Subwoofer Enclosure .

Has anyone ever tried to install a Free to Air subwoofer to replace the OEM sub, you could still use a 10" sub with a bit more flexibility as far as enclosure goes. Feedback would be great.

Yes i saw your post and i was also thinking of doing the same thing as you so nicely done , what i was thinking was to do exactly what you did in your post but leave the back of the enclosure open and use a free air speaker using the car itself as the speaker enclosure. By doing it this way there would be more option for the depth of the subwoofer that ca be used .It's just a thought what do you think?

I prefer sealed enclosures for the tighter, more accurate bass. I didn't have to use a shallow mount sub in my enclosure and had enough depth to fit a 6" deep sub and keep the enclosure sealed. The stock enclosure maximizes that space behind the stock grill. You won't be able to mount a free air sub any closer behind the grill because it will hit it on excursion and the stock enclosure backs right up against the sheet metal on the back side. You might gain an additional 2" of depth by going free-air, if that's the route you really want to go. I'm just not a fan of free air, or even ported enclosures in the auto environment. Like I said, I prefer the tighter bass. I cross my subs over low (50 Hz) and mainly just like a good solid bass drum kick when listening to my hair metal 😁

I think i am going to add a amp to power the 8" first and see how it sounds that way with a dedicated sub amp. can you tell me how much power wire did you use from the battery connection to the amp in the back. Thsnks

I used 4 ga. power cable and I THINK it was 15' (it was left over from another install), but it didn't quite get me all the way to the back corner. I was 2'-3' short, so I used a fused distribution block to get me the rest of the way since my plan is still to add a 2nd amp too. I would say go with an 18'-20' cable to make sure you have plenty of room to snake it around... you may have a little left over if you go with 20', but that's better than coming up short!

...if you're planning to try to power the stock 8" sub with an aftermarket amp, be careful. It's dual 2.5 ohms, not a very big magnet at all, and you'll blow the snot out of it with much more juice than the stock amp.

I always run my power cable down the same side of the car as the battery, so in our case, that's the driver's side. I always run the RCA's down the opposite side as the power cable, but on my V6 with no ANC, it hasn't been necessary yet since I just tapped the stock sub's speaker leads.
