Subject: 12’’ Alpine Type R

Hi,

First of all let me say I am a bit new to car audio so bare with me. I Have read around on the forums and searched for what I was looking for. I got a little help but could not really I find what i was looking for or not in a language which I understand, hence im a bit new to car audio. In the past week I have been searching around for amps/subs/head units for the car audio system that I plan on building. I have came to the conclusion that I 2 12" Alpine Type R's, but i have a few questions about them.

In my car audio system I am looking for power and sound quality. I have about 2000-2500 to spend and looking for the best set up for my money. I am looking to hear some subs that hit hard but at the same time deliver good sound quality. Speakers are already installed so that is not needed. From my reseacrh I have came to the conclusion that Type R's will be the best for what I am looking for. Thus I want to build a system around 2 12" Type R's.

Here's a few questions I have for anyone who can help.


1. If given the same amount of rms 500w (4 ohms) SWR-1242D and 500w (2 ohms) SWR-1222D what will be the difference between these two. Which will preform better? Which will hit harder? Etc etc... Which would you recommend.

2. Which AMP would you recommend for 2 Type R's at 4 ohms and 2 ohms? Remember I want to maximize each sub to peak performance.

3. What time ob box would you recommend? Which box gives best quality? hits hardest? loudest?

4. Anything else i should look at before making my
purchase?


Thanks in advance,
Osh

If you are going for sound quality a sealed box  is your best bet.  Post up what kind of vehicle its going in and I'm sure someone will have some more specific ideas for ya.

Also look into sound deadning the car prior to the install.

As far as a noticeable difference (1st question) I don't think you'll notice a difference with both getting 500 rms.

2nd question I'm sure you'll want to stick with alpine and I don't knwo there line to well so someone else will have to help you on that one.

3rd sealed.

4th make sure your charging system is going to handle your stereo system, alternator battery etc.

The car is a 2006 Lincoln LS Sport V8 /w 12 Speakers No navigation.

Yes, I plan on installing dynamat before everything else.


4. I was told to buy a capacitor and that would do the trick? The person said 1.2 farad would work like a charm.

About capacitors....alot of people here are completely against them, some are totally for them. I'm not a fan. I feel a properly built system doesn't need one, normally. For a stereo your size, I don't imagine it being necessary. other opinions will be different. It's a money thing really.

The Alpine Type R is a nice line of subs. Personally, i've grown very attached to my Infinity Kappa 10" It's frightening how well it performs. Plays lower than any 10 I think i've ever heard, and it's box is too small, can't wait to put it in the proper box. But yeah, the Alpine's great choice.

I kinda stick more to installing it, than keeping up with numbers, so as far as an amp goes, i'll let someone else tell you those numbers. The Alpine Digital series amps are alot more glamour than necessary though, cause without the headunit, the talking function is useless.

2 ohms @ 1000rms

$549.99

Correct me if i am wrong but I thought i read some place that an amp rated 500 RMS @4 ohms wouldn't have as good/clear sound as an amp rated 500 RMS @ 2 ohms. I could be completely off my rocker but who knows. Also thought i read (probably smae place) that a ported box would be better for over all sound quality then a sealed. From my understanding a sealed hits harder but won't go as low or sound as good when it hits low. I've always run sealed since I usually listen to alot of fast beat music like metal or alt and techno. The few times i have run or heard vented they always sounded less thumpy but hit the lows so much better.

One thing i do know, depending on how much room you have as this may not make much differance, a sealed box doesn't need to be as big as a vented box would need to be. If space is a premium you might want to consider a sealed box.

Feel free to correct me if i am wrong on all counts.

Oh and if you can avoid it, don't buy fron Crutchfield. They are a good place to buy stuff but usually alot more expensive then you might find locally or god for bid Ebay. Carefull buying on Ebay though. Great stuff at great rices but sometimes you can get a raw deal. I'm so far 3 for 3 on good deals!!

I've had the MRD-M1005 with two 12 Alpine Type R's and it sounded pretty clean.

The new pdx line i havent tried yet.

