Audio system power question
Im looking to install a system on my Road king 2021, just worried about the battery draining.
I have a razor tour pak with the Advanblack speaker lid (2 x 8" speakers + 2 tweeters) and the saddlebag 8" speaker lids + 2 tweeters
2 x speaker pods mounted on the crash bar for 6.5" speakers
The below is what im thinking. Could anyone advise if the battery and alternator will keep up or should i be looking at additional high output alternator and adding in a battery?
thanks in advance

You're gonna run 8 speakers and 4 horns off a 400 watt amp??
To answer your question, there are guys pushing way more watts than that on a stock battery. I have 4 6.5 speakers and two horns pushing around 1300 watts on my stock battery with no issues.
I think you're gonna need more amp though.

You really need AT least 125 watts per speaker..more from the rear if you can....
I'm not familiar with those speakers, but just looking at the RMS watts, they should be able to handle that at least. Or close to it.

Gotcha. I dont wanna say that brand is good or bad, since I have no clue. Id still plan out your system to get enough watts to each speaker. based on those specs provided.
