2009 Sierra Subwoofer Options

jcoan_11 · December 31, 2009

I have an '09 Sierra extended cab without the Bose system, and I am looking to install an aftermarket sub under the rear seat. There isn't much room back there, and I really don't want to shell out the nearly $800 for a JL Stealthbox. My ideal setup would be a single 10" in a ported box, but most likely will have to go sealed with the area I am working with. I would also like to stay in the JL family and put in one of their 10W3v3's. Anybody have any recommendations/advice? Also, any pics of your setups would be appreciated. Thanks.

Has anyone had one of these?

It's a box I keep seeing on ebay. It's got 6in mounting depth for your subs. 12's or you can buy their 10in box. Air Space: 0.60 Cubic Feet Per Sub.

It's $109 w/Free shipping.

Subthump's 12in box requires you use a sub that has less than 4.5in mounting depth and runs $187 Shipped.

Subthmps 10in box runs $177 Shipped!

I know alot of folks on this site prefer and recommend SubThump but are they really worth an extra 70 to 80 bucks?

I have an 08 Ext Cab and put in a Subthump box with a single JL 10W0V2. I am driving it with an Alpine amp. I have been real happy with it. I don't listen to much music that thumps all the time, but it kicks pretty good.

Subscribing to this thread. This is an upgrade I would like to do this spring and am interested in what others have found. Although I would like to keep the factory head unit, my plans are to add a sub, replace all factory speakers, and put in a couple amps as needed. I would like to keep the budget under a grand but once I start spending it's hard to stop.

This seems like a good low cost option. I am looking around now to see what subs I can find to work with these dimensions and air space. Certainly worth considering, thanks for the link.

I agree. I have one of his boxes in my Crew Cab and WOW it's awesome. If you ask him he will add a AMP Rack in between the subs so you don't have to mount the AMP on the Back wall or under a Seat. IT ROCKS!!!!!

Which subs did you guys have put in? I talked to Rodney and I am thinking about having him do a single 10" JL W3v3.

Is Rodney74 a user here on this forum?

I HAVE ONE OF RODNEYS BOXES AND LOVE IT. I'M RUNNING TWO JL 10W0V2'S IN IT AND THEY FIT PERFECTLY UNDER THE REAR SEAT. IT'S A SOLID HEAVY BOX FOR THE MONEY.

Who is RODNEY?

^^^Not a bad price for a complete sub unit. Even with shipping I'd be right around $600. Since that includes the box, subs, amp, and some wire not a bad deal at all. I'll have to check with some local shops to see if they can be competative.

Jason,

Where did you mount your amp ? Can you post additional pics of your install ? I am interested in seeing how you have everything setup. I am currently researching equipment to do a complete change out in my 08 Silverado Crew... Dual amps powering twin 10's in a down firing setup, components up front, new deck etc... the whole shebang...
