Trying to figure out how to put my infinity sub into my 02' I want to put it under the rear seat, any suggestions on best sounds boxes. I have researched some pretty cool boxes, but curious to hear guys opinions? Also will I need an after market head unit or will the factory head unit run 1 12'' w/amp Thanks GMtrucks!

the head unit should run the amp and sub. although you might need a hi to low converter. doing it this way works great ive done it in the past, only draw back is the sub is not individually controllable through the head unit, but you can still manually control it at the amp.

This is my first post, figure I'll offer some advice before I start asking for it :)

 

As for your sub box, first find a few that will fit in the desired location. Make sure the box is deep enough to clear the magnet on the sub (shouldn't be a problem). There are three basic types of boxes but only two worth mentioning. First is the sealed box, historically it has produced the cleanest and deepest bass, but not the loudest. Second is the ported box. A few years ago I never would have recommended a ported box to anyone unless they just wanted loud, obnoxious bass within a narrow range of frequencies. However many ported boxes have evolved, and their ports have been tuned to compete with sealed boxes while still providing great output. Here is an example of the type of ported box that changed my opinion on them: Bassworx 12" Single Ported Enclosure

 

As for supplying a signal to your amp, some amps have high-level (speaker level) inputs. Others will require a converter as FTW666 said, that will bring your speaker level signal down to pre-amp levels. Either way, there is no need for an aftermarket headunit, unless you want more control. One idea is to disconnect your rear speakers and use wires to the rear speakers to supply your amp. This allows you to control the amount of bass with the fader control (rearward = more bass). The loss of your rear speakers will hardly be noticeable to you and may even improve overall sound quality as the highs and mids should sound like they are in front of you (think of a home stereo) while the bass is more or less omnidirectional.

 

When I ran a competition quality stereo I only had component speakers up front and a single 12" sub. Hope this helps, good luck!

      Is 2027 GMC Yukon Getting a 682-HP Supercharged V8?

      By CaptPat51 · Posted

      Would you supercharge the 6.2L on a 2021 GMC Yukon Denali XL with ProCharger?.... 605HP is the stated number without going crazy - it's not the LT4 682HP package, but I'm tempted to install it... This vehicle was ... not... recalled on the engine swap - but I don't really know if that means ...don't do it... or do it;)    Maybe i should start a prediction market pool on it in case it blows up;)   Any thoughts appreciated - I already OWN the supercharger - stopped the installation when the recall was announced and now it's taking up space in storage until I can solve an electrical issue with the vehicle...  4th GMC suburban-equivalent truck - I like them a lot - when they don't a) discharge their batteries randomly, or b) throw a rod at highway speeds;)

      We tested the sleep mode with an ammeter in series with the negative battery terminal - 30amp fused - so we do know the actual shutdown and non-shutdown current draws and timing of the shutdown sequence.  We just have no protocol information to determine what module is issuing the network keep alive.

      Brake Pad Warning Message

      By Vu1can · Posted

      TrueBlue...Even if you don't have that info stuff displayed, If Mr. Computer thinks there's something you should know about, it will pop up a warning message no matter what else is being displayed. I keep the speedometer displayed all the time, yet the brake pad message pops up anyway.

      BTW, the 11.5amp draw is all the usual systems active - it's not a single draw - that's the "we're all awake" state of the vehicle - forinstance if the power steps are actuated, the draw will spike to 22amps for that operation.  when the battery is disconnected and then reconnected, the vehicle shuts down that one time only - and we see a 10-15minute progression down 11.5  10.5  9. 8 6. 5. 1.6... 500ma... and then off to sleep at 40 milliamp... as expected.  So we know it's a module that is simply refusing to allow the SDGM to proceed to the sleep state.  We do NOT think it is the telematics VIM module - since we already duplicated the problem with the "VIM bypass" solution installed (we reverted that since it also disables the gmc app - but it does not appear that the telematics system is the culprit).  We've replaced the rear heater control module, tested without the wireless charger, and the other modules on CAN Bus 5 - but still something is keeping us awake and removing X2 from SDGM allows sleep to proceed.  We cannot diagnose from OBD since OBD drops off at about the 9volt level in sleep mode and we can't communicate with the vehicle - also we can't trace the SDGM internal packets from the OBD side - we have Autel Ultra.   Any ideas on why disconnecting X2 would allow sleep to proceed appreciated.  This is no longer a repair situation - this vehicie is simply unusable in this condition and NOBODY at GMC Dealer can even understand what it is doing.  This is crazy.  We made these systems too complex and now we're paying the price.
