Drop in subwoofer for alpine...

[JasonB]

Is there a subwoofer that can just replace the factory alpine sub without adding an amp or rewiring ?

Im replacing all the stock speakers with Kicker and my OCD is telling me to replace the sub

I'd like to know if this is possible as well; I really don't want to put a box under the back seat. I'm assuming there has to be something out there that would work.

Short answer is NO.
Long answer the Alpine sub is a triple voice coil, each coil is 2 ohms and each coil is powered on a separate channel from the factory amplifier. In theory you could use a low volume 10 inch dual coil 2 ohm sub and use 2 of the three factory channels but you also loose 1/3 of the power currently going to the factory sub. Unless some manufacture decides to build a direct replacement sub for the Alpine there really isn't any option. Also you cannot combine all three channels from the amplifier into a single channel to try and power a single coil or series or paralleled dual coil sub, there will be the likely potential for the channels to back feed into the other amp circuits and smoke your factory amp.

Do you know if the HK sub is also a triple voice coil? What about swapping with something like this with dual 2-ohm voice coils?

HK is a single coil. You could use that infinity 8" but would have to modify the 10 inch enclosure to be able to mount the 8 inch sub in the factory enclosure.

For the Alpine system you could use 2 of three channels to power a dual coil sub but would only get 2/3 of the power normally going to the factory sub.

At 2/3 the power what would be the likely hood that a aftermarket sub sounds better?

Kicker CompRT 43CWRT102

CompRT shallow-mount 10" subwoofer with dual 2-ohm voice coils

Was the sub i was looking at and just making a spacer for it

 

[Ryncody]

Yea, I wanted to do the same. Bought the punch shallow mount 2 ohm DVC . Only to learn it's triple voice coil open. I decided to wait. Does anyone know the alpine Amps wattage to the sub? Could we get 3 6" subs under seat n push it? Maybe like the dd 6" shallow subs

 

[Ryncody]

Also, I have the kicker key amps from my 2019 w the base radio . Is it possible to pull the feed from the stock subwoofer outputs and run into my high input on my amp, kicker claims it will work after stock amps up to 400 watts I have the key 200.4 which has a dsp. And the 500.1 which says it flattens the inputs .

I read somewhere that one of the channels is just the ANC signal. No idea how that works without interfering with the music coils though, so no idea if that's true. I would definitely like to know the power output if anyone knows.

The Memphis Audio M7 series subs are triple voice coil. I've been thinking of buying one and power it from the stock Alpine amp If they were not $400 for the 10" I would have bought it yesterday. Still holding out that Mopar/Kicker will have a replacement but it's now three years later for the 5th gen's and still nothing.

If a PAC CH01 is used on the ANC would this negate the third coil on the sub? Still learning all the issues with the ANC. It's not like my 4th gen and dropping in the Mopar/Kicker sub.

i took my out.you can buy the underseat kind.it has and amp built in them.and they can fit behind the seat.some work.but if you want to get the sound and space you want...

And then did you go with a separate amp and subwoofer?

yes..exactly!

Do you have to pull the dash and stereo to install these? Which packed sub did you guys go with?

yes you will have to pull out the dash to get behind it to plug in those "Jacks"not diffucult
