new audio system - harness question

[bigpappa318]

Hi all,

I have an 09 Tahoe LS, non bose stock. I'm slowly putting together a decent sound system, so far I've ordered the following from Amazon.

- Pioneer AVH-P4400BH 2-DIN Multimedia DVD Receiver
- Complete Sirius Radio System for Satellite Ready PIONEER Receivers CD-SB10 + SCC1
- Metra Axxess ASWC Universal Steering Wheel Control Interface (Black)
- Metra 72-4568 Speaker Harness for Select GM Vehicles
- Metra 95-3305 Double DIN Installation Dash Kit for 2006-up Chevrolet Vehicles
- 2 of Polk Audio DB6501 6.5-Inch 2-Way Component System (Pair, Silver)


I'm not certain, do I need any additional harnesses or cables to do the initial install of the head unit and components, wanting to maintain steering wheel controls and sirius sat radio?

I'm going to see if I like how the components sounds off of the head unit power to determine which type of amp to buy. Planning on a single 10" under bench seat box, so not sure if I need a 5 channel amp to drive the whole system or a single channel amp to drive the sub.

Thanks!

Looks like you ordered everything you need except for the actual radio harness. I have the GMOS-LAN-012

http://metraonline.com/part/GMOS-LAN-012 this one has a plug and play harness for aswc.

http://metraonline.com/part/LC-GMRC-LAN-01 this one is much cheaper.. but you will need to wire aswc yourself.

Ugh. Thanks, I just ordered the GMOS-LAN-012....

Anyone have any suggestions tips on installing components? Is there a stock crossover that needs to be removed or can I tap in to the existing wires in the door?

Thanks! First time with an audio install....

http://www.scosche.com/car-audio/product/2028 these might help. door speakers are full range. you will need to run some wires from the xover in your new comp set to the pillars for the tweets. the door speaker and tweet wires are just paralleled.

Thanks. I bought the sirius kit for pioneers. Can I tap in to the stock xm antenna or will I need to install the add on sirius antenna?
