yes, read the sticky at the top for more info on how to do it. Basically stock radio to a Line Output Converter/signal processor to amp to speakers.

You can also search for a DIY I did a while back on how to add a basic 4 channel LOC to your stock radio. That should help.

 

I'd start with the main audio install guide sticky. All the pinouts for the amp connectors are there. If you have the base stereo, you can get away with a cheap LOC, but if you're dealing with the bose amp, you're going to need something like a JL cleansweep, audiocontrol LC6, or Rockford fosgate 3sixty to boost the low level signals to something useful. Unless you want to tap the speaker level outputs of the bose amp, with it's gross EQ curve.

I don't see how we can continue to be this nice while answering these topics twice a week.

 

Yes it is very simple.
Get a amp, box, and RCA converter...
I got a amp that fits between the back seats so the AC in the car can cool it in the summer time. The trunk gets really hot from the exhaust in the summer time.
I got the sub box off of eBay and it fits and looks great.
All i did was wire the rear speakers to a RCA converter and plugged it into the amp for the signal. Then run your ground wire, 12v positive wire with fuse to the battery and a remote wire for it to come on and off when you want.
The remote wire i ran to the fuse wire of the ignition power for it to turn on when they key is turned.
But with kids and certain passengers in the car I ran a switch so i can turn the amp on or off at any time. Some people do want to hear the subs at all times.

I put some hardware on the box to the frame of the car so it can not be pulled out of the trunk unless you get inside the car. So driving crazy makes it stay nice and cozy without flying around in the trunk.

Here are some pics easy to do.
The cover that is between the seats was cut so i can cover the amp so no one can see the amp and want to steel it. I had no room in the trunk either for the amp.

Hope this helps. SOunds great with the stock deck and its amazingly really loud. 2- 10 inch subs sound really nice for the space in the trunk.

Interesting way to secure the box down. But effective.

But I'm curious as to how the JL amp mounts? It would appear that it is screwed to the back of the box, but your eye bolts are there and appear to be in the way.

 

The JL amp actually fits nicely in the opening.
It slid down at the bottom into place. I cut a piece of wood and slid the amp down into place first. Then i put 2 screws on the top portion of the amp.

So it looks flush but the amp is about 1 inch deeper downward into the car opening.

The eye bolts on the box was key after someone tried to steel it and could not get it out.
I used squared headed screws as well for the speakers to mount in the box. They tired to unscrew the speakers out but had no luck. You have to have a square headed bit instead of a generic phillips head screwdriver.

 

Sounds like the crook had a square head.

 

No thank goodness they didnt have a square head.
They tried but just stripped the screws.
All is well and i still have my stuff.

 

People cant even read a forum but they want to add subs and amps to their car.

NICE.

 

why did you cut up your pass through panel? you know you just could have unscrewed that back piece?

 

When I unscrewed the back part of the pass through panel the latch was on that piece that was unscrewed.
So i cut around the latch part so i can still close it and lock if need be.

 

you can unscrew the latch too.
