Hello forum.

Given I have a mono system with one

Subwoofer
600 watts RMS
8 ohms

and one

Top box
165Watt RMS
8 ohms

powered by a 12V 90AH battery. Thomann recommends that the output Watt by the Amp should be larger then needed in order to avoid clipping.

I own a Pioneer GM-D8704, it spits out 2 x 300W bridged. That would work for the top box, but for the sub ??

What choice would you make? Go for 1-Channel Amp?

You got the amp so try it, if it gets loud enough you're good. A larger amp with double the power would only get slightly louder but might cut the run time in half.

Even so, I still risk clipping and damage to some components. Especially when I want to play loud ...

"What choice would you make? Go for 1-Channel Amp?"

Or something stereo that will give you around 1kW bridged. It seems simple enough.

Well - you really need a crossover as well. Or find an amp/s with filters on it already, eg at least a low-pass for the Tham.

You'll damage components even faster with a bigger amp if you don't know enough to stop pushing when the amp is out of gas.
