I'm not sure what the peak output is from the factory amp, but I did measure the impedance of the factory fender sub in my car at 2 ohms on each coil.oh dang a 12", what's the factory fender amps subwoofer output wattage and ohms? did you find a sub that will work with it?
No one knows. It has proven to be able to drive this 12" though. Only downside is Fender limits output as volume increases (probably to stop puny fender sub from blowing) so as you crank it it won't keep going with the other speakers. So if you plan to compete with bass heads you'll lose.oh dang a 12", what's the factory fender amps subwoofer output wattage and ohms? did you find a sub that will work with it?
Yeah the OEM connector and wires are stupid expensive. I think I'm just going to cut the connector off and wire it right in. You can see the wire bundle there in the pic, plenty of slack. I can put the second terminal right there next to the first and I won't have to extend anything.I got the RF 12" sub and built my own box. 24"x 24"x 4" using 1/2" MDF creates internal volume fractionally over the .9 cf requirement, fits below the tray and the sub fits flush with no spacer or ring. $3.89 x 3 for the wood, a few bucks for carpet and spray glue + the sub = <$100. I ordered the oem connectors from ECS - the only part that was stupid $$. I think it was $30 for the connector and pre-pinned wires!
As many others have said it REALLY makes a difference. Surprisingly, while it runs out of steam at higher volume, the fill at low volume is remarkable and at reasonable listening levels it works well. Actually shocking considering it's just the stock amp.
Did sound deadening on the hatch and under the rear seats too...
Looks like a great option. Can you describe or speak to the complexity of install?I put this in my car within the first 3 days of owning the car, haha.
I love bass in all my cars and have always had the systems that were excessive f-body trans am had 4 10s with 2 1200 watt amps, a capacitor and a deep cycle battery in the trunk! even the ex wifes cars would get small 10" or a 8". My mk6 gli has the fender set up so i just delt with that but always wanted more boom. But with this rabbit version you can only get the trash stereo so this was a must for me, and I'm beyond surprised with the loud and clean (for a 12") this puts out! i added sound deadener in the whole cavity as wheel which help a lot as well.
also you can use this with or without the spare in place and it fits under the false floor so you loose no space. I was skeptical at first as well due to not having the box volume but its legit surreal how much bass this put out... its at the "punk kid" levels for sure and shake the mirrors with easy and that with the bass booster less than 1/2 ways up.
Listen to Oh Mama by Run The Jewels. I did a back to back with that track between the fender and the RF in the box from AK. So much difference, I stopped messing with the sub-bass-mid-treb settings and just listened.
Removed the head unite and tapped the signal of both rear door speakers to get the signal to the powered amp (that doubles as the remote turn on for the amp as well.Looks like a great option. Can you describe or speak to the complexity of install?
Apparently I'm not as patient as you chaps. I tapped into the stock Fender sub output lead from the stock amp. That signal goes into an LC7i, then to an external mono amp, and on to 2 10s. The funny thing is I really don't need 2 10s now, because I never removed the stock sub, so technically I have 3 subs running at all times, but the best part is being able to control the overall level from the head unit.
The stock output of the Fender low end is just not at all what you'd expect from a premium sound system that has a billion speakers. But it is what you'd expect after seeing the weird concoction that is the spare-tire sub, itself.
My setup essentially sacrifices the entire trunk for my daily driving, but still affords me the shitty stock sub in the event that I need to disconnect my external subs+box for trunk usage. In a weird way, I actually can't wait until I'm too old to enjoy chest-thumping bass.
