Hi, I recently bought 2 alpine type-r 12's(Alpine SWR-1222D). They are the 2 ohm ones. I don't have a car, but I'm going to put it in my girlfriend's car. I wanna learn how to make this all from scratch. My amp is a Alpine MRD-M1005. My head unit is an Alpine 9835R.
Here are the specs for the subwoofers:
-12" 500 watts RMS (1,500 watts Peak) Car subwoofer -Frequency Response: 24Hz - 500Hz -Kevlar Reinforced Pulp Cone -High Excursion ¾" Santoprene Surround -Dual Voice Coil -Custom Cast Aluminum Frame -Integrated Leg Vent System -Bumped Backplate -Heat Transfer Plate -High Strength Brass Voice Coil Bobbin -Double Stacked Magnets -Oversized Parabolic Dustcap -Magnetically Optimized Motor Structure -Designed and Engineered in the USA
My question is.. do you guys think this is an easy set-up? This is the first time I've ever wired a system together. Making a box seems really confusing to me, but if there's a simple guide to one, let me know.
Does anyone know how hard these will thump? Are the 4 ohm ones better if I'm using only one amp? I heard the M1005 is the perfect amp for 2 alpine type-r 12's.
My girlfriend's speakers are stock car speakers and I was wondering what the best speakers to get for the 2 front side speakers, tweeters and 2 6x9's for less than 250 all together.
You're going to get 700 rms to those 2 woofers. You'll need to wire them each to a 4 ohm load then bridged to the amp at a final 2 ohm load. Should do alright. If you do a ported enclosure they'll get plenty loud. Lots of people run the type Rs and seem to be happy with them, very popular sub.
Is there a diagram online for this? I also have a JL 1000/1 amp. Do you think it's better to use the Alpine or the JL 1000/1? What kind of wires should I buy for the Type-Rs? I still have 400 left to spend so I was fixing to spend 250 on speakers and 150 on wires and such. Is it a good idea to also buy a capacitor? And if so, which one? I really don't want my subs to blow cause of an idiot mistake I did.
That amp does 1000watts at 2ohms which is perfect for you. Use this calculator to figure out how to wire for a 2 ohm load. http://www.the12volt.com/caraudio/woofer_configurations.asp All you need to do is select 2 speakers and 2ohm dual voice coil.
v This is a good link for box building v http://www.reaudio.com/speaker_box/LPort_Box_Calc.html I would suggest 4-4.5cuft @ 35hz
Either the Alpine or JL amp will work fine, I doubt you will notice a difference. Just use the one you like better.
As for wire I would suggest http://www.knukonceptz.com/ You can get both the power wire (I would suggest 1/0 gauge) and the rca's. You would be fine using regular 14gauge speaker wire or anything up to 8 gauge to wire the subs to the amp. You dont need a capacitor.
Make sure you set the gain on the amp properly and you shouldnt blow them.
I am currently running 2 12" type-r's myself and I love them. The can get very loud in the proper install.
i dont think most girls wud want it overly too LOUD so id do a sealed box with each sub in about 1.25cuft which is easy to make & u can DIY
u might as well go alpine for the entire set - i was in car yesterday that im doing a box for 2 10" type R & this car has alpine type R comps & type R 6x9s in the back too & it sounds pretty good ...though personally i wud NOT put any rear speakers in & just do a good pair of componets in the front alone
this why : http://www.glasswolf.net/papers/rearfill.html .......
Wow really sweet guys. Thanks for your help. I appreciate it very much. When I get everything for my install and build the box, I'll let you guys know how it goes. You guys are awesome. THANK YOU VERY VERY MUCH.
Oh and my girlfriend doesn't really like it loud, but I do. I'm driving in her car a lot so I like to thump as hard as possible. I'm fixing to save up for 2 12w7's whenever I have extra money again.
Yeah I don't think I'm going to buy rear speakers. The set-up is going to be in a 1997 2 door Integra. This is going to be great.
^i agree. Also,i think you will be pleasantly suprised at how good those type rs will sound. My little brother acually has the same car with a set of type r 12s ran on a aq1200d. Its amazing how loud they get! You wont be disapointed
Is there a site on where to buy the perfect L ported box for 2 type r's? I think I quit on trying to make the box. It's pretty complicating for me on how to set-up and build the box. I kinda ruined the box I was trying to make.
