplifier — best when the adapter can reach the amplifier's RCA inputs without slack. The RFIF2SW (female output) requires an RCA cable between adapter and amplifier — best when distance or routing requires a separate cable run.
