Q: What size speaker box do i need for my 2008 chevy silverado?
I just bought a 2008 Silverado Ext cab and wondered what size i would need to make a custom box to fit two 12" subs

A: Whatever fits under the back seat. 12" subs need about 1-1.25 cu ft of air space depending on if the box is going to be ported or not. The shape of the box is not important as long as it has the required air space so calculate the dimensions you have to work with under the seat and build the box to fit making sure the inside dimension will give you the required amount of air space for each sub.

Q: what are chevy dealers bottom dollar for a 2008 Chevy Silverado Z71?
I'm looking to buy a new 2008 Silverado Z71, I'm wondering how low dealers will really go on price. Anyone have an ideas? Cheapest price

A: Its really tought to say. Dealerships that sell more can sell for less. You could probably get $8,000 of MSRP but they won't give it up easily and many of them won't do it at all. This will really depend on where you live too. In large metro areas the dealers sell more cars and usually sell them cheaper. Outside of these areas you might not get more than 4000-5000 of MSRP or less.

Q: turbocharger or supercharger for a 2008 chevy silverado?
i know in racing games, you vehicles usally have one or the other, but not both, so i wasn't sure if you can only put one type on a vehicle and if so, which would (or if either, should) go on the 08' chevy silverado?

A: A supercharger will give you immediate horsepower and torque. You can get one that fits under the hood, McCulloch, etc. A Mc Culloch or one like that, will work with the compression ratio your engine has. A turbo has a lag when you first get in the throttle. You can install both but it would be a nightmare. What I like about the blower (supercharger) is if I have to let off the throttle on a hill, it picks up quick whe I get back inthe throttle (torque).

When I go to GMs website and try to pick options it doesn't seem to be offered. But when I look at my local dealers inventory they list some as having manual trans. Any help please!

A: On the 2008 model silverados 1500,2500HD and the 3500HD the standard trans is a four speed hydra-matic with overdrive and tow-haul mode.The factory does not offer a manual trans as a option.Best of luck.

Q: How Do I Tighten The Spare Tire on a 2008 Chevy Silverado?
Ok well the spare tire on the underside of the truck bed is kinda wobbly and I wanted to tighten it up but I cant see anyway to even get it off even if i wanted too, heres the link to the best pic i could find that looks like it, http://cdn-www.expertvillage.com/showImage.aspx?site=21&fn=flat-tire-spare.jpg any answers?

A: Find your jack kit, there should be 2 extension rods with square ends on them. You'll find a small pop off plate on the bumper, assemble the extension rods and stick them in the opening (you can look from underneath to see where the rod needs to hit). Once you're locked on use the supplied tool to turn the rods...this lowers or raises the spare tire. This is common on most GM trucks/SUVS from 06 and up. My concern would be why it's loose. If you've never used the spare the system should have remained in it's factory position. It's possible your truck slipped through a lazy GM employee who did not ensure the spare tire winch system was at spec. If you secure the tire and it loosens again in the near future chances are the little winch is no good. I'd imagine you're still under warranty, if this occurs take it in and have it replaced. Hope this helps!

Q: My check engine light came on in my 2008 chevy silverado?
I ran a check and got these codes: P0036 and P0141. What do I need to do? Is it something I should take care of a.s.a.p? How much do you think it would cost to repair if necessary? Need help!! Lol! The problem is I installed an exhaust and intake. Do you think that would matter?

Q: i want to buy the new 2008 Chevy Silverado 1500 WT any pros or cons?
i have done alot of resarch, but i would like more users opinions, so tell me what u think/ suggest oh and just on another note...i have to get a truck for band equpt. i have a lot of hauling to do. (i also have a car which will be used for normal driving)

Q: i drive a 2008 chevy silverado. i want to upgrade my (4) door speakers?
its an extended cab and both my front and back speakers are 6 1/2. im not planning on changing my stereo so would it matter how many watts my aftermarket one will be. and would there be any ploblem with the way they fit all i want to do is change the speakers they are not bose i dont plan on doing a complete system change

A: My rec to you is to wait until you do a complete system before you choose to replace one part of your system, here is why, GM/Bose has spent millions in r and d of the speakers and placement, along with the sound system, you are talking about arbitrary replacement of speakers, without really planning the overall system-don't do it, wait until you can change the whole system-just my opinion, however,

Q: Why is the 2008 Chevy Silverado Z-71 package required to get the 18" wheel option?
If I have just a Silverado 4x4 (i.e. not Z-71) will the 18" wheels not work?

Q: Will installing an amp in my 2008 Chevy Silverado void my warranty?


A: Most warranties are void when adding items which are not installed by the dealer. With todays electrical nightmares in new cars, I would strongly recommend that you have what ever you want installed placed there by the dealer so they are responsible. Ask lots of questions by the dealer too, They will be the first ones to void you and make money. Good luck.
