A quick and simple answer: no.

The amps operate off the same power supply. Otherwise, it would have been
possible to "stack" the amps in series. Although I'm not sure that would be
a stable solution.

You need a higher power supply voltage to get more power, or lower your
speaker's impedance (paralleling two or more drivers), but then make sure
the amp can handle the increased current.

| Hi All
|
| Look at the attached drawing taken from Sam Electronic Circuits web site.
| Is it possible to connect the two ALREADY bridged amps together to gain
more
| power?
| right now each amp deliver 18W, I want to gain 36W and more (mono).
| circuit is operating via car battery (12Vdc) so high current consumption
| isn't an issue.
