    Default 2009 silverado ext cab sub-box?

    Anyone put a box in their 09 yet? I looked under my rear seats and it doesnt look like there is much room for anything... esp the way the room is under there.

    I looked into the JL audio stealth box anyone have this setup?

    looks like a good box. I think one good 10" and a mono amp would work good.

    I have a 07 GMC Sierra 2500 HD and just put the stealthbox containing 2 10W3's in saturday. I used a JL HD750/1 amp with the 4 gauge JL amp kit, and I used the JL remote which gives like 7.5 volts to give the amp a better signal since I kept the factory HU. I had very high expectations so maybe it's just me but I am NOT pleased with the results, it sounds good don't get me wrong but, the system cost me nearly $2000, and I know I have put together systems in the past for alot less money that sounded just as good. Like I said, maybe I have unreal expectations but I let a good friend listen to it and he had the same question, which is "is this really what a $2000 system should sound like?". I actually installed his system in a 2004 Dodge cc and he had around $500 total in it and it nearly sounded the same. Granted the JL system is cleaner sounding and hits a little harder but I was expecting there to be a significant difference. Let me know if this helps or if you find out anything else, if the company doesnt take the stealthbox back then I may have one for sale. I was thinking of building a custo box to house 2 8w7's but I think I am going in another direction away from JL.

    I also think that may have bowex for your body style. I'm going with subthump because i want the box under my back seat.
