I just put my a new stereo into my 00 GS4.

Sub: JL Audio 10W7 with the JL 500 W amp
Diamond S600S in the front and 5" Diamond coax in rear Powered w/ a 4 channel Alpine V12

I ran the speakers to High/Low converters then to the Amp.

Questions...

Is the factory amp in the head unit? In the current configuration, the fronts seem to be already crossed over at about 100HZ. If this is true, any recommended wiring to bypass the crossover?

How are the super systems being wired - I want to keep factory head unit.

Once I get this right - I'll post some pictures and lessons learned

Thanks

 

I'm curious, why do you want to keep the stock HU?

 

Im putting a system in my ls400 and I plan to keep the stock HU because it has a cleaner look, most of the aftermarket stuff out there is so flashey and does not fit in with the elegance of the car.

BTW, I see that you are using a line out converter (line level converter), but where did you find your remote wire?

 

I have the Nav system and the head unit has controls thru the head unit.


Response to the other question...
Which remote wire? To power the amps? I used the ignition. The draw back is the amps are on the whole time the car is running.

 

If you want more control over when your amp(s) are on while the car is running you could install a togle switch on the remote line.

 

I was thinkin of hooking it to the ignition or the fuse for the radio using an "add-a-circuit" kit as said in another thread. Any advantages/disadvantages for either way? Yeh i also plan on throwing in a switch on the line for when my parents drive the car or whatever lol..

 

ok, so are looking for a power source to start your amp?

 

Sound gate makes a product that works like a relay. I think the head unit trigger is only 5 volts and an after market amp needs 12V. Check out the sound gate site

 

Yeah a wire to tap in and use as remote

 

I'm not sure about the color code on your car, but there is remote wire connected to your HU, the wire is blue on most after market HU. If you check the factory wireing you will see a color pattern of purple and white purple which will follow with green/white green, gray/WG, blue/WB and a few other colors that make up the speaker connection. The power group will have black(ground), yellow(power), red(backlight power), and the remote will more than likely be orange. : Hope this helps you out.
