Stock Amp Wattage - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

BigJyoungblood · 05-02-2013, 12:34 AM

I know they say "300w" pioneer stereo, but what is the wattage being sent to the front door 6.5"? I have searched and came up empty handed so any help is greatly appreciated!!

300w peak, I don't think they are anymore than 75w rms. I could be wrong

I would imagine that peak 300w would include all 8 speakers and not just the door speakers.

To maximize clear headroom, I turn my radio up 100% and control the svc levels about -10db

It does control all speakers, I checked the connector that connects to the stock amp and you have 4 pins with 5v on them.
Also in your HU you have that option " hear, feel, natural" or whatever .. Those are basically the controls for the amp

The amp does not control all speakers. It powers the door speakers only, the head powers the dash and rear speakers.

I know this, but how many watts is it sending?

not sure on that, I would estimate 35w per side tho. Its at 2 ohm as well so not really worthwhile to reuse

I've pulled the amp apart, there's nothing that says anything other than load. I've ran all the numbers from the case and board, none come up to any worthwhile info

The amp does control the speakers , when I had mine disconnected I tried playing songs with the connector off , no volume , connect it again and speakers work .

So the head unit is powering the dash speakers, tweeters and the rear speakers. So a total of 6 speakers?

Correct, the midrange and tweet on the dash are in series for a 4ohm load, rear speakers are 4ohm. then the Midbass runs to the amp with a 2ohm load.

Stock deck puts out 50x 4 at peak approximately 20 rms and the amp for the doors is the remainder divided by 2.
