Adding Aftermarket Sub/Amp

[cmpcpro]

Funny, I was just thinking about this last night. My thought is to fiber glass half of the storage box and putting a shallow mount in it; having a combo unit. Not sure how it would work out though. I am debating really hard on trying it out for the hell of it..

I would be worried that everything in the other side of the bin would rattle to hell with the sub in there.. Wish there was another way to do it..

Yep, that is my dilemma. Seems like if you ported the enclosure toward the front and carpeted the rest of the storage box it may help but not sure.

Can someone measure the clearence under the rear seat on a double cab?

Hey guys I have been himming and hawing about putting another sub in my truck.. Even though I listen to Stern 99.9% of the time there are those times I like to rock out, like lastnight, and it sounds good, but I know a sub will make it much nicer.. The problem is I have the GM underseat storage, which is full I might add.. I really don't like the idea of sub boxes sitting on the floor infront of the rear seat, but I cant think of many alternatives.. Any ideas?

 

Thanks

Check out the Kicker Hideaway system. I had it in my previous car and it added that little bit of bass a stock system lacks. http://www.crutchfield.com/S-vTmi3TwCLdr/p_20611HS8/Kicker-11HS8.html

^ something like that interests me although it has mixed reviews on the quality and life longevity.

I had mine for two years, and never had any issues with it. I plan on installing it in my truck soon.

Thinking about ordering it.

I installed my amp and subs but when I turn the volume over 3/4 the amp goes into protect. I disconnected the speaker wires for the subs and it would still go into protect when I turned the volume above 3/4. I called MTX and they had me send the amp in for warranty but they called today and said it tested fine. Is there something I might be missing that has to do with the new truck?

not much, but if you are looking for a sub box...try here.

I was told by the guys at SuperCrewSound that this box also fits the 2014 double cabs.

hmmm has anyone confirmed if there is one in the Double Cabs? It's kinda confusing on GMC's site if it's only in the Crew Cabs

 

***EDIT***

My DC does have a sub. I put on some rap today and definitely felt alittle vibration from the front part of the console. It is really weak though

 

yea my double cab has a sub. You really gotta get way up in the front of the console to feel it. But it's there.

I'm sure it would sit in there but I don't see how it would be sturdy with the '14 floor being a lot more flat under the seat compared to the 07-13

Power from battery terminal. Ground to back seat bolts. Remote from Bose amp on back wall.

 

Several ways to feed the rcas. One you can use the output for the Bose sub on a powered RCA converter. You can also use a direct off the rear speaker wires. One thing is that most are mono amps for the subs. The Bose noise cancelation can affect the sound if you try and use both rear speaker wires for RCA taps. It reverses the phases on one speaker and causing the amp to be out of phase and kills the sound output. Use just one side and double tap into for rcas. This will repair that issue. Or you can always unhook the nisei cancel speakers. I wouldn't do that though.

 

Which wire is the actual remote wire on the amp?? I'm assuming its blue?

If you use the tray's interior, you're going to loose a bit of valuable space because of its thickness & the way it rests on the carpet. If you have fiberglass skills, you'd be better off making a mold of tray's exterior edges and then creating your box from scratch, using the mold to shape the ends that are visible. Then just saw your cargo tray in half so it matches up with new box.

 

As for stuff rattling in tray, just coat interior with dynamat or some tough padded rubber/foam (like the stuff used in metal tool boxes)

I'm trying to find a route for the power wire for my amp, from the battery to the back seat of my 2014 crew cab. I normally pop a hole in a grommet in the firewall somewhere, but I'm not seeing anything that will let me get through the firewall on this truck. Anyone done it? Help.
