Hows it going all? I just bought a 2002 Silverado with ext cab. I dont believe it has the bose system. As far as I can see its just the AM, FM,  CD.   I want to add a sub but, keep the factory deck. Im looking for ideas on it. I have seen crutchfields sub add on but, it goes across the whole back and I dont want that. The jack is located under the passenger side back seat. I dont want that to be hard to get to if I need it. Im thinking maybe Kicker solo baric since they only need tiny boxes. Ive done stereos , amps, subs etc so Im not a newbie. I just need simple ideas of things you may have done or seen. Im not looking for expensive elaborate stuff. The sound is what matters. I also would like to know what converter I will need to keep the factory deck and add the amp for the subs. I may add like 2 or 3 amps or one big one that can run all speakers and the sub also I havent decided yet. If you know which converter will allow me to expand to this I would appreciate that.  I want to start with the sub because thats the most glaring deficiency. After I see how that sounds I will make decisions on the rest. I have an amp I can use to try the subs but im open to suggestions. Thanks Boomer

An mecp certified friend of mine made a fiberglass enclosure out of the rear seat of a similar truck.  It is a bench, right?  Anyway, he carved the foam out of a section of the seat and layed fiberglass in the hollowed out area.  Just make sure, if the depth of the seat allows, to flush mount the sub.  Just make sure that the sub doesn't strike the floor or anything while playing.  He said that the seat was still usable and it was barely noticable that it was modified.  I plan on doing the same thing to my dakota this summer.  Then if the rear seat folds up you can mount the amps underneath nice and neat.

I'm sorry.  I just realized that I didn't specify that it was mounted in the UNDERSIDE of the seat facing the floor.  I just reread what I wrote and things didn't look clear.

To keep it simple, nail down the sub choice first, that will tell you what amp to find to power it and how to wire it in. You are corrrect about choosing a sub that needs a small airspace, if you want a sub that will hand the Kicker it's derriere, find yourself an Eclipse aluminum driver, custom build the box for the allocated airspace of .5cu.ft (net volume) - 1.25 cuft. (gross volume), the larger this box can be the more authority the sub will have. If you choose the right amp it may have the necessary hi - lo adaptor built in. If you want to do a major expansion either now or down the road and retain the factory head, have a look at the scosche FAI-3, it is a 4 channel adaptor with indipendent gain controls. If you choose the right amp or amps you will not need any further adaptors. If you need more info on that, post up and someone will answer it for you.

NaughtyLMnky Ty for the reply. Im not crazy about cutting foam out of the seat. I prefer not to mess with the integrity of the vehicle too much but, it does sound cool. It would retain the floor space. Im figuring when you sit in the seat of your friends truck you can feel that there is very little padding left right? Just curious but, doubtful I would go that route.

  forbidden , What size sub were you speaking of? Just one or two? That seems like a nice small box.  I know the solo baric is supposed to be like having a pair of the normal subs. I have two 10" kickers in my car and the bass is good.  As far as the amp goes I am assuming your talking about an amp that excepts hi level inputs?   I guess since the head only has 4 outputs I am going to have to run a couple of the factory speakers off the amp as well initially if I am gonna steal a set of its outputs. I have a feeling the factory speakers wont stay in long. I doubt they are gonna give the good quality sound I am looking for but, that shouldnt be a problem.  Thanks for your advice.  Im mainly hoping for some good ideas on how to do the sub while keeping my desires in my mind that I listed in the opening post.  Thanks alot guys

Boomer, almost but not quite right, One aluminum driver (10") will probably be way more than enough output for you, if you want 2, all the power to you. We built his box to sit under the center part of the back seat and come to the back of the front seat. The sub we used for him was an MB Quart premium 10", the box volume net was .775 cu.ft. It fit like a glove and sounds great. I wish he would have gone aluminum though, it would have embarrassed the Quart.

Now for the amp issue, all you need to do is connect the high level input wires from the amp to the speaker wires, you do not disconnect the speaker wires from the head to the speakers. All the high level input wires leads are doing is "sampling" the signal to convert it to a signal that can be amplified. It's a pretty easy task actually.

Nail down the sub for sure first and then we can get you started on which amp and how and where to put that box in.

I didn't get to sit on that seat myself but I was told it was still pretty comfortable.  I would also assume that he left as big of a layer of foam in there as possible but I would think you could notice the difference before and after.  I was also thinking that with a truck you usually don't utilize the back seat for passengers all too often.  At least I don't.  I know it probably wouldn't want to be something I would want to sit on for a long trip but those occurances would be few and far between. 

All of these are just my personal assumptions.  It probably really relies on how much you have to gut the inside of the seat. 

I am usually one for maintaining the integrity of the vehicles interior also but I am finding it harder and harder to find space for a decent install in trucks.  This the first truck I owned myself.

Thanks for your replies and time. It would be cool if you could mount to the bottom of the seat without cutting any foam but, Im not sure how you would do the enclosure. That would probably hang so low that you may as well just put it on the floor. 

forbidden I dont want to extend all the way to the front seat as that would block passenger leg room.  Im trying to keep in mind how small of a box a certain woofer can have while making a decision. You seem familiar with the eclipse alum cone. What would be the approx box size for a single 10"?  The smaller box the better but I dont want to totally sacrifice the bass performance rather Id like to find a happy medium. A kicker solo baric 10" is recommended for a min of .66 and a max of 1.0 Sealed.  Would the eclipse require larger?

The aluminum driver will work in a .5 cu.ft. (net) sealed box, howver if you can give it more airspace it will do a much better job at producing low output frequencies and play all frequencies with authority, in other words, get as much airspace as possible up to a maximum of 1.25 cu.ft gross volume.

The q-form encloser for under the rear seat can be bought for the left or right side.  The picture you see in Crutch field is for both units connected with a amp rack in the middle.   As far as the jack and tools in the NBS trucks go.  You could put them about anywhere you can fit them.  Aren't they just in a bag under the seat back with a bolt holding them down?

oh and the BOSE system has only been available in trucks 2003-up.  Yes, some SUVs had it as early as 99, but trucks only after 2003

There isnt any kind of a converter or anything like it to allow you to run an external amp from any factory headunit using banna plugs. The only way would be to connect the headunit to the amp using the high input of the amp.

99 2 door thanks for the info on the bose. Ya the jack bolts down in back. Its a good place for it I just want to make sure I can get at it if I should ever need to hopefully I won't. It was the MTX thing that I saw. I have since seen the Q forms in their magazine which looks ok. Once I get the sub choice made Im leaning toward kicker because we have a local store that sells them and I know the owner hes always treated me pretty good. I dont know where to get eclipse other than online which could be a pain if there are any problems with it.

If I decided to use separates in the front door would I need to make a special bracket? Id go with a 6 1/2 and a tweeter. Also any problems getting the door panels off the front and back doors of this vehicle? Anything I need to know not to break anything?  Thanks for all the help here so far.

bpunzel I have seen aftermarket converters that convert the signal to low level just in case your amp doesnt accept high level inputs. 

All replies are welcome thanks alot.