The 1005 should be enough for two type r's.

Also i've heard the type r's in a sealed box and prefer ported. Hits cleaner and not as muddy. I don't know why.

First, the difference between the SWR-1242D and the SWR-122D is only the wiring options - two SWR-1242D's can be wired for a 1 ohm or 4 ohm load where as two SWR-1222D's can be wired for either a 2 or 8 ohm load. They'll sound they exact same.

Either of the amps you listed would work great for this setup. If you've got the money, the PDX-1.1000 is smaller, and will do 1,000 rms at 2 or 4 ohms. I've used the MRD-M1005 to drive a set of Type R's in my own car, and was very impressed by that setup. But really, either one will do the job very well - it's more of a question of, do you want to pay a couple hundred extra bucks for the newer, smaller, cooler looking amp?

As for the box - You'll want to put your Type R's in a vented enclosure for sure (assuming you've got the room) - it'll give you the deep, powerful sq you're looking for. REMEMBER: The box is more important than the sub itself. Your box could make or break your system. Also, if you don't have the tools or skills to build a very good box for these, you'll definitely want to have one of your local car audio shops build it for you. As for the actual box dimensions, you'll want to follow what they have listed in the manual for those subs... I think it's 1.3 ft^3 per sub tuned to ~32hz.

Since your subs are going into a trunk, I would suggest sound deadener. And lots of it. All over.
Also, make sure that your car's electrical system is going to be able to handle all that power. Also, make sure you've got the right size power/ground cables running to your amp.

Oh, and whoever said don't order from Crutchfield... Don't listen to them. I have ordered a couple sets of subs from them, and they have had amazing support for all of them. Something breaks, they pay shipping to send it back and you've got a new one within a couple days waiting on your front porch. Very quick.

On a side note, what's the rest of your system consist of?

Thank You. Yes, I'm all about supporting the local shops in your area, but in the event they don't have it, go crutchfield long before you even consider Ebay. That guy has been lucky as hell so far. I personally, have gotten screwed there. Ultimately, you have no idea if the amp works or not when you purchase it on ebay. I was sold a burned up amp. But definetely check your local supplier first, we need to stay in business. But if all else fails, hit up crutchfield.

Thanks for the help, as fort the rest of my system i plan on the following...

Keeping my speakers stock. The Lincoln LS model I've got comes with the premium sound. 12 speaker THX system I believe there Alpine or Bose, not sure. Anyways what do you guys think about this? New speakers or Stock-they sound great with out a subs, but what about with them?

As for head unit
JVC KD-AVX2 /w sirus adapter
(https://www.crutchfield.com/S-dd3MOzT2s5n/cgi-bin/ProdView.asp?g=168550&I=257KDAVX2)
I like it because it supports mp3 dvds, also has a small screen for dvds, but isn't as expensive as a full blown screen /w dvd player. Also the fold away screens don't look very attractive when there folded in. Any input?

I just don't know how I am going to configure it to twelve speakers. Any ideas? I think I might just take it into a shop and have them do it for me, but I am trying to save a little money on installation fee's. My buddy knows a bit about audio installation. He said he would help me fiberglass a box and install the system for free.

Does that LS not have a factory amp that you could possible hook up to that HU??

Cuz 12 speakers are kinda a lot for a stock dash HU.

Im almost positive it does haven't really taken it apart yet to see. With 12 speakers though i don't see how it doesn't.

Have you already bought that JVC HU?

If you're going to spend that kind of money on a deck, I would definitely suggest looking at some higher quality alternatives. Take a look at the Eclipse line - very high quality decks for a reasonable price. I personally would not buy a JVC deck.

As for your 12 speaker system... I'm not sure what to tell you. If it was me, I'd swap them out for a nice set of components up front and a pair of coax speakers in the back.
If you really want to keep the stock system, I'm sure there's more experienced members on here that can tell you how to do it. Or you could always ask the guys at your local audio shop.

Well if you want to keep that system, and no one replies here, try starting a new thread and include specific details in the subject line, and I'm sure someone will be able to help you out.
