Stock 8" sub vs Aftermarket Setup

[AH64Medic]

While you can wire that polk to the factory amp, I wouldn't recommend it. the factory amp isnt going to put enough power to it IMO. You could however try it out first, if satisfied keep it. if not add a amp later on.

I agree with you on the moving the sub box around all of the time. I am in the process of building a center console to house mine. I realized I wasnt going to get enough bass from the stock location.

Do you know if the factory amp can be replaced with another amp so I don't have to find another place to mount it? Also did you run LOC to the factory sub wiring? I think that's how I ran mine right in front of the subwoofer plug. If that's not right/ideal where would you run it to keep the factory head unit for the time being?

Yea the factory amp can be replaced. you just get a amp that can accept speaker level inputs, and wire it accordingly. I have a aftermarket double din. Also I didnt have a factory amp in mine. Yes a LOC would be correct for getting signal to the aftermarket amp. Do you know which amp you have currently on your 10s? are you wanting to reuse it or find a smaller amp that you can hide in the panel with the factory sub?

I have 2 amps to choose from. Both are RF and are about the same size. The newer one says RF 600w and the other is an older RF Punch amp. I added a picture of the bottom because I'm kind of confused about these 2 amps being about the same size and having such different power ratings. If I use one to power my sub could I use the other to power my door speakers? Hey and thanks for helping me out with this. As you can see not too many people have given me advice on it.

I would run the 201s to each front speaker @ 4 ohms stereo.
Then run the 150s bridged @ 4 ohms to this Polk sub. http://www.sonicelectronix.com/item_12333_Polk-Audio-db840.html this is the single 4 ohm version

Thanks for all the help Shawn. I pulled up some diagrams on how to do it and ordered some new wiring and connectors. I will post some updates when I get it all done. Thanks again.

Not a problem man. I hope all works out for you.

I don't think my 03' Denali has a factory sub. Could that be possible? The shape of the grill is molded in to the plastic but it is solid. It has the factory Bose system.

03+ have the sub inside the console.

How did you get to the factory sub? More specifically did you have to and how did you take this thing off

 

[YukonXL04]

The little black knob unscrews like any bolt. Pull the upper pillar covers. Then the top and bottom door sills for the cargo area. Then you should be able to wiggle the drivers side cargo panel loose. You won't be able to remove it unless you also remove the drivers side rear seat belts and C pillars.

I've been hesitant about messing with the bolts because I wasn't sure if they screwed in or not

If anyone reading this decides to just replace the factory sub, I definitely recommend the kicker 40cws82 so that you get great sound without an aftermarket amplifier

 

[YukonXL04]

so I guess it worked out for you?

Yup! Thanks for the help

You simply removed old sub and dropped the Kicker in? Stock amp? And it sounds good? Seems too good to be true.

Yup. No after market amp required

Did you need to modify the box? I picked up a Pioneer shallow mount based on many good reviews for our Tahoe's and ring around the woofer does not come remotely close to fitting in the factory grove. I might just drill new holes and use silicone to fill in the old screw hole grooves to get a better seal. What did you end up doing? Does the woofer hit the panel if you mounted it to the front of the box like that?

 

[Mudfrog]

I tried increasing the hole like most say to do, I've gone through on both sides and still need at least 3/8". Guess I'm going to have to cut the face off and replace with MDF board. I'm curious what everyone did to use this sub in the Tahoe / Suburbans.

 

[Blue2002Tahoe]

The kicker i got fits in terms of size, But I had to drill eight new holes. I didn't have to make the box bigger or anything though, just new screw holes

 

[YukonXL04]

Tahoe's and suburbans have different boxes... What may have worked on a Tahoe may not on a suburban. Which do you have?

Also you are sure you got the 8" version of the pioneer shallow mount?
