Aftermarket Sub
Okay guys, I have read pretty much every thread in this forum (man you people talk a lot ... lol) and I think I have it down. I would just like to confirm that if I install my Infintiy Basslink sub in a stock 07 Laredo with the kiddie radio, I should have no problem. I will be running the sub through the universal interface using only the rear door speakers. I know what you're thinking and yes I will be upgrading at a later date (hopefully a Alpine HU).

Re: Aftermarket Sub
I am confused. What amp are you using? and your tying into the speaker wires from the rear doors?

1st suggestion is use the front door speakers to tie into as you would do with the
OEM Kicker sub. You can use the same wiring path for your power line as well.

Here is a link to a guide using the OEM kicker but process should be similar :

Re: Aftermarket Sub
Thanks for the link, very informative, however I just read the install pdf and his commentary and neither places explain or elude to why it is better to use the front door speakers over the rear. I'm wondering if its just the way the factory harness was made. The install, in my uneducated mind, would be a lot less involved using the rear door speakers, but if there is an sound advantage to using the front, then thats what I'll do. I'm using the Infinity basslink sub which, much like the kicker system, is an all-in-one unit. just tried to post a pic, but the site won't let me, so here's the link.

Re: Aftermarket Sub
The reason you want to use the front door speakers is that they are crossed over in the OEM cabin amp to 90Hz, max.

This is where the system gets is bass imaging, whether Kicker, or BA.

The rears are filtered to 120Hz.

With the rears as your signal source, you can get a "muddy" bass signal. The front doors are a better bet.

If you want a direct subwoofer output from the amp, you can try connecting to pins 5+ and 13-. These are: GY/BN & DG/BN for all but the SRT8 model. On the SRT, you will want pins 4+ & 5-. These are: DG/YL & GY/TN.

Hook to these wires with a volt meter. With the radio on and the voltmeter set at DC volts, you should get a 6 volt output, from either of these pairs of wires, depending on your trim level. If you get 6 volts (+/- .5 volts), then you are getting a bass signal from the amp and you can use those wires for a clean bass signal.

Hope this helps.
