Was planning to add 2-channel amp to front speakers. Has anyone done this?
Already have an amp and a line out converter.




Thanks for helping a noob.

 

The simplest way would be to get a radio harness adapter and the factory wiring adapter. I think Scosche and Metra make both. One goes to the factory dash harness and one plugs into the back of the radio. Then connect all of the wires directly across to eachother except the front speaker wires. The ones that come from the radio side of the harness you would connect to the LOC. Then connect the RCA out of the LOC to the amp and then wire the amp speaker outs to the dash harness side of the wiring harness adapter. This way you won't even have to open up your doors and run wire to them.

 

Why would you want to do such a thing? The stock speakers are only 20watt rms and 50 max? What would be the point? Also, I think it would make more sense to do it for the rear speakers. There power range is the same, but the frequency range is much lower.

 

You do not want to do it to the rears. Rear fill is not as important and they arent components. They are coaxials. But if you are going to power the fronts, I hope you are powering aftermarket fronts. The stock ones wouldnt be worth the money and hassle.

 

I agree that amping the stock speakers is a waste. However, I still think that he should amp the rears. It's simple power consumption laws........

Frequency max power above that frequency
300 hz 50%
600 hz 25%
1200 hz 10%
2400 hz 5%

What that says is that frequencies below 300 hz will require 50% of the overall system power. This is because to make frequencies below 300hz you have to move alot of air. You don't have to move it fast, you just have to move alot of it. Therefore you need big cones. Big cones means big woofers. And moving big woofers means that you'll have to use lots of power to do it.

NOW........because the frequencies of the rear speakers are lower then that of the front, it doesn't make much sense to amp them. Granted, rear fill isn't AS important to overall system sound, that doesn't mean that he should throw an amp on his highs. Also, as far as coaxials and components are concerned, yes it's true that he might get a slightly better sound out of amping the fronts. But that's only at low volume. Once he hits higher volumes, he runs the risk of blowing the front tweeters.
