amp/sub question

My question was never answered in the audio forum so hopefully it will be answered here since this is for a 1st gen CL.

Do these setups sound the same? Would they work well with my set-up? I really want to squeeze the most out of my $$$.

12" Alpine Type-R 4ohm w/ Alpine 700 watt amp (500 watts @ 4ohms)
or
12" Alpine Type-R 2ohm w/ Alpine 500 watt amp (doesn't matter @ 4ohms) [cheaper]

If you need more info this will be with:
Front: Alpine Type-R's 6.5 components
Rear: Alpine Type-R's 6x9 coaxials
Headunit: Alpine CDA-9884
Amp: Alpine MRP-mxxx
Sub: Alpine 12" Type-R xohm
Yeah, a complete Alpine system!

Also, The Alpine Type-R is a dual voice coil sub. (250 watts each) Dose that mean I need a 2-channel amp? (for the sub)

BTW, Found em' for $100 on amazon.
http://www.amazon.com/gp/product/B0...R123P7WJRYS9F9J -2ohm
http://www.amazon.com/Alpine-SWR-12...r/dp/B0009NXN7K -4ohm

You don't need a 2 channel amp, you can bridge the 2 voice coils into one channel to get the most power out of your amp. The important question is do either of those amps go to 1 ohm stable? If not, get the 4 ohm, if the amps go down to 1 ohm, then get the 2 ohms, and bridge the amp down to 1 ohm.

no, alpine Amps are NOT 1-ohm stable, not even their mono-blocks, or their new PDX series digital switching amps

id still also say with the Type-X up front, since im certain those will fit better than the Type-Rs with little or NO modification........... and what made you decide on the all ALpine set-up??

and as for the subs... you can run the voice coils in independent by running a channel each.... but there are other waysto run them, itll all be outlined in the subwoofer manual when you get it so if you dont get it now, you might then... you can run them in series or parallel so as to only use one channel per sub

headunit... I never really liked the 988x series... but it works I guess

Ok, I think I get it.

I chose all Alpine because the hu has the exact specs and design I want (usb back, controls closer to driver, etc.) and overall I thing Alpine gives you the best bang ans quality for the buck. They look sweet too!

So the Type-X is really that much different than the Type-R? The only reason why I wanted the Type-R up front was to match the whole ALpine Type-R system. I guess I could go either way as long as it's Alpine.

BTW, I just found a great deal on a Alpine 700w amp so I'll probably go for the 4ohm subs.

Thanks for your help and quick response guys!

its not the sound quality or anything like that im concerned about... but YES in that respect the Type-Xes are gonna be better, but the back end of the speaker on the Type-X is a smaller size.. atleast it should be since its using different magnets, between the width of the Type-R magnet and its depth I just dont think its gonna go in without some fabricating of some sort........ tell ya what you can do though, go to crutchfield look for a spacer to turn your 6x9 slots into 6.5 slots, those plates will also come with an additional hole to mount your tweeters into, that way you can have your Type-X al around, but the Type-Rs will do just fine...... in the back id still say stick to Infinity, probably use those spacers and get a set of 63.7is, since the 6x9s will BARELY clear the back.... the added mid-range driver will definately even out the sound stage since thats less work that the dome tweeter has to do on its own

and good call on the alpine headunit, I definately prefer the Alpine interface as opposed to the Pioneer one.. especially once you cross into the high end lines where I sit at, I HATE that stupid Pioneer commander wheel, I much prefer my regular set of buttons and a regular knob. and in my case my Glide-touch interface bar REALLY HELPS working in the menus and seting up its standard internal processors....... dollar to dollar, thre really isnt a PIoneer unit that can stand up to mine

so type-x up front it is. Don't want it to end up like blackack's. No offense bro, probably sounds sweet. But I am kinda iffy on putting 6.5s in the back and I can't find the infinity kappa 4ohm 6x9s you were talking about earlier G22. So if the Type-Rs fit in the back, I'll probably go wit those.

I am trying to guide u away from that, that's why we're encouraging you to get the type-x's, i just went overboard on my sound, 400 watts in the back, 300 watts in the front

you can run 2-ohmers just fine.... but if youre looking for 4 ohm kappas you might have to end up buying 2nd hand. or I can try finding um for you here, locally, the shop I usually go to has some old stock still lying around, still new in box

the Type-Rs probably will fit fine, go ahead, I mean I cant really say anything bad against um, theyre great speakers, I just think the Kappas would serve you better

as for the 6.5s in the back thing, since youve got the subwoofer covering it, you dont need the larger cone area of a 6x9. you want the clarity of a stiffer more rigid 6.5. for SQ, Round > Oval, always, not to mention tne 6.5 are always cheaper and shallower mount than their 6x9 siblings

ohh. When you guys said that the Type-Rs wont fit I thought that you guys just meant up front. I could be wrong but mounting depth doesn't really matter in the back because there is nothing behind (or under) the speakers to stop them. Just open trunk space. I guess I am wrong tho? I'll double check tomorrow.

Anywho, I was looking into those Kappas and am liking em'. Sill kinda iffy about the 2ohm thing but I guess It won't matter. Still kinda prefer the Type-Rs if they fit. Really want to get rid of that BLOSE gill. Screw the whole ALLpine system set-up. That was a stupid idea. I decided on the JL 12w3. Heard my friends 10w3 the other day and was freakin impressed. I've heard MTXs, Kickers, Pioneers, and Type-Ss and unless the Type-R sounds a crap load better then the Type-S, it might compete with the w3. The Type-R may be louder but not as clean. Already started on the ported sub enclosure. Was thinking of doing a DIY but Crutchfeild already has a good one. I'll redo the list...

Front: Alpine Type-X 6.5 components
Rear: Alpine Type-R 6x9 coaxials /or/ Infinity Kappa 6.5 coaxials
Headunit: Alpine CDA-9886
Amp: Alpine MRP-M650
Sub: JL Audio 12w3v3-4

well the W3 and the Type-R fall into roughly the same price bracket. both by very reputable companies. so really its either or... but I think the W3 is more expensive by a bit........ either way though, the performance of the system is determined more so by the BOX, than the sub... save yourself some cash, buy the Alpine and put it into a good box

Yeah type-r's probably won't fit into the rear either come to think of it. I had to make spacers for my rear speakers

I raised my 6x9's 3/4 of an inch, and the trunk springs still hit the magnets

Of course you can see why with the difference from stock, the spacers i made can be seen in the back

Hmm... I did some measuring and found out that you guys were right about the rear. The Type-R is about 5-7mm too big (75mm) and hits those trunk spring bars. The kappas look like a good idea. For the front I found out that the Type-R (59mm) is shorter then the Type-X (65mm). Is this right?

BTW, got the measurements from the Alpine site.

youre gonna want the Kappa 6.5s, the 6x9s are gonna be as deep as those Type-Rs
