I plan on getting an alpine type s 10" sub woofer but i am not sure what amplifier i would need. And it would only be powering the single type s 10" sub. Also to start my project i need a wiring kit preferably kicker (because i know they are quality kits), to withstand the wattage of this system... And i need to know what you think opinion wise, i want to keep everything alpine since i have the alpine head unit that i got when i purchased it. so yeah let me know what you guys think. and i haven't found a small box for that sub woofer either.. so i wouldn't mind you helping me pick one of those.. Thanks!:bow:

Alpine Type-S 10" SWS-1043D (300w RMS power handling)
Alpine MRP-M500 Mono Amp (500w x 1 RMS @ 2ohms)

I'm not a huge fan of either of them, but that is your matchup since you seem to be set on the 10" Type S and keeping everything Alpine.

Do you plan on installing this yourself?...or letting a professional handle it? Just use whatever wires they give you as long as they give you at least 4 guage for your power and ground. You won't be running a very high-end system, so you don't need to be too picky with wiring.

Also if you stick with Alpine's recommended enclosure volume for that sub (which you should), you won't be able to get a box that small. You will need to do something custom, which will require some research and skill on your part, or a decent amount of money to pay someone else.

Okay and i would be installing it myself. And what are the differences between the 2 type S 10" subs on the alpine site? one is 2Q+2Q and the other is 4Q+4Q?o.O

That is the impedance that the voice coils present to the sub. Without making things overly complicated, just think of it as lower impedance allows the amp to create more power. Notice the amp creates 300w x 1 RMS at 4 ohms, but it makes 500w x 1 RMS at 2 ohms.

With dual voice coil subs, you generally have two options:
- Wire the coils in parallel, which halves the impedance
- Wire the coils in series, which doubles the impedance

The sub I recommended has two 4 ohm voice coils. When you wire the voice coils in parallel, the impedance is halved and presents a 2 ohm load to the amp. The allows the amp to create it's higher 500w output.

If you were to get the sub that has two 2 ohm voice coils, one of two things would happen:
- You would wire them in parallel and end up with a 1 ohm load at the amp. Since this amp is not stable at 1 ohm, that could be disastrous. The lowest impedance this amp can handle is 2 ohms.
- You would wire them in series and end up with a 4 ohm load at the amp. The amp works fine at 4 ohms, but you would only be seeing 300w RMS when you have the potential to get 500w.

so with that being said i should purchase the 4Q+4Q sub.. and that amp that you recommended..

Yup, the SWS-1043D as mentioned above :)

Okay great man! so if i wired the sub to the amp in a "series" configuration, would a 4 gauge power wire be good, and 500 watt withstanding wire? basically one of the d series wiring kits by kicker..

Well remember, you want to do parallel. And that kit will do perfectly fine.

Can I recommend that you step up to the Type R (SWR-1043D)? It has better power handling (600w RMS), making it a better match for the amp. It's also not much more expensive.

I have owned three of Alpine's Type R woofers in my day back when I was in high school (damn, getting old lol). I ran two of the older ones back when they could only handle 300w each. Then upgraded to just one of the next generation ones when they increased the power handling to 500w. Now they handle 600w! They are solid woofers.

Check it out :)

I have purchased all of my audio from eBay...even my current setup. You'd be a fool to pay full MSRP!

Lets start off with the basic question. What do you expect from this system. Do you just want a little bit more low end fill, or do you want to shake?

BLSteve is spot on with recommendations. Except for the eBay, but that's just a personal hatred of mine. I firmly believe that eBay is full of scammers and cheep knock offs. CraigsList too. Again, just personal opinion.

As for a box you have to decide if you want it sealed or ported. Sealed will give a "flatter" response to your frequency range. Ported will sound louder at lower end output, but sacrifice upper frequency.

You don't think the type R would need a bigger amp or 500 watts is good enough, because the type R can do up to 1200 watts rms I think..

biglilsteve
09-27-2011, 02:52 PM
Nah, Type R is 600w RMS and 1800w max (max is a waste of a spec...don't pay it any mind). The amp will push it fine.

You should answer Rotz's questions too. Curious what your intentions are. Also, what's your budget (if any?)

09-27-2011, 03:25 PM
Rotz- I am interested in low end fill and to beef up my bass, so that it almost makes your ears ring but not soo much to where it rattly my door panels off.. haha and i want a sealed box. SORRY ABOUT THE DELAY OF RESPONSE, IM AT SCHOOL.
BiglilSteve- my budget is probaly 300$ thats a wiring kit, amp, and sub/box. but im willing to pay more if need be. right now i just need to buy my wiring kit and amp. so my dad can help me install it before he leaves tuesday morning.

i have a single 10 inch 2 ohm alpine type r with a clarion DPX1001.2 (1000 watt) amp. rockford fosgate 4 gauge wiring. for a month or 2 i have a custom fiberglass box (its .88 cf) and it sounds awesome! i had it pushed by the same amp (new)you are wanting and i didn't have it hooked up 10 minutes before i decided it needed more so i put my (older) clarion and let it pound. you will not be disapointed in these subs at all. i dont even have a new one either its the swr-1022d. you can buy one for $100 max and never regret it. i bought 2 and only ended up needing 1. do it!!!

