i have a 4 channel amp that will run my 2 front speakers (new components) and a sub. what do i need to connec the rcas to my stock head unit? i know i might need two adapters ( dont know what they are called) for 2 sets of rcas. which speakers do i run for the sub also?

 

You can do alot of things actually. You can get 2 Line level converters like you said. Or you can get one and get rca splitters that split the rca from 2 to 4. You can get one loc that have 2 outputs. Its really up to you how you want to do it.

 

They make 4-channel LOC's too

 

what speakers do i run the sub rca from on the stocker? im guessing just the rear? or can i splice both loc to the front speaker wires form the stock head unit?

my amp has a speaker level input on it. it has 4 sets of wires that all connect into a telephine like plug. would this be adequate to use instead of an loc?

 

Yeah use the rears. And yes you can use the high level inputs. All that is, is a LOC inside of the amp. That will work just fine.

 

Ahh yes I totally forgot about high level inputs... I would actually do that if you can.

 

i will be leaving the rear speakers to be powered by the stock head unit.... im goin to use the high level input for the front speakers and sub... everything seem ok?

when you say high level input... is that filtering sound for only high level speakers or is this just the name its given?

 

It's called high level ouput because it's using the already amplified speaker outputs off the headunit. It's a higher voltage lower impedence ouput. Low-level outputs are RCA's, they're lower voltage (generally) and higher impdence ouputs. It won't filter out any frequencies either way.

Why are you only amplifying the fronts? Why don't you bridge the amp and run all 4 interiors off it. You'll just lose fader. If anything most people amp the rears cuz they're further away. rears cuz they're further away.

 

i have already installed a really nice set of components in the front and they easily take all the power the head unit can give. i will bridge the rears into the amp in time but for the time being im more concerned with the front doors and a lil more bass. im doing this all piece by piece so for right now this is where im at..

thanks for the help!

ill post some pics once the amp is installed!

 

run a high pass filter off the back two speakers. run ur remote to ur fuse box preferrably to a stereo fuse. run ur ground and power cables and enjoy nice sounding music in about 30-45 mins.
