Hey!
I have a outdoor stereo that runs on:
1x 2 x 100 Watt 6 Ohm Class D Audio Amplifier Board TDA7498 | eBay
1x 4 x 100Watt Class D Audio Amplifier Board TK2050 | eBay
It is a 3way system and I am using a Electronic Crossover to control it.
I am thinking of to change to the GM-D8604 - Class FD 4-Channel Bridgeable Amplifier | Pioneer Electronics USA
And wire it through 4 channels instead. The bass on one channel and the mids and tweeters on the same with maybe a passiv crossover for the tweeters.
The question is how efficient is the Pioneer GM-D8604 compared to what I am using now? I saw the max power consumption is 30A. I have my system now fused on 7A, and it has not burned. Can the Pioneer just push out more power or is it a little less efficient?
The system is now running on 24V through 2x 12V car batteries on 74ah each.

Something around 70-80% at full load is considered good and typical for these class d car amplifier, don't expect more. The amplifiers you currently have have a efficiency of about 90-95%.
But the important part is that they only have a quiescent current of around 50mA each while class d car amplifiers typically have around 0.5-2A, because they have to step up the 12v car voltage to around 40v.
I would suggest you to just buy another car battery to get 39v, this will double the maximum power of your tda7498 compared to 24v.
