@Rilot what is the model number of the kicker sub? Did you put a grill over it and how does it sound?
Thanks

Installed DD RL-SW10-D4 a couple weeks ago as well. Absolutely love the outcome. I got the Amazon 10” bar, but I think I would prefer the DD Audio one Joe above me bought directly. Looks to be a bit more coverage. Lucky for me mine is a weekend warrior and hardly anything ever goes in the trunk, but would be something to think about if you used the trunk often.
Did this sub have 8 screws instead of 6 for mounting? Did you just drill 8 new holes in the sub enclosure? Are you not able to reinstall the OEM trim ring and speaker grille? Did you use a wire harness or just strip back the factory wires?

Yes 8 screws I do believe if I’m remembering correctly. None of the previous holes line up so no big deal. I did use gasket tape on the backside to get a good seal when snugging up.

No, stock trim ring will not work without heavy modification as done by someone earlier in this post. The aftermarket grill works perfectly fine. Even did a Costco run this morning with a full trunk, no worries on any unwanted touching.

I used this harness, worked perfectly for quick connections without having to strip anything. https://a.co/d/hBSLxlh

Well I started the process and was able to save 1 of the trim ring clips. 😂

I am reviewing the subwoofer replacement options and the only place I can find the DD Audio SW10-D4 is on Amazon by WoofersEtc. DD Audio has it listed as discontinued. Is there a newer model? I checked reviews for WoofersEtc to see if the company is legit and it appears they are. Anyone have experience purchasing from them?

If I am not able to go with DD Audio, is there any on the list below people have went with and are happy? I am also on the fence of just going with the Pioneer A-Series TS-A250D4.

Polk DB1042DVC 85db
Polk MM1042DVC 86db
Alpine S2-W10D4 84.5db

Appreciate the help.

The Polks were my second choice after the RL-SW10. To bad RL-SW10 are discontinued great sounding woofer. Back during my research, I was leaning towards the DB1042DVC since it was cheaper than the MM1024DVC. I have used Polk 6x9s in the past and loved them so I had no concerns with them sounding good. At the time the RL-SW10 just edged out the Polk so I went that way. Whatever you choose it will be a vast improvement.

I contacted DD audio and they indicated that the 300 series has replaced the discontinued version. I still need to verify that it is a direct replacement and will fit. Although I’m not really sure what I’m looking for. I would assume dimensions.

it looks like you attached your bar grille with screws. I would assume these screws punctured through the plastic woofer box. Did you put any silicone in the holes prior to tightening it down?

The 300 series will not fit. While the mounting diameter is fine, the mounting depth at 6" is a no go. The RL-SW10 was 4.75" and I think there is like 5.25" available. Not 100% on that, but search this site and someone had measured it out.
Yes the grill mounting screws just screw in after I drilled a pilot hole. Be careful it is thin wall plastic. I used #8 self tapping screws but should have used #6 in retrospect. If you don't plan on taking it apart then adding a dab of silicone won't hurt.

I found it on Amazon from the same seller. Shipping is a week out. Looking forward to hearing the difference, but not sure how it will sound with my top down .
Mine is a coupe. But the bass is better with my windows open. I'm sure you'll be satisfied with it. Now it does take time for it to break-in. Mine took a week or so and it keeps sounding better.

Tonight I went ahead and installed a Orion XTR XTR104D into the factory location, I little Dremel work to the box and it was installed in 20 minutes start to finish . Since I had a pair of these laying around thought lets give it a try knowing dang well the enclosure is far to small since these require about 1.35cu ft of internal space and the amp is super weak and god knows what the factory DSP/EQ settings look like. Well its far more musical and accurate but its missing and I mean missing anything below sayyy 30hz and lacking sub 45hz even with 8oz of polyfill but above that its a plus lol. I ordered the SKAR box that takes the place of the factory box to give that a try. Its 1.0cu ft so 2-3oz of poly fill should help. If I can talk myslef into doing the rest of the system I have a ton of high end old school stuff here. I'm thinking I will allow 40lbs of added equipment if I go that route not a gram more lol. For amps I have a SS 644,700s,10.0, Reference Picasso. Subs 2 12" Orion NT gen 1 ( carbon ones) and a pair of SS Velvet hammers(one fo the best 10" drivers for sq/sql in my book plus they are mega sensitive like 94db), Mids and highs SS SPL 5.25'' components, Diamond audio 6.5" 3 way components, 6.5" 2 way component set, and a Infinity kappa 5.25" 2 way component. Might go with the 644 powering all the Diamond Audio mids and highs and the SS 700s powering a single SS Reference "Velvet Hammer" which I loved the way it sounded in 1.1cu ft previously .. Long story short stock system leaves a lot to be desired esp in the low end range. If the larger box provides me the missing low end then I'm might to add the diamond stuff to the car and cross my fingers with the stock processor and amps. Has anyone added mids and highs to the 12 speaker BO system with good results or should I say acceptable results?

Read my post #703 on page 47 where I swapped out the door 3.5" and A pillar tweeters. After listening for a while I'm moving the tweeter crossover up more. The AMT is a little shrill crossed over where I have it now. Most recordings sound excellent, but some of the newer recordings I need to turn down the highs. Oh by way, disconnect the center dash speaker if you haven't already. Huge improvement with that alone. Also the DD audio RL-SW10A in the factory box hits hard and goes deep with the stock amp. It's not competition level mind you, but plenty loud enough for cruising around.

Update 9/9/25:
I updated the crossover frequency on the AMT tweeters to 8000hz. This did get rid of the shrill I was hearing. The changes that I made to date I'm very happy with. The Subwoofer is broken in with deep base, Midrange is crystal clear, and the Tweeter produces highs that the B&O lacked. The EQ in Sync 3 has both high and mid set to 50%. The low is set to 60%.

AHHH after reading all this I now understand how the speakers are all wired up..smh, If I end up going the route with new amps/dsp etc.., I may just swap the speakers and see how tolerable the stock amp(s) are at a lower independence(ohm) lol, maybe we get lucky and these amps can handle running 2ohm while preserving sound quality ,either way I'll keep everyone posted on this matter .
