Just picked up a 2006 GT with the Shaker 500 system.
I already have 2 Infinity reference subs in a box.
Soon I'll be getting an amp.
Just wondering how you guys tapped off the audio system to get the input to the amp?
Is is ok to tap off the 5x7 in the rear deck?


Thanks

 

That would be the easiest way using a line out converter on the 5x7's in the rear. I believe there is no crossover on the rear speakers and the amp only powers the eights in the doors. BUT if you are ever planning on changing ur radio I would do it behind the factory deck so u will already have the rca's back there and u will have a functional sub control from your radio when u change the deck.

 

yeah the line out converter is going to be the easiest

 

No you can not connect to the 5x7's in the back, please do not waste your time trying! I have been there and done that, and it is very frustrating. The only way to hook up a line-converter is to hook it up to the voice coils for both left and right amps leading to the subs in the doors. The problem is there isn't a low enough frequency going to the 5x7's. If you plan to keep your factory stereo and connect an amp, you will need an add-a-circuit fuse tap to power the remote wire. Plug the add a tap into the fuse slot that is not being used on the same row as the windshield wipers, and use a 10amp fuse for the remote wire, and a 5amp fuse for the accessory slot (that's the only way to get it to come on when you turn the car on). After that you have to connect speaker wire to the wires that come out of the factory amps which are located just above the driver side kisk panel. I recommend removing the connection plugs from the amp in order to tap into the wires more easily (I was limited on my toolset, and was only able to remove the one on the left, it is taped to the inside with electrical tape, and is easy to pull off and tape back. The right amp's connection bundle is behind the left one and is much harder to remove, therefore making it incredibly hard to peel back the wire plastic so that you can tap into it, especially in such a cramped space). On the left amp, tap into voice coil #1's positive and negative wires using any size speaker wire (I recommend a 20 or so, the smaller it is the easier it will be to wrap around the exposed wire), and then do the same for voice coil #1 on the right amp. Follow the directions for the line-out converter (I recommend a scosche line-out converter from Crutchfield, because they also provide support for it) and you should now have bass coming to your subs. It isn't as easy as you think, but it is worth it if you are looking to add a little bass but keep you 6 disc MP3 player.

 

I plan on adding alot of bass with my NEW 06 KENWOOD KAC-8152D MONO BLOCK AMP 1100W (ebay)
powering 2 12" infinity reference subs.

Do I need a line out converter?
The amp has line in and speaker level inputs.

You shouldn't need a line level converter, but you still have to hook up behind the factory amps that go to the 8" subs, because the rear speakers do not emit any low freq signals. I believe for the left voice coil it is the blue and yellow wire that is positive with the one next to it being negative. While on the right voice coil it is the light gren and orange that is positive with the light green and purple one being negative. I'll get more specifics and post it later on today.

 

Voice coil #1 Negative: Light Green with ReddishOrange stripe. Positive: Light Green and Purple stripe.
Voice Coil#2 Negative: Dark Green with White stripe. Positive: Blue with Yellow stripe

 

Thanks

I'll give it a try in a week or 2, since I'm working again.
