My Adventures in Upgrading the Subwoofer and Center Speaker

[Starship Enterprise]

OK, this subject has been talked about ad nauseum. Do we need a new thread on it? Probably not. But if it helps someone upgrade the 2 speakers without having to look at 10 different threads, why not?

I put in the Pioneer 10” subwoofer.

Red Wolf adapters (These made the new Pioneer sub literally a plug and play!)

And replaced the center speaker with the Dayton Audio 3.5” speaker.

Pioneer 10” sub:
Drops right in as everybody said. I rotated it ever so slightly so I could drill new holes in the sub box to mount it. Drill extra small holes!!! The screws need to bite. Sounds better but not much boomier. What did happen is that it had better soundwaves which allowed all the other speakers to sound better. (I have the B&O 12 speaker system). I noticed significantly better sound out the side woofers! It just made the whole sound system sound better overall. This sub replaces the stock 4 ohm dual coil with the same specs. By using the stock holes on the Pioneer, I saved about an hour of drilling and bending the metal ring and was now able to put the Pioneer trim ring on. And you can’t really notice the Pioneer logo is slightly tilted.

I drilled 4 new holes and put the grill over.

Things I noticed while listening to different songs on XM Sirius:
- Folding down the back seat lets more sound up front
- In Surround mode, the sound is fuller and more spatial, but if you isolate the sub with the fader, some songs struggle with the sub…you can hear a distinct squealing and unpleasant audio artifacts….but it depends on the song.
- In Stereo the sound is much stronger at the cost of being less spacial, but the sub is stronger and shows no bad sound artifacts.

Dayton Audio 3.5” Center Speaker.
I got this speaker because the OEM center speaker is 8 ohm, 12.5 watts. This speaker is also 8 ohm, which I believe won’t upset the sound balance.

Center grill pops right off. Just held on with 4 clips. Just pop off with trim removal tool. Remove the 2 screws, Unclip the connector, and snip the wires and solder them to the new speaker. If you look close + and - are marked on both speaker terminals.

Now here’s the hard part. The new speaker holes don’t come anywhere close to lining up with the two stock screw holes in the dash. There’s also no room to drill new holes as the windshield is just 2 inches above the opening. I thought about it a while and determined, if 3M tape can hold on my front splitter, louvers, rear spoiler, and side louvers, they can hold a little speaker on the dash.

So I peeled the foam tape off the new speaker, and double taped inside the little recessed sections underneath inside the metal ring recess, so the final ring of 3M tape has a flat surface to stick to. Then I trimmed the little plastic alignment tab off the center dash, and laid down a ring of 3M tape to the dash to receive the speaker. I connected the wire clip, dropped in the speaker and secured the edge of the ring with more thin strips of 3M tape. I determined it is NOT going anywhere! The speaker grill clipped on top of it…. no problem.

Testing the sound, I feel a massive improvement!

For now still going with Surround and having at least one back seat folded down to let more sound up front.

Hope this helped anyone considering replacing the sub and center speaker!

Thx for the write up and pictures.
I might be replacing the stock 9 speaker system with just better quality speakers that I can simply replace. Definitely want to use stock amps so it makes it a bit hard to find 8-ohm and 4-ohm speakers that have a low rms rating as stock.

If you just replace the sub and center speaker, You might just notice enough of a difference to make your ears happy. Start with those 2 and see how it sounds. At this point I am extremely happy with my sound system now!

Thank you for the write up and excellent pics.. My Dayton arrived today and the Pioneer sub has been sitting in the box for a couple of months now so it's time to get this done. First thing I noticed with the Dayton was the weight of it. Very heavy considering the size.. Gonna tackle both later this week.

Thanks!

Yeah the Dayton has a beefy magnet. Both speakers are worth the trouble of putting in, but really, once I resolved to just drill new holes in the sub box to match the Pioneer, and just 3M tape the Dayton center speaker, I literally saved hours of time.

Be sure to get those adapter cables for the Pioneer. They are also a huge time saver.

Yea I have the adapter cables for the Pioneer.

I'm thinking of sacrificing one of the low impedance Infinity tweeters I have and cutting off the mounting tabs and affixing them to the Dayton unit.
I dunno, I have some 3M tape around so that sounds easier.

I'm glad it all worked out for you and do appreciate your pics and comments!

I think you’ll like the quality of the Dayton speaker as it is. It is a nice little speaker!
