how can I increase the efficiency of my sony car amplifier?
power 250 w, 1 channel is connected to subwoofer, the other channel is now not connected. I need extra bass
Some posibilities for more (louder) output without upgrading the amp:
1. Use a dual voice coil subwoofer connected to both amp channels,
2. Use the stereo amp in Bridged Mono mode (if available),
3. Get a subwoofer that is more efficient (higher SPL rating),
4. Get a subwoofer that operates at the lowest recommended impedance rating (minimum ohms) of the amp,
5. Place the subwoofer in a more efficient enclosure,
6. Use shorter and / or larger wires between the battery and amp,
7. Use shorter and / or larger wires leading from the amp to the subwoofer,
8. Install a large filter capacitor on the power supply lines near the amp,
9. Use an audio compressor before the amp to increase the average signal level of the program material (a cheat).
