Thanks for confirming what I'm experiencing. Your installation thread was very helpful by the way.
According to JL Audio's specs the 10TW1-2 is a 2 ohms sub. Any idea on why the installer would have said it is 4 ohms?
I’ve taken a volt meter to countless subs and speakers of all kinds as I design and build home theater speakers and crossovers. I’ve never measured the impedance of a 2 ohm sub as 2 ohm. There is almost always some impedance in the volt meter itself and will measure at 3-“ish” or even 4 on a cheap meter. I have the 10TW3-D4 and each of those 2 voice coils measured at 6 ohms and when wired in parallel they measured 3-4 when rated at 2 ohms. So if he was just going off a measurement from a meter, the 2 ohm sub may very well have measured at 4.
Whichever one they have on Crutchfield. Thats where I ordered from.
There is no TW1-1. You have your choice of TW1-2 (2 ohm) or TW1-4 (4 ohm). You'd pick whichever one is best compatible with the amp you're running. This sub is easy to wire as it is a single voice coil.
Thank you for the clarification! I guess TW1-10 was a typo in the original OG post.
Should work well. The TW1 is a 300w sub and your amp pushes 300w into a 2ohm load. So you'll want to get the TW1-2. Both your amp and sub will max at 300w. If you buy the TW1-4, you'd only be able to use 150w when pushing the 4ohm load.
That’s what I thought! Thanks! Dang this sub is expensive.
That seems strange to me -- it fits the Gen5 (2019-2023) as well as the Gen6 (2024) so I would be surprised if Ford changed the shape of that under-seat area for the 2025.