2011TCfrenzy
09-27-2011, 03:39 PM
Cody2005- So you think the amp i want isnt good enough, thats why you put the clarion?

Guys my only worry with the Type R is it is going to take a bigger box than the type S and that means it will take up more trunck space.. :/

SWR-1043D: http://www.sonicelectronix.com/item_24186_Alpine-SWR-1043D.html
Amp: http://www.sonicelectronix.com/item_22381_Pioneer-GM-D7500M.html
Box: http://www.crutchfield.com/p_777BB1012V/Sound-Ordnance-Bass-Bunker.html?tp=127&nvpair=FFSpeaker_Size|10%22&nvpair=FFBox_Style|Ported

That's @ $400 without shipping. The price can go up or down, depending mostly on the amp I think. It's a decision between what name brand you want, and how much power do you want. The Pioneer is 400w RMS which I think will be plenty for a single 10 ported.

Cody2005
09-27-2011, 03:45 PM
not that it wasn't good enough. i could just tell i could get way more out of the sub. it didn't sound bad by any means. i just knew the sub would shine better with a bigger amp. its not a bad amp. it all depends on what you want your sound to be like. if you want mild get it. if you get it and want more you can always upgrade eventually.

the type r only needs 1 cf max air space. my box is tiny. i have it in the side fender well. it was kind of expensive. but its not big. im going to get a bigger box made and take up more space. haha. im so worried about anything touching my sub so i dont even use my hatch anymore.

The box that is recommended for the Type R isn't THAT much larger than the S. You are already losing a decent amount of trunk space just by going with a standard square box anyway. The extra inch or two per side that the Type R box would require wouldn't kill you...especially to get a better sub with better power handling. Also, make sure you go sealed...the required box is always smaller than ported.

2011TCfrenzy
09-27-2011, 09:07 PM
Rotz- okay the wire kit u linked looks good butt i dont know if i should go for that one or the one Cody 2005 suggested :/ and as for the box i wanted a sealed one.. And the sub you linked looks like a steal!! haha ill probably end up getting that sub for sure! lol.

2011TCfrenzy
09-27-2011, 09:11 PM
Biglilsteve - now that i've found a type R sub for about the same price as a type S ill end up getting it im sure. but i want the cheapest smallest box possible for the Type R, because thats my dads big worry about me getting a sub is because it'll take up most my trunk space.. and does anyone know if you can sit the amplifier on top of the box or will the box rattle it too much..?

1 cubic foot sealed box: http://www.sonicelectronix.com/item_24442_Sonic-Sub-Box-1H10-1.0-Black.html
Amplifier, depending on its footprint, can be hidden underneath with the spare tire and jack. I know a great many people that attach their amp directly to the box. I personally do not because I'm paranoid and I just plain don't like the way it looks. Wiring brand won't make a huge technical difference, if you're on a strict budget cheap wires are just as good as expensive ones.

+1 on the wiring decision. Just make sure the gauge is 4 or larger...everything else is whatever.

Here's my setup. It's a 12" in a 1.25 cubic foot box. I don't really feel like I'm missing out on too much trunk space. Your box would be an inch or two smaller.

I just checked the specs for the 10" Type R...optimum sealed enclosure is .6 cubic feet gross.

You could and should go even smaller and cheaper:

okay well yeah i like the slanted box that Rotz put up, but geeze the shipping is crazy! 25$!!

Lol the one I put up has the same form as the one Rotz put up...it's just smaller to get closer to Alpine's recommended specs.

2011TCfrenzy
09-27-2011, 09:52 PM
Ohh yeah that is cheaper WOW!! and are you sure .6 cubic feet is big enough? remember im not getting the slim type R im getting the 1043D or whatever.. THIS: http://www.sonicelectronix.com/item_24186_Alpine-SWR-1043D.html?utm_source=shopzilla_cse&utm_medium=cse&utm_campaign=shopzilla_cse#tabs

Yup, go to that page you just posted a link to and click the "Features & Specs" tab. You will see the minimum enclosure volume is 0.5 and the maximum is 1.0.

And if you go to Alpine's website and pull up the owner's manual for your sub, it lists the optimum sealed enclosure as being 0.6. The closest box that sonicelectronix has to that is the one I linked to above which is 0.7. It should be very good since it is almost right in the middle of 0.5 and 1.0.

can you now help me find an amplifier that will power the sub best in the .6 cubic ft box and that has a bass/gain remote, because id like to have it. and at a fair price. and i want it to last a long time so its gotta have a good cooling system and not break anytime soon and if its a known brand that'd be great.

too bad you didn't still need a type r and a sub box, im getting a new box made friday and then i woln't need it anymore. its an awesome box, fiberglass fits in finderwell, .88 cubic feet air space. black carpet to match oem carpet. the only thing that sucks is the sub hits so hard i have to strap it down. the box only weighs 6 lbs and obviously the sub ways quite a bit more. haha. you have a 2nd gen duh, never mind.
