Why iPad sounds so weak to external speakers

[db123]

I have a 40 watt RMS speakers which can shake my apartment but when I connect it to iPad thru 3.5 mm jack/Bluetooth , it's very feeble...I am really surprised !!!

Turn up the iPad's volume all the way. If you live in an area that limits the headphone volume, you aren't getting enough power through the headphone jack.

They are better ways of connecting a stereo to a iPad/ipod. The line out from the dock is one.

The ipad will also accept most USB DACs for a digital output.
