I can do a trade for a iphone Xr or newer model. Rockford Fosgate 12 inch sub punch MTX RT 251D Road Thunder amp Rockford Fosgate Punch 801s 2400 W Both amps and sub work perfect, nothing wrong, solid box. This amp is worth every penny you spend on it. It not only looks good, put it provides some serious power. At the top of the Punch Series power chain, the Rockford Fosgate 801S amplifier pumps out 200 watts RMS per channel at 4 ohms, or a brutal 800 watts RMS x 1 in bridged mode. Innovative circuitry, MOSFET power, and proprietary technology bring out extraordinary detail in your music, driving your subs with precision and strength you just can't get from a lesser amp. 200 watts RMS x 2 at 4 ohms 400 watts RMS x 2 at 2 ohms 800 watts RMS x 1 bridged output at 4 ohms stereo or bridged mono output 4-ohm stable in bridged mode Tri-Way capable 50-250 Hz high-pass/low-pass (12 dB/octave) crossovers MOSFET power supply and output devices MEHSA mounting technology increases the heat transfer from the MOSFET output devices to the heat sink, for higher power output, lower operating temperatures, and greater reliability TOPAZ noise-killing differential inputs that eliminate 80% of ground loop noise. Transana circuitry keeps preamp voltages low and signal paths simple for outstanding audio quality NOMAD advanced protection circuitry for "intelligent" shutdown protection wired remote included for fingertip control of Punch Bass (0-18 dB boost at 45 Hz)
