Head Units
Learning about car audio. I love my factory head unit. Do I have to change it?

[QUOTE="Kickstand, post: 8740746, member: 681842"] Amplifiers need 3 things to operate 1) power 2) signal 3) trigger (remote turn on) Power is as easy as running a fused power wire from the battery to the amp, then a ground to complete the circuit. Remote wire is a power source that turns on and off with the car. Since the amp is wired directly to the battery it would always be on the remote wire turns the amp on and off with the car. Aftermarket HU's have a wire coming out of the back for this but your stock one does not however this can also be accomplished by tapping one of the cars fuses and running a wire from there. Signal- (Big part of integrating) This is the hard part of getting an amp to run without an aftermarket HU. You have to run RCA's from the music source (HU) to the amplifier. This is where the sound comes from. Stock HU's don't come with RCA outs on the back of them. So now you have to find a way to convert the signal coming through your speaker wire into an RCA cable in order to get it to the amp. Now most amps come with speaker wire (high level) inputs but the amp needs a more powerful signal if you want to work up to its ability. The signal needs to have a level of power with it . For the sake of explaining it to you we will say 5 volts on average. The power coming from speaker wire is less than 1 volt. An aftermarket HU will put out anywhere from 2 volts- 8 volts depending on the HU. The cheaper the HU the less the voltage it is going to put out. A DSP allows you to run speaker wire into it and then it converts it to RCA signal and then boosts the voltage to RCA's and a whole other host of things as well. I think hispls said it the best, it allows you to nerd out on your sound system Most of them come with software and allow you to hook a laptop up to your system and tune it from there. This is the one I went with, not saying its the best its just the one that suited my needs the best. Take a look at it and its options if you want a better understanding of DSP's [URL]https://rockfordfosgate.com/products/details/3sixty3/[/URL] [/QUOTE]
