Hey guys, so I'd like to get a little more bass out of my stereo, but without the "non factory" look. So what are my options for adding a sub to my stock GMT-400 ('96) radio? It only as a casette play, and no external cd player or security.

 

Also what would be a good size amp and sub to go with for a regular cab truck, with the goal being to be able to get a decent thump out of it but nothing too crazy.

 

Thanks in advance

Now, I have a quad cab 06 chevy and have me two tens in the back and they sound pretty good, but being that yours is a single cab one of two things, do you have the bench seat or do you have bucket seats, if bench you will have to not mind scootin the seat up a bit if bucket you can either custom mount sub or subs in the center console or buy two separate angled truck boxes and put one behind each seat, being that the boxes are small I would recommend shallow mount subs to put into the box. As for recommendations, I have a Dual truck/angled box for 2 tens, the subs are Absolute Shallow mounts, they beat hard, had kickers in them but they are just too big and sound like crap, and the amp im runnin is an MTX Jackhammer JH300, that amp is fan cooled and has a bunch of features w/ bass knob. Oh also you will spend alot more money staying stock rather than going aftermarket because of the Factory system expansion modules are expensive and take up room. But up to you Good Luck hoped this help.

Here's a simple setup. Buy a low level converter to rca plugs out, use rear speaker wires for input, buy 2 10" woofers with 100 x 2 amp. Make your own box out of 3/4" mfd particle board the length of cab. Make the box sealed with a divider between the two spaces. Measure back of seat angle where you drive at, usually 5" top, 9" at cab floor. Also measure for speaker depth at the angle. Check ebay for converter for stinger or pac.

Ok, so I'm gunna need a low level converter to rca, and then just tap into the rear speaker wires and that will go into the amp? I'm assuming you mean at least a 200 watt amp? Also, I was considering only running 1 sub, would there be a very noticeable difference?

Also, any reccomendations for a cheaper amp and subs, I'd really like to spend as little as possible, but not have a cobbled up set-up either.

 

Thanks again guys

I cut the rear speaker wires, add to input of converter, output will be rca plugs, add rca wire to amp input. I have heard a one woofer setup, like two better. Yes, 200 watt amp. Check Crutchfield for options of amps and speakers. Later on you can upgrade front door speakers and add another 100 x 2 amp with an external crossover.

I know you said you wanted the stock radio, but if you chnage your mind, I ve got a slightly used Pioneer Ill sell you for $65 shipped to your door. Its not the most expensive one ever made, but its a nice one. I had it in an S10 but decided to upgrade before installing it in my 1500.

Heres the thread of my system i just did http://www.gm-trucks.com/forums/index.php?showtopic=131635

 

 

But all you do, what i did anyways. Get yourself a line out converter. Bring your wires from behind your deck into it then run the rca plugs to the amp. Then on the amp you come out of your terminals back to the wires you cut at the factory deck. That way your signal/power comes from the deck to the converter, then to the amp, out the amp back to the wire then to your speakers. Dont need to pull any door panels off or anything. I have a 4 channel kicker 250 watt amp. Pretty easy to do, just little time consuming but a nice look in the end.

 

So once your speakers are wired up for your upgraded sound you can bridge off your amp to your sub.

amp was on sale for $130 at best buy and a line out converter was $50 and i got the adjustable. Just basic 10awg for your power and ground. I used 16awg for speaker wire which is kinda over kill and just any rca cable with a left and right plug

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
