Gmt-900 Subs In Ext. Cab

Northern Sierra · October 27, 2009

I'm looking to install some subs in my new sierra and was wondering what people were doing in the new extended cabs. Going from a Tahoe where I had ample room I was able to put two 12" Rockford P2's. I know im going to have to go with something a little differen because of space. please post any sugustions or photos that might be of help.

Thanks

Chris

i just got my system installed and i am very impressed. i wanted more a sq sound versus the spl. i went with a image dynamics idq10 v.3. i bought it on ebay with the box for around 250. if needed it can really shake the mirrors but i went with it because it really sounds very smooth. you wonder where its coming from. very happy overall.

I don't know if your under seat area is similar to my ext cab Silverado. 2009. I found a few boxes on ebay that hold 12's but one of the folks posting on my thread said to check with subthump.com that they had really well built sub boxes..

other than that try one of the ebay boxes. I had one in a previous truck and it rocked!

im going with a 10" jlw1v2 in my 08 ext cab sierra. going with the subthump box under the back seat, but am trying to figure out if i need to get charcoal carpet or blac....both colors look differnet in multiple pics. i have the ebony interior so im guessing black?

they make a box for 2 12s as well, which is what i was orginally gonna go with, but i figured id go with a good quality sub that will give me everything i need and isnt too crazy loud.

Sierrawhite - how does the JL W1v2 sound? I was thinking of trying to install a W3v3, but wanted to know how the W1 sounded in the subthump box.
