Does anyone know if you can install subwoofers with an amp to a factory installed Bose Sound System in an 08 Chevy Silverado?

If I read correctly, you want to add an amplifier to your factory Bose system.

If so, may I recommend the PAC OEM-2 Line-out Converter:

I have this installed into my Civic and it works like a charm. You'll have to get under your dash and connect these wires to the Harness, but it'll give you RCA outputs that you can use to add an extra amplifier. All while retaining the functionality of your Bose system.

I bought mines on Ebay for about 17 dollars.

I think the hardest part is getting to the wires. When you actually get to the wires, just look at the diagrams and connect the appropriate wire. I will include a wiring diagram for your stock wiring harness, and a instruction sheet should come with the OEM-2 that lets you know what each wire on the OEM-2 is for. (the OEM-2 Wiring can also be found here: http://www.pac-audio.com/PACProductD...ons_061107.pdf)

I'm not really sure what the C1500 part means, but it was the closest thing I could find. It's up to you to verify.

Other notes:

You don't have to connect all the wires. I only connected my speaker wires to the OEM-2 and called it a day. Maybe you'll want to include the remote turn on wire as well, but that's about it. Connect the OEM-2 speaker wires to the stock harness, find a place to tuck the OEM-2, connect the new amplifier to the rca outputs, and enjoy.

If you are going to take the lazy way out, just make sure the pre-stripped wires are properly shielded (I used masking tape) to prevent shorts. Granted it won't blow your speakers, but failure to do so would mean opening everything back up and going back in as your speakers would either fail to work, or work horribly.

@ChevyHD,
That system has a factory amp, you do not have a normal radio. There is a specific harness for your install(available at your local car audio supplier). If you are not handy splicing into a wire harness then you may also want your local shop to do the work for you, as they offer a warranty should any problems arise. I DO NOT recommend taking it to "Best Buy" as they do not care about quality but quantity in other words if it does not work OH well.

I have seen systems that people tried to do this install on, that did not know about the factory amp and they spliced the harness to bits.
