subwoofer install LX-450

[woodsman 44]

Zero LX options for rear subwoofer unless you convert to 80 series free air space sub..... wasn't happy with the cheezy LX center console one..lol..... so I just built my own

I went with the JL audio 6 1/2" 6W3V3-4 woofer, mini sub
I wasn't looking for "neighbors knocking on your door" bass, just needed to add bass to the mix to round it out...and this Lil' squirt did exactly that.

Because of very tight location and limited space I used 1/2" MDF recommended by JL audio for 6 1/2" sub which gave me room to make a 14"x 10"x 4.5" depth sealed box with a 0.25 cf....it just sqeaked in there. Speaker depth is 4.25" so added a spacer.

Added a 150w 4ohm amp under seat and ran wires under carpet and console.

Didnt sand box but used some stain and urethane for moisture control....won't be seen behind panel.

Secured it on 3 corners.

Cut rear quarter panel...small hole first to see where Im at, then final cut...

Not finished yet, need to add some foam behind panel and secure with new clips, I have a few missing

Installed amp under pass seat with rear heater delete...1" wide 1/8" thick aluminum flat strap to secure amp...

Thanks for sharing. I need to put a sub in the back of mine and this is a great way to do it.

I installed an Alpine PWE-S8 powered sub in place of the rear heater.

Very happy with the sound and straight forward install. Used a pin from the heater connector for 12v "turn-on" power.

I Custom fit Kenwood KFC- X174 6-1/2" in rear doors, with speaker mounting depth of 2-1/4"...made a 1/2"spacer out of DMF so back of speaker is spaced out enough not to hit window arm for up and down of window...

No JL's that would work?

I wish, but JL's are to deep to make work, like some other brand speakers as well....these kenwoods were a happy medium and not a shallow mount.

That’s cool. I had no idea there was that much dead space behind that panel

Yes, room to put some sound deadening in there..... but when you roll the window down it gets in the way of mounting a speaker...depth..

I'm trying to do something similar but in a 91 FJ80. I'm having trouble identifying the correct wires from the head unit to the connector that plugs into the factory sub amp. Anyone know the pinout on the sub amp connector?

Nice- thanks! Especially for the link to the awesome website! I’ll get some use out of it for sure.

Update

The JL audio 6 1/2" sub is unbelievably awesome...its hard to believe it puts out that much bass for such a small size, rounds out my whole audio system... lots of bark and bite...keeps up with the big dogs without compromising space

How did it go with the preamp subwoofer under the seat? stiil pumps? do you recommend the Alpine? thanks in advance.

No problems at all, still works fine...just make sure and put heat barrier underneath amp because of exhaust under that area...gets warm
