Hello all,

I just recently got a 2002 Supercrew in December. Im wondering how you guys have set up subwoofers in your trucks. My amp is mounted under my passenger seat and it is wired for 1 sub. I know I want 1 10in preferably a kicker or a rockford fosgate.

Do you guys have yalls subs under the rear seat or behind it? Did you have to buy a custom box for it?

Any advice is appreciated!

 

I have two 8's under my rear driver side seat and my amp under rear passenger side seat. Its a box i got off a guy here. You can find the box for about 200 online. It sounds like a single 12 and has a stock look to it too.
This is the one i'm talking about http://www.crutchfield.com/S-oD8BVwi...up.html?tp=129

I'm running a single 12" alpine type r shallow under my rear seat, great output and takes up barely any space. The box is just one I built in my garage in about an hour, nothing fancy, but gets the job done.

If your looking at shallows, I'd definitely recommend the rockford p3s over the kicker ones.

But the sub is gonna depend on what amp your going to be using.

 

I have one Memphis PR 10" downfiring under my rear driver's side seat in a custom ported box and the 250 watt JL amp is under the passenger side rear seat.

It hits much harder than you would expect one 10" sub to hit. It has great range and is very punchy much like a sealed box. It hits harder at all frequency's (especially lows) than my buddy's Ram 2500 with two of the same 10's with a 500 watt amp in a sealed box under the rear seats. Both setups were both purchased and installed at the same audio shop.

It, along with my Memphis door speakers and tweeters, makes for a great sounding setup. I am more than pleased and get compliments all the time.

 

Mine is a Supercab, but may still give you some ideas...

Ive only got a supercab but I made a small custom box for the rear. I didn't have the cash for anything fancy and this box costed me literally nothing. Everything was off-cut from work. Its the width of the tailstock hump in the floor but the sub is raised 1 1/2 inches off the floor. Amp is under the driver rear seat.

Thank you guys for your input.

heres an update on whats going on with my truck

I got a RF P3, already boxed and the guy who put it in for me cut out some back paneling behind the rear seats and sat it in.

Problem now is that it has a "hollow" sound to it when the bass hits on certain songs. I figured its because behind the back paneling its all metal. I messed with the settings and basically turned the bass down and it sounds better.

Just wondering if any of you guys have had the same problem or have any suggestions. I already thought of dynomat but theres no rattling so I dont see a use for it.

Any help is appreciated.

 

The hollow sound is more likely the box isn't braced/built properly so air is escaping or most likely the box is too small for the sub.

Check to make sure the box is sealed properly inside, if not get some caulk and go over the edges, make sure to leave the sub out for about a day while it dries, the fumes can damage the subs soft parts.

And go to Walmart and buy a bag of polyfill or a cheap pillow that has polyfill listed on the tag for what inside it and stuff the box. The general rule is 1 pound of polyfill per cubic foot of airspace. Make sure to stable the polyfill to the box or glue it or something so it doesn't move around, you don't want it getting up into the sub.

But depending how small the box is they're is only so much you can do.

And if your worried about it resonating off the back of the cab, you can use some foam tape in between or carpet padding, etc. for cheap fixes. Of course sound deadener would be best, but I doubt that's the problem.

 

I used old house speakers under the seat (12's), -old technic's and a 4 channel eq. Surprised I've never blown them, -stiil sounds good, lots of bass. Enough for me anyway lol.

 

Hollow sound is common to small air space sealed boxes. That's why I went ported

 

2 12" subs down firing, removed 60% seat and added an additional 40% seat

[Front seats removed for picture]

 

A hollow sound can also come from inadequate air space, or improper tunning. What do you have your crossovers set on?

 

Yea, who wouldn't port ? Mine are DEFINITELY ported.
