I dont know if im posting this in the right spot, but i found these DROK amp kits on amazon that make 34 watts on two channels. I was wondering is i could wire the two channels in parallel to make it one 68 watt channel. heres the link: http://www.amazon.com/DROK-TDA2030A-Digital-Amplifier-Channel/dp/B00D2QRM0A/ref=sr_1_2?ie=UTF8&qid=1433279029&sr=8-2&keywords=diy+amplifier
Nope
At first, paralleling output would not rise output power, simply because output voltage stays the same.
And second, it is no good idea to parallel amp outputs anyway. This can cause instabilities and strange behaviour.
To get more output power, the only way is adding more supply voltage.

You can bridge the 2 amps to get twice as much power.
Invert the input into one of the amps and take the outputs from each amp to a speaker.
Be aware that if the normal amps are rated into 4 ohms then bridged you cant go below 8 ohms.

Hi,
As it is already BTL you can't bridge it any further.
Parallel with 0.22R on all outputs is 68W into 2R.
You must include the series resistors before paralleling.

My mistake.
Take a look at this one with more power.
