If you are underpowering the speakers or subwoofers connected to your car amplifier, but don't want to purchase a more powerful amplifier, you can make your existing setup sound stronger. Making your current car amplifier more powerful will allow it to perform to its optimal standards and provide you with a more better car audio listening experience. Today you will learn all about the different ideas to make your car amplifier sound more powerful all without upgrading it.
1) Have a strong electrical system. The maximum rms power the mosfet transistors produce are rated at 14.4 volts. If you have a weak alternator and battery setup, your car audio system will suffer from voltage drops. So the voltage will not be a consistent 14.4 volts it could drop to around 12 volts. This can limit the final output power of the amplifier is pushing out. Its suggested that you connect a inline volt meter to measure the voltage to see how low its dropping when the bass kick in.
For example, a car amplifier is rated at 500 watts rms @ 14.4 volts, if your vehicle electrical system puts out around 12-13 volts intermittently, the car amplifier will not push the full 500 its rated around all the time. The most you would probably will get is around 350-380 watts rms. This is why its important that you consider a higher amp alternator, do the big three upgrade and add a couple of deep cycle batteries to maintain the voltage. Also ensure that you are using the correct gauge wiring kit for your amp. 0 gauge thick power and ground cables will provide the best current to the car amp to also contribute towards stopping voltage drop.
2) Lower the final ohm impedance. The lower the ohm load is on the amplifier, the less electrical resistance created, therefore it results in more power. There are different wiring diagrams that show how to wire dual or single voice coils in series or parallel for the ohm load you want to create. The lower final ohm load the better because it means your amp will push out more power. But make sure you find out what ohm load the amp is stable at or it will automatically go into protection mode.
3) Bridge the car amplifier. This is a good idea to get more out of your car amplifier if its a two channel amplifier. Basically what you can do is join the two channels together creating a bridge to create one channel. For example, a Rockford fosgate amplifier is rated at 2 X 250 watts rms, bridging it will provide 1 X 1000 watts rms. Realistically this is ideal for single subwoofer enclosures setups and will double the power your amp can put of easily.
