i just bought a 12 inch powered sub and want to install myself because i do not trust anyone with my car. Any DIY posts or suggestions from people who have installed these in their car would help. Do i have to remove anything major like my NAV unit? Any input would help me out.

 

Anything???

Could use the help.

 

there are a couple threads here that go into pretty good detail, basically you just need to run power to the back, get a hi/lo converter and tap into the factory amp wiring which is in the trunk on the passenger side, i would probably remove the factory sub in the rear deck.

 

started to wire my is it's kinda a pain but didn't help it's 18 degrees outside right now so I'm holding off but this video helped me check it out good luck

 

Thanks for the information.

 

you don't need to remove the radio or nav. Amp is the back. If u didn't find the RCA output wires, let me know. i will take a pic of my setup and post it here.

 

GS has different setup than IS. You are not going to find that subwoofer connection in IS350 back ceiling(Pioneer system). You gotta get the connection from Factory Amp.

 

agreed.. everything can be tapped into the factory amp... from remote wires to rcas

 

I had time to drop off at my local stereo shop. They did work on my last vehicle and I was impressed. I was going to try it myself because I enjoy doing the work on my car. I only had to pay $40 for the install and very happy with the bass I have now. I will have to tweak the settings a bit for my taste though. If anyone is wanting to add some good bass this is what I got. Bought it from amazon for $188.00 shipped. Rockford Fosgate punch P300-12 with 8 gauge wire. I'll post pics tomorrow when I clean up the car.

 

Don't buy square boxes bro. There is a guy who make custom box for IS. They fit perfect and you will have good bass and more space in the trunk. I will upload pics tmw and also for RCA connections.
I bought Pioneer GM-D9601 2400 Watt Mono with PIONEER TS-W3002D4 Champion Series PRO 12" 3500W.
I don't need remote wire for this amp. RCA connection turns on and off the amp. setup is pretty easy.

I have same enclosure with 1 sub hole.

 

Here is mine.

Nice and good song as well.

 

Nothing fancy but will work for me.

 

Here is the remote for the sub. For now I velcro it to the carpet for easy access.

 

Here is where 2IS owners post their custom installs. Mine is at the bottom of page 31.
