Anybody know what the RMS is on each speaker in an A3 (8P), fronts and rear. I want to buy an amp to power all 4 speakers and a sub. I will be changing the stock sub, and removing the HU. Then replacing the HU with a screen that doesnt have a built in amp, hence a 5 channel amp. At the moment just trying make a plan. Not sure on spec off amp, but need to know RMS of speakers. Also I know that i can get the rear speaker channels from the red connecter that the standard sub+amp use, but want about the front speakers? Were can i give its audio signal. Any more cables in the back i can use, or do they get it from the front ISO? Cheers.
