Quick answer
Choose the CE102 for a budget-friendly, compact 2-channel amp for basic full-range speakers. Choose the R4002 if you need more power, 2-ohm stability, bass boost, and remote subwoofer control for a more flexible system.
Power and impedance: CE102 vs R4002
The CE102 delivers 100 watts total power and is 4-ohm stable, making it a solid choice for powering a pair of coaxial speakers or a small subwoofer in a basic setup. The R4002 steps up with 2-ohm stereo stability and a PWM MOSFET power supply, which means it can handle more demanding loads and deliver cleaner power to lower-impedance speakers or multiple drivers.
If you plan to run a 2-ohm subwoofer or want headroom for future upgrades, the R4002's power supply and stability give it a clear advantage. For a simple, low-cost 4-ohm system, the CE102 gets the job done without extra features you won't use.
Features and control: what you get with each
Both amps include RCA and speaker level inputs, plus high-pass and low-pass filters, so you can integrate them with factory or aftermarket head units. The R4002 adds bass boost, a remote subwoofer control, and an illuminated logo. It also includes thermal, short, and overload protection circuits for added reliability.
The CE102 keeps things simple with just the essential filters and inputs. If you want to fine-tune your bass from the driver's seat or need extra protection in a demanding install, the R4002's extras are worth the higher price.
Trade-offs at a glance
- Power and impedance: CE102: 100W total, 4-ohm stable. R4002: higher power, 2-ohm stable, PWM MOSFET power supply.
- Features: CE102: basic filters and inputs. R4002: adds bass boost, remote subwoofer control, illuminated logo, and protection circuits.
- Price: CE102 is significantly cheaper (catalog price $23.33 vs $88.72). R4002 costs more but includes more power and features. If budget is your top priority, the CE102 delivers essential performance at a low cost.
