Rockford Fosgate Power 350S (Desperately in need of Repair)
I desperately want to repair this car amplifier!
I desperately ordered two 330uf 63v capacitors off ebay already. Now I desperately need to find out that model these poor burnt out MOSFET are... if they are called MOSFET. MOSFET Q6 & Q7 busted & burnt! If it is a good idea just to replace all them MOSFETS. MEHSA thermal management system QM-1696r-I ![]() ![]() ![]() ![]() ![]() ![]() Last edited by sherwind2010; 05-18-2016 at 05:54 PM. |

I don't know if this helps, specs for the Rockford Fosgate Power 350S...
SPECIFICATIONS Signal-to-Noise Ratio >100dB A-weighted Crossover Slope 24dB/octave Butterworth Crossover Frequency variable from 50Hz to 250Hz Frequency Response 20Hz to 20kHz ±0.5dB Bandwidth 20Hz to 200kHz ±3dB Damping Factor @ 4Ω (at output connector ) >200 Slew Rate 30 Volts/ms IM Distortion (IHF) <0.05% Acceptable Signal Voltage Range Variable from 250mV to 6V (RCA) Protection NOMAD - Internal analog-computer output protection circuitry limits power in case of overload. Thermal switch shuts down the amplifier in case of overheating. Equalization (45Hz Punch Bass) Variable from 0dB to +18dB @ 45Hz Input Impedance 20k ohms Continuous Power Rating (RMS) - Measured at 14.4 Battery Volts 4Ω Load Per Channel 87.5 Watts x 2 2Ω Load Per Channel 175 Watts x 2 4Ω Load Bridged (Mono) 350 Watts x 1 Battery Fuse Rating (Amp) 30A ((The Amp was working with the broken power supply transistors up tell the reverse polarity, before the amp got really hot.))
