Most car amplifiers have a<br />
feature called "bridge mode,"<br />
where two channels can be<br />
combined as one channel to<br />
produce maximum output<br />
power. Just imagine, you’re<br />
looking to power a 200 watts RMS<br />
rated 4-ohm sub, but you are<br />
trying to avoid purchasing an<br />
expensive mono amplifier. You<br />
can take a small 2-channel amp<br />
that normally puts out two<br />
channels of 60 watts RMS<br />
and bridge it to produce around<br />
120 watts RMS, which would be<br />
perfect for your needs. Thsi is<br />
done by using the negative<br />
signal from one channel with the<br />
positive signal of the other<br />
channel, effectively doubling<br />
what each channel alone could<br />
output through a 2-ohm load.<br />
Usually, this is the maximum<br />
wattage of the amp. This way<br />
you're also optimizing your<br />
system's power potential.
