I was going to only run 1 M1d, but decided that I could strap a pair of them and they would run a ton more efficiently at 2 ohms per amp instead of 1. At the time I was just looking to run any korean amp (sundown, DC Audio, etc) and decided upon DD because they seemed to be of decent quality and cheap on ebay used. My alternative was to run a T2500... I could have gotten one brand new for 899-999ish, but my friends have personally seen a few with major issues -- they changed my opinion to run the korean amps for now. It might have cost less to just use JL XD 1000/1s (ebay or on sale). I didn't really think of that until tonight.



I ran the older Focal KRX2 tweeters and they perfectly fit in the tweeter pods. We used a soft spacer behind them inside the housing to keep them tight. (you would need something like foam). Extremely perfect fit!

The headliner was not difficult after you remove everything else.... I guess it just takes time. I think you are fine as long as you budget a few days. My roof still flexes, so I would recommend spending some time here and I think you will see real gains.

I am running full active. Both of these amps have a ton of power. Way too much in fact. ( with a 3.4db gain overlap the mids were loud on volume 6!). We had to turn down the gains heavily because the speakers were getting over powered, but we have tons of clean headroom! We ran new wires to the doors and used the stock wires into the doors to run the 8ohm tweeters. We drilled new holes (door-side) and used the existing holes (removing the rubber caps in the car-side under the molex) to run wiring for the mids. The molex was just so small we didn't think our over-sized 14ga was going to fit.

We used the ******** 6.5 door kit because it was less hassle/cheaper than doing it ourself. We had to trim the bottom a little for door panel clearance, but otherwise they were fine once we painted them.




I posted clear pictures of our door wiring. We heatshrinked the wiring loom in place at the ends ( ends are hidden in the car/door) so that it looks really clean and ran it through a grommet at the door.



I bought two B-stock packs from Second Skin and had some left over. I think doing the sound deadening is extremely important to get the most out of your install.

What sub were you planning to use? Hopefully all the information here helps you decide on a box and a whole setup. There is enough room in my box dimensions to build a decent 4th order.... that is something to consider. We are going to build one for a 12w6v3 using a similar sized box to mine.

A DC Audio XL 12 would probably fit in this box really nicely. It would be about the same weight as my BTL and fit really well in a 1.80 net cubic feet box.
Two mid-size 10s might fit well here (FI Q 10)
The new Rockford T2 13 might also fit well here.

- I'm not a fan of the W7s due to the weight, at this level I'm generally recommending Morel Ultimo Titanium (custom order non-US product) or Polk for SQ, though for ported applications it's usually Sundown or the RF-P2s for SPL.

- The great thing about amps these days is that available technology allows almost anyone to build a quality amp. While I would have gone a different direction for efficiency, there is quality throughout your build and you've chosen well.

- Highly recommend the Focal KRX series, though I do dislike their power rating, it sucks balls.

I agree with you 200% that sound deadening is crucial, especially in our car.
I already have all material and equipment for the install, although some design decisions remain open.

Deadening: Sound Deadener Showdown (https://www.sounddeadenershowdown.com/)
HU: Pioneer AVH-4100NEX with Scosche adapter but considering using this instead (http://shopddmods-com.3dcartstores.c...aro_p_433.html)
SIGNAL: MiniDSP (https://www.minidsp.com/products/min...ox/minidsp-2x4)
AMPS: ARC Audio 2300SE (http://www.arcaudio.com/p/se-2300), ARC Audio 4200SE (http://www.arcaudio.com/p/se-4200?pp=24)
(I have two JL Audio amps as well that I may use, an XD600/1 and XD400/4)
MIDS: Dayton Audio RS-180 (https://www.parts-express.com/dayton...4-ohm--295-374) I have the door adapters from ST as well.
TWEETERS: SEAS Prestige 1" (https://www.madisoundspeakerstore.co...-dome-tweeter/)
SUBS: 2 x Dayton Audio RSS-265HF (https://www.parts-express.com/dayton...4-ohm--295-460) in 4th order bandpass boxes vented into cabin through rear deck 6X9 holes (this is subject to change, I may still go sealed or vented...)

Some issues I'm facing are where to put the amps (they're huge) and subwoofer box config. Here is the 4th order design
Attachment 826166

Highly recommend against Scosche/Metra, the PAC dash kit is much better. I know both Phastek (Sponsor) and DDMods personally, though DDMods has an free PAC kit with the Kenwood Excelon line. There are much higher reviews for the Excelon series over Pioneer and double the warranty. For installation, you can check our feedback thread in our audio forum here.

Unless you're receiving the ARC amps at a significant price discount, you would be wise to consider the Mosconi line at this price level. The ARC appears to be putting out impressive wattage, though I'd be cautious with the low S/N and efficiency. I prefer products with decades of proven experience in this stage like the RF-punch line and Zapco (if purchasing new).

You've got some nice HU, Amp quality and cabin preparation there so I'm surprised with mids, tweets and sub choices. If you've heard this combo before and enjoy it then by all means .
