      Detailed Model Analysis into Low-Impedance Loads Sunfire 300x2 (Two-Channel) The 1-Ohm Workhorse: Of the models listed, the 2-channel 300x2 is the most unconstrained when driving extreme 1 to 2 Ohm loads. Because the power supply only has to feed two channels rather than five or seven, it cleanly doubles continuous power down to 2 Ohms (1,200 W / ch} and handles 1 Ohm continuous/transient dips without tripping thermal or over-current protection. Current Burst: Capable of delivering over 100 Amperes peak-to-peak current into ultra-low impedance dipoles. Sunfire 200x5 & 200x7 Behavior into 2 Ohms: Both the 200x5 and 200x7 platforms are rated to double power into 4 Ohms and double again into 2 Ohms per channel. The AC Wall Line Bottleneck at 1–2 Ohms: When driving 5 or 7 channels into 2 Ohms simultaneously, the bottleneck is rarely the amplifier's internal transistors—it is the 15 Ampere household AC wall circuit. Under maximum output into 1 to 2 Ohm speaker loads, a multi-channel Sunfire can easily attempt to draw 2,000 to 3,000 watts from the wall, which will trip standard home circuit breakers unless fed by dedicated high-amperage lines (20). Sunfire 400x7 (Theater Grand / TGA 400-7) High-Voltage / High-Current Titan: Delivering 400 RMS into 8 Ohms and 800 W RMS} into 4 Ohms} across 7 channels, the 400x7 produces tremendous current output. Low-Impedance Limits: While internal tracking downconverters comfortably process 2 Ohm loads, operating this amp heavily into 1 to 2 Ohm speaker configurations requires robust power conditioning and high-current AC mains wiring to avoid line-sag. 4. Key Operating Tips for 1–2 Ohm Loads Terminal Selection: Always use the Voltage Source outputs for ultra-low impedance, high-current speakers. The Current Source output inserts a $1\text{ Ohm}$ internal resistor in series, which increases total output impedance and degrades damping factor on already low-impedance loads. AC Mains Requirement: To run Sunfire amps into 1 to 2 Ohm} loads at high volume without tripping house breakers, plug the amp directly into a dedicated 20 Amp AC circuit rather than a shared power strip or standard 15 Amp outlet. Capacitor Maintenance / Service: Because these units are aging, their internal energy-storage capacitor banks and tracking downconverter timing circuits should be inspected. Servicing (e.g., re-capping power supplies via specialized technicians) ensures the amplifier maintains its full 80-100 A peak current delivery capability without rail imbalance.
