JBL Premium Upgrade. Replacing speakers and subwoofer.

I realize the start of this thread was a few years back, but here is hoping the original poster will see this post, or someone else can help. I want to install JBL 64SQ (6.5") speakers in the rear door. Crutchfield says the speaker will not fit, because the mounting height is too great. The height from the JBL 628s used in this build is 22 mm (and a rubber baffle was used). The height of the JBL 64SQ that I'm wanting to use is 20.5 mm. Will this fit, not fit, or fit and be smashed against the door?

 

Let me check this weekend. I put something similar in the rear doors with no real issues.

 

The inside of the door panel has an extension to seal (not really) with the speaker. You may have to remove some of this extension.

I added 1 1/4” spacer/adapter to fit 8” mid bass drivers in the rear doors and they fit without issue. Eventually replaced with Skar EVL65s.

 

Awesome!

 

Did you not like the kickers? I have CS coming today for front and rear doors.

 

Sorry haven't been on here for a bit. The CSs were definitely an upgrade form stock. The 620's were an upgrade from the CS lol. Now I'm running Alpine type Rs front and rear pushing them with 100w each. 600w mono Alpine to the sub. It's a completely different animal. The 620s were repurposed into the roof pods in my side by side haha.

Honestly I thought the CS 6x9s sounded great once broken in with the Kicker Key I was running. They Key 200/500 with a speaker upgrade and a small sub is definitely the best bang for the buck.

 

I agree completely! I would add that sound deadening in the doors will make the 6x9s impressive!

 

Are the factory (jbl premium) dash speakers 3.5" or 2.75 and you made the 3.5 fit?

Has anyone had any luck or a good sounding system after upgrading the sub and head unit only in their jbl Tacoma? My sub is blown and don’t really want to spend a whole lot of money. Only replacing the sub would be ideal like with a RF p3ds2 2 ohm the same as the stock sub. I have an upgraded joying headunit so quality shouldn’t be terrible hopefully. Need some advice on this. Thanks!

 

I replaced the JBL sub with a Polk dual voice coil sub in the same location and the difference is definitely noticeable.

 

How did you wire the new sub?

would it be safe to wife the voice coils to become 4 ohm? Specifically, connecting a jumper wire from voice coil #1 - to voice coil #2 +. And then connecting the sub wires to the other voice coils? Thus making a series connection. Asking this because the Rockford Fosgate sub is dual 2 ohm and the amp would support a 4ohm series connection better right?

 

Here is what Polk has.

 

Did you get a dual 4 ohm?? Thanks for the diagram

 

Yes and wired it to go 2 ohm

 

Is this the sub you chose? It’s the only polk sub I can find with 4 ohm and the correct mounting depth.

 

I got the MM842DVC similar.
You need to trim away some of the plastic at the back of the enclosure. Easy to do with a dremel

 

Ok I found that one.

What year is your taco? And did you care about the high rms rating compared to our amp that only produces less than 150 rms?

 

2018. Sounded better even with stock amp. Then got this for my birthday a few months after. which really woke everything up.
