Do I need to change the stock speaker on my rear doors too? Once again Sir jhnkvn, many thanks for taking time to answer all my noob questions. You are very helpful to us newbies.
Amplifier performance is hard to quantify kasi. Every manufacturer rates their amplifiers in a different way that's why I don't even bother looking at the other data at all unless CEA certified sila.

The Sonus Ecstatic retails at sub-10,000php and outputs 100W x 4 at 4ohms. On why it throws up a lot of power -- it's because it uses Class D amplifier topologies. These are way more efficient than their more mature Class A/B but also comes with their own drawbacks.

Like I said in my previous post,
For the more affordable crowd, I'll still recommend Class A/B amplifiers over D because Class A/B amplifiers have been around in the market longer.
But since Sonus is being distributed by giants of our local car audio industry, I doubt they would have designed and contracted it poorly. So what's better between the two? Do a coin toss or just pick one that you like more. Audiosystem has brand gravitas with it and I'll go with it in this case since 75W versus 100W isn't a lot really.

Do you need to change your rear speakers?
Only if you want to upgrade them. I'm not particularly fond of rear-upgrades since I usually drive my car.
