if you're going for sound quality, I would not get P3's. They're loud, especially in a hatch, but that's about it. Last years P3 shared the same magnet as the T1, but this year might be different. It might be difficult to get "audiophile" quality out of a $200 sub. But your amp might make the difference.

I would lean more towards JL Audio 12w3's

or Diamond Audio's D3

I used to sell Diamond with RF. Very killer combo.

Recently I blew the sub. So what any audiophile would do, I decided to upgrade my low's. Since I still have more power available to my disposal, I decided to upgrade the enclosure to one of Mike's Zenclosures.



This enlosure can house two twelves with 1.10 cu ft. per sub. The mounting dept sits just under 8 inches. I've been looking into different subs. This is when I came across the P3 model from Fosgate. Crutchfield carries them for $199.00 each. http://www.crutchfield.com/App/Produ...12&i=575P3D212
All the specs seem to go well with the enclosure demensions and I will have enough available power to efficiently drive these subs. Looks like a fairly good choice to me.

Does anyone have any experience with these subs. Any comments or suggestions are welcomed.



I have two of them in a homemade sealed box. I only have 400 watts from an old school Crossfire pushing them and it absolutely EARTHS. I'd be scared to run a Soundstream Reference 1000 on them cuz of the rear windshield vibration.

Incorrect, one of the better SQ drivers: http://www.madisound.com/catalog/pro...oducts_id=1735

Even the D612's from Diamond can be found for around $200. As for other 12's - Focal subs are just over $200, and Zapco subs are under $200.........I could go on and on.

I'm going to research some of the other subs you guys listed. A happy medium sub with good SQ and decent SPL levels, that I can run around 400 rms, will be sufficient. Anything requiring more than 400 rms would be out of my league honestly....

I just looked up the specs on this sub. Not a bad choice.

Can someone please educate me on the 1st 4 specs, "free air ressonance & the 3 Q's"?

The sub I'd recommend requires a smaller box than that.

You know, I was really impressed with some of the drivers 350zspl recommended, but they were out of my league. In order to accomodate some of those subs, I'd have to invest a nice chunk of change, have another custom enclosure made, plus a new amp. I'm not willing to spend that much.

you may want to check the dimensions on that enclosure. The P3 has some decent excursion not to mention mounting depth. You don't want that thin fiber dust cover slamming into your wiper motor area or God forbid, not even be able to fit the wocfer in the box.

The enclosure depth is approx 7 3/4, so I figure anything 7 1/2ish should be ok. I could always add a sub ring spacer if need be. I believe Mike sells 1/2 spacers....

I'm happy with my 10. The 12s are $175 each I believe.

edit-I looked at the specs and noticed 1.25 would be fine.

I think that is the exact depth of the P3. You are going to have a problem. The magnet shouldn't be touching the wall and if you add a spacer, you may hit the deck lid. That's why I had to custom build mine after I talked to the guy that makes those. It was only about 80 bucks for ther 3/4 MDF, Jigsaw, glue, silicon, screws, spray adhesive, and black vinyl. It fits perfect and the airspace is almost dead on for teh P3s.

The RF website is down right now, but last I checked, they're mounting depth was around 6 3/4.

You're right about how close the hatch is to the top of the enclosure. I haven't test fitted the enclosure yet, but I can see there's going to be limited space for sub excursion. I don't forsee any problems though, because I don't have a factory floor board to begin with. I can lower the factory floor between 1/4 to 1/2 inch if need be...

Holy Christ! I looked these subs up and happen to come across a youtube video of four 18's powered by 17k watts. Crazy!

I'm still researching the other subs you listed under the "happy medium" catagory.

So far I've looked at the Digital designs 9500g series:
http://www.ddaudio.com/dd/caraudio/w...p?series=9500g

RD alphas:
http://www.acoustic-visions.com/~aco...vers/RD_Alpha/

They are impressive subs, but I don't believe I have the kind of power necessary to drive them. I checked out the owners manual for my sub amp this weekend. It's been awhile since I looked at it. I have a RF P8002. 400 watts x 2 @ 2ohm. I know it wasn't the best amp for sub applications when I purchased it, but my knowledge of different amp classes was limited at the time.



the power off that Rf amp
is not enough for a DD 9500, or RD Alpha

less power can damage a sub faster than more power

an RD sonance would actually work well with your power

i like the sound of the p3s. Since you said you are going for show, get a brand that is main stream. Ive noticed at judges go more for brands.

Well I had a big turn of events this weekend. I test fit the new enclosure. It fits well in the hatch, but I had a problem. I placed my RF T1 in there, and found that the passenger side of the hatch hits the top of the sub's foam. The plastic backing on the hatch under the windshield wiper has a hump in it. This is the part that hits the sub. I can lower the floor board only 1/4 inch, which wouldn't make a difference because the sub's excursion will cause it to hit the hatch anyway.

Looks like I'm keeping the original enclosure I have. It's 1.25 cu ft. I'll utilize 800 x 1 @ 4ohms on my amp and will just look into a more powerful sub than the RF T1 I previously used. The mounting depth in the original enclosure is 6 1/2 inches, so I'll have to purchase a spacer to add at least another inch hopefully.

I looked at the FI website. The BTL's were a bit much, but the 3 subs below were quite appealing. I really like the BL series 12, but it doesn't have cu ft specs for sealed application. I'm assuming it can't be used in a sealed enclosure.

Any opinions?

Since they come in D2 coils, I could crank the RF amp I have up to it's max setting. Supposidley the RF amp box stated the amp was bench tested at a 951watts output level. I'm not really too sure how accurate that is though.
