which alpine speakers? what kind of amps? 100watts peak? rms?  thought about using a multichannel amp, like 5 channels or so? what kind of 10" sub? what are your goals for the system, sound quality or SPL? kind of need a little more detail on the stuff. if everything is done right it'll be better then stock. i cant say leaving the stock head unit is a good idea if your changing everything else. thats almost always the first thing i change. but if cost is the biggest problem for that, just wait till you can afford it and it'll sound even better. and you will love your truck just that much more.

Copper, I am in the middle of a similar upgrade with my HD.  

 

I have replaced all 4 door speakers (Alpine front, Fosgate rear).

 

I have a Fosgate punch amp to run the sub.

 

The sub box dimensions are

 

Measurements are:

H = 7.5" (front) & 6.5" (rear)

W = 13.5

D = 15"

 

It holds a 10" and has .5cu ft

 

Here is a pic

I am changing the HU but the 2002 Alpines are not in yet so I am patiently waiting.

 

You HAVE to change out the HU!!!!  It will sound worse with aftermarket speakers!  I was told this by my local shop and they were right!  Your wasting your money if you don't

Offroadr -  Where are you mounting the amp?  I'm contemplating adding a sub to my ext. cab.  I already have a fairly large Alpine amp, but haven't decided on location that's out of the way.  I fold the rear seat up a lot during the winter so that I can hold my ice fishing equip without getting the seats wet and full of snow, so I'd like to be able to put it someplace that's out of the way and will have good circulation.

Firetiger, I am mounted mine behind the sub box it is completely out of the way.  But understand that I have have a crew cab and the way the seats fold are completely different than an ext cab.  (Actually I think the ext cab seats have a better design that give you more room.

on the rear wall behind the rear bench works fine, i can still fold up the bench seat in my K2500. it rubs, but still can be done.  as long as you arent pushing the amp like there is no tomorrow your amp should be fine. if you get worried. add some fans. (good amps shouldnt even break a sweat when not trying to reach crazy spl)

      New or used

      By Chuck FB · Posted

      Certainly as the new model year comes along and that may mean a new refreshed model such as for example the upcoming 2027 half tons and lets just say for arguments sake that current year trucks are in decent supply on the new lot and its not guaranteed but some years and depending on the current economic state that buyers may turn their nose up at the so called old stock/old model and want the "new new" shiny object. When those stars align and in this case GM corporate puts out a great discount on what is becoming the old stock as well as dealers willing to deal to get that inventory off the lot, that's when it would be easier to deal as long as, as it was pointed out that your willing to take what is there for choice of inventory in an area that makes sense to you shopping wise. What you don't get deals on or typically so is the incoming new toy in the showroom, that is where if they don't have much inventory of the new model year and customers that are willing to pay to beat the Joneses and will pay top dollar for it just because. Also sometimes there is that vehicle that few are interested in for whatever reason in how its equipped that becomes two years old and they really want to get rid of that vehicle. New in all cases and warranty the same typically although plan on changing that battery out on the older used one, lot rot of batteries with todays vehicles that draw power constantly.    I too was just too leery about buying a newer used truck as I know how all too many seem to treat their vehicle maintenance wise and up here in Canada there wasn't the used market to choose from like one would assume because of all the bull crap going on with under a year old trucks and under certain mileage being bought up by USA brokers and being hauled/driven south to be sold in the sates so the used price was too demanding here. Also a certain insurance coverage I wanted was only available on a new truck at time of purchase and not even a so called new demo on a lot could have that no depreciation loss coverage. I made the best deal I could on a truck I personally chose for options on an order so they knew it was most likely sold before it ever hit their lot so no lot interest charges for the dealer to swallow. I also wanted a new vehicle so that I could plaster the crap out of it underneath with fluid film and see if that will help slow down the rust issues we have here due to the crap they spread on the winter roads.

      2026 Silverado 2500 Surround Vision Recording?

      Sure...but there is no "update" to be had.  GM has not issued any support for this.

      You mean it's not supported yet in the trucks. The hardware is certainly there. The software just needs updated.

      2027 Chevrolet Silverado: Official Discussion

      By asilverblazer · Posted

      Is the carbon pro bed still a thing? I figured it was one of those things that quietly disappeared from low take rate.   I thought Chevrolet tried adding it too...   Minimal.   Despite all the 'all new' versions since GMT-800, lots of parts still swap from generation to generation.   I've seen a bunch of GMT-800s with a K2 rear bumper on them.

      We still haven't seen the GMC's. I expect the Chevys to more orr less match the Fords, but with no all aluminum body and simple SBC, be significantly more affordable. I'm hoping GMC offers the 6.7 engine and lays it all out on the line. My main question? More premium GMC's already use composite leads out back. Does Chevy get any? What other frame/suspension changes?
