Subject: how many watts can alpine type r handle
Date Posted: May 24, 2008 at 1:35 PM
I've heard the alpine type-r's can handle 750 rms, and even 1000 rms watts. I have a 4.5 cubic inch ported box tuned at 35hz for 2 12's, with my two jl 1000/1 amps, I wanted to see how it would sound. but then i also have a box for four 12's, , turned at 35hz i believe, my friend gave it to me but its hard to fit in my trunk because its two seperate boxes that are 2.5-3 cubic, but they are to be bolted together to make 1 box. any help? would the 2 alpines in the one box i described be louder if i push them at more watts? i will take a picture of the box soon.

A Type R 12 can handle 1000 watts safely IF you know what you are doing...most people don't and fry them with rated power.
I ran 1200 watts rms to mine daily and it did fine.

I ran 2500 RMS to one 12 in a ported box once, it lasted until I didn't want it to last anymore  ------------- 2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

what do you mean by "if you know what your doing"? because i want to try and run 2 alpines, 1 on each jl 1000/1's, i have 6 alpines total so I want to experiment with something.

I think he means, you can run a ka-gillion watts if you want, as long as you know when to stop turning up the volume. You can hear when a sub is starting to cry for mercy.

"If you know what you are doing" means keeping the signal clean and unclipped also.

If you keep the volume down then the amp wouldn't be pushing "a ka-gillion" watts, so this doesn't make sense. ------------- 2013 Kia Rio -90a alternator

It makes perfect sense. I could buy a nuclear power station and use it just to power my jig saw, and my jig saw only, just because I have pretty much infinate power at my disposal does not mean I have to use it all.

How do I keep the signal clean and unclipped?

What I am trying to say is, if the volume is turned down the amp would not be pushing the full 'ka-gillion' watts. The OP didn't ask what the largest amp he can put on his Type-R, and yes a 'ka-gillion watt' amp would work, but the Type-Argh can still only handle 1200watts RMS -just cause that's the highest answer we've seen so far (from aznboi). ------------- 2013 Kia Rio -90a alternator

by properly setting up the amplifier

What you also need to do is make a proper enclosure for the subs. If you have a ported enclosure you need to make sure that you are not going to be pushing the sub past it's mechancial limits (i.e. making sure the sub isn't overexcurding). In a ported enclosure that is going to be more important then pushing it past it's thermal limits.

I have two type R 10" subs. I'm considering a singe chamber ported box. I can go a maximum of 5.7 cubic feet. That's probably WAY too big. I was wondering what the best size box would be and what port length ( 4 or 6 round) or total area and size of a square port.
Could I make a big O'l box like that work? Or any other suggestions?
I'm opened to going sealed too. Just looking for the best SPL I can get (at the lowest reasonable FQ)
Thanks for any suggestions

type r's and sealed boxes suck.
I'd recommend 1.5 cu ft for each 10 and tune between 35-40Hz.
If you want more SPL than anything than tune to 40Hz.
3 cu ft box with two 4 inch round ports 11.25" long will get you there

thanks aznbo13644!!! Say, do you mean build a single chamber box 3 cubic feet total internal for both tens and then add 2 4" ports 11.25" long? If so, is this tuned to 40hz or 35? I do want SPL, but would rather do 35 instead of 40 for better quality and sacrafice a few dbs. By the way... do you think an enclosure like this one could keep up with and/or sound better and/or play louder than 2 Audiobahn Flame Q DVC subs in a 4 cube ported box? I've got a little neighbor contest we started last month and I'm trying to ensure I've got those dang audiobahn's taken care of  Thanks for the help, I really appreciate it! PS... plan to run a Brtus 1501 hifonics amp to the alpines...enough power for them?

that should be enough power for them...well the box should be 3 cubes NET VOLUME...so after port/sub/bracing displacements.
Using two 11.25" long 4" round ports will give you right around 40Hz tuning and be short enough to have the ports on the same baffle as the speakers without having to bend them.
Unless you want a slot ported design I can make one for you tuned to 35-36hz that will rape those Audiocrap Lame Q's
I usually tune to 38-40Hz and it sounds fine...the SQ isn't bad at all...yeah the low end may not be as loud as 35Hz and higher maybe but really you're buddy probably has a high tuned enclosure as well...most likely prefab.

[QUOTE=aznboi3644]Unless you want a slot ported design I can make one for you tuned to 35-36hz that will rape those Audiocrap Lame Q's QUOTE] YES ABSOLUTELY! I'd love a design like that. Here's what I have to work with: Box has to be 11.25" tall. Has to be 17" deep. I can go up to 49" in total width. So I can adjust the width to what-ever you think I need. I'm using 3/4" MDF. THANKS SO MUCH!!!! As for his box... well, be actually built it, and it's built surprising well and solid... it of course has no carpet or finsh on it  Thanks for the help on this, I greatly appreciate it!

How's this look???

I am VERY IMPRESSED! How wide is the port, and long is it? I'll likely build it just as you have pictured above... but would it matter if I moved the port on the opposite side next to the subs? The port would then wrap behind the subs. If it would be better to have the port where you have it drawn, I'll build it there. Finally, I see the short brace in between the two subs. Could I keep that out and double-face the box? Thanks!!!!!!!! Nice Design!

aznboi3644, what box building software do you use?

not to hijack anyones thread but aznboi3644 do you have any diagrams like that, but for just one Type-R?

I use pencil and paper...then WinISD to get the cu ft and tuning.
Port is 5 inches wide by 9.75 inches tall.
That modeling program is just Google Sketchup.
You could doublt baffle it but I would leave the small divider between the subs. I wouldn't move the subs closer the to port...the subs may load unevenly
I was also going to add a brace from the front to the back
I'll post up the full dimensions for all of the boards soon

actually, just need the total length of the port... or simply the total area or volume of the port, thanks
