Apologies for confusion, was piling onto earlier thread where it appeared one user had a later model F150 like mine. Apparently they made a few key changes in the 2009-10 models around that damn subwoofer.

 

How did you get to the RCA input?

 

JimK did you ever find a sub that was plug and play swap for the factory sub in the 2009-2010?

 

The closest ones I've found are

1) Kicker 10CVT82 (2 ohm SINGLE voice coil)
- As noted earlier, SONY sub amp has 4 outputs (feeding two voice coils) so I'm not sure if driving only one voice coil is workable with this amp or not
- This one fits the opening perfectly (including the shallow 3.5" depth)
- Never owned a shallow-mount CVT so no comment on sound quality

2) Kicker 10CVR82 (dual 2 ohm voice coil)
- Probably the best overall solution I'm guessing
- Requires a 3/4" mounting spacer because it's 4.25" deep (top-mount depth)
- Guessing it sounds better than a shallow mount
- But that extra 3/4" puts the woofer cone very close to the floor, so may need to put some washers under the sub amp mounts to lift it up a tiny bit
- Also, for a sealed unit, that screw hole on the top side of the sub box would have to be sealed off (that's the screw that feeds into the back of the SONY subwoofer magnet - obviously it is now removed with a different subwoofer)
- I tried the 10CVR84, but at 4 ohms per voice coil that SONY amp didn't push it hardly at all

I took out the sub again and measured the resistance of the coils and the amp's outputs. The voice coils measure around 1.3 ohms each, just as noted on the sub magnet (1.2 ohms is stated). The voice coils are separate and isolated, wanted to make sure the sub wasn't wired differently than expected because 1.2 ohms is super low. The amp's outputs are all isolated as well, so basically no information there.

Some guys claim that the Sony Sub amp, or the DSP module that sends signals to the sub amp, are limiting the bass at higher volumes. One other guy on these threads says they measured the signals and no such limiting occurs. So I'm not sure what is correct, I don't have the instruments to do such a measurement myself. The amp is fed with a not-so-thick power supply wire so that leads me to believe it's current draw is pretty small - I guess I could measure that actually but am leaning towards installing a separate bass box. This thing is just a lot of hassle.

 

I used a Kicker 09S8C2 8" dual coil at 2 ohm. Made a 3/4" spacer ring out of mdf and used 2 part epoxy to fill in the hole where the old sub was back mounted. Then installed a ZX500.1 on the back wall of the cab to power the sub woofer. I also had to raise the sub woofer enclosure about 1.5" due to the use of the 3/4 mdf ring and also because the new sub moves alot further than the sony. To get the old sub enclosure to raise the 1.5" i had the remove the plastic handle on the bottom of the seat (not a big deal my baby seat is on this side). The seat release can still function after romoving the plastic handle by simply pulling the cable that attached to the handle. Just not the prettiest thing if that seat is left in the up position.

The nice thing about the zx500.1 is that it takes high level inputs as well as low level, and it has a 5 volt dc offset to turn the amp on. All I had to do was run power and ground to the new amp and use the wires going to the old sub and spliced those into an rca plug and used the high level inputs and the offset to turn the amp on and off. I did this at first because I wanted to hear how the sub sounded in the factory enclosure, with the intent of bypassing the factory amp and using the low level inputs for it and a relay tied to the switch to power the amp on and off after determining if I would have to build a larger box.

Later on I decided I was satisfied with the output and removed the factory amp, using the low level inputs. For some reason I could not get the same output from the system. I don't think the low level inputs to the stock amp has the voltage necessary to be used efficiently on an aftermarket amp, I could crank the gain all the way up and get no distortion or get even close to clipping. Eventually I wired it as I did previously. I am probably getting some distortion running through 2 amps but it is only for low end bass and truthfully it sounds good to me. I will have to agree with what was stated earlier that the sony amp is the culprit to killing the bass at high volume because after bypassing the amp I did not notice a decline in bass as the volume was increased.

Truthfully I think the stock enclosure is too small, but for my needs this set up pounds. People don't here me from a block away but that is not what I am after, and I have not lost valuable space in the back seat.

 

Thanks for the great info guys. I've got the audiohile system in mine and purchased a Sony sub from a buddy. Does anyone know where I can get a plug for the amp on the stock sub. Couldn't find under the carpet and need it to be able to use the setup. Any help is greatly appreciated.

 

I just joined this forum, I was looking for subwoofer discussions on google and ran across this topic. A week ago when I seen this topic due to me wanting to enhance the bass output in our 2010 Raptor. I told myself I have 3 different 8" subs I can try in there. But the ohms and DVC threw me off (I only had SVCs 2-4ohm and 1-8ohm) . So I did the smartest thing I could think of rapidly and cheap for a quick fix.

See how there is a 5x6 piece of blue fill in this pic?



I found an old pillow and took the stuffing out (white polyfil) and loosly filled the box up. Much better sound all from stock components. I encourage anyone with a '09+ sub try it out. Everyone has a old pillow I did leave the blue insulation in there btw. . The stock sub won't sound like its clipping out anymore.

 

I know this thread is pretty old but I have a 10cvt84 sub that I would like to install in a 04 factory box. How do I wire this sub up with four wires coming from the stock amp? Does anybody know if the stock amp can be bridged?

 

Let's bring this one back!!! Just looking over craigslist and eBay and wow there are several 8" subs with rms rating of 80watt - 125watt- 150watt -200watt rms all dvc too. I want to try and utilize the factory amplifier to see what I can get from it. Any new experiences over the years found out there? I'm doing a budget upgrade and already have the oem subwoofer setup so let's push it to the limits instead of throwing it out. I upgraded all my door speakers and will amplify them, and putting in an older eclipse 7 inch DVD screen that was almost free. I'll do the spacer ring thing if I must, just looking for the best replacement sub. I am a sound qualify r&b rap jazz guy.

What subwoofer rms ratings do I need to avoid? Factory from what I read is 100w dvc 4ohm???

 

kicker 07CVR84 has been discontinued. Any other plug and play options?

 

May have found one. Per Crutchfield:

Pioneer TS-SW2002D2

 

if i would replace the 8 in sub with the Kicker CompR CWR84 (43CWR84) could i use the factory amp or would i haft to replace it and if i do what should i replace it with

 

did that sub work?

 

I want to keep my stock 2014 f150 screen navigation radio but I want to add a system , so I can hook up the amp remote and rca to the stock radio ? Does anybody know
what I need

 

Does anyone have the pin out for this amp? It’s from the 2009 ford f150 platinum. Thank you
