Is it possible to hook up some aftermarket amps and speakers to the stock headunit in order to keep the steering wheel controls? Also, could you adjust the output of your amps so that the stock headunit will give more volume? Some professional help would be appreciated.

 

yes, just insert LOCs between stock HU and aftermarket amp....

doc

 

mine is aftermarket everything with stock HU.the volume can be crank up to 30 (i don't know what was before,never try) it loud enough and very clear.

 

What are LOCs... Maybe that set up can save me some money on getting an aftermarket HU... or just get better subs and a more power full amp...

 

problem with stock HU is lack of ability to tweak sound staging and settings *effectively*. LOC = line output coverters.

You'll need something like this:
