new to the site, glad i found it, my car isnt much to look nor does it have massive amounts of HP, but i like loud music. and yes i should get a bigger engine. but anyway, i have two 10" Xsite subs that are 600w (RMS) with a MAaudio hardcore amp, model HK898 1200w, read anywhere and that is the rms. i cant find much info on the subs. weird brand. voice coils were said to be dual 2, 4, or 8 ohm operation. thats what the book said. can anyone find info and suggest how to hook them up, and what to put them in. right now they are in seperate vented boxes. i think they are too big for the subs. i want a well box. any suggestions would be appreciated. thanks.

 

There's no way you could wire for 2, 4, and 8 with only two coils. If the subs were DVC with 4 ohm coils that would give you the possibility of running either 2 or 8 ohms a speaker, which you could then take to either 4 ohms or 1 ohm by running two subs. Take a multimeter to a voice coil and find out.

I have no knowledge of either the sub or the amp but I’m sure someone here will.

As for the box, what do you mean ported with a vent style port (rectangle)? Also, are you looking at building your own box in the future to replace what you’re running now? There’s an ongoing thread by Phlaxus with dimensions for a larger ported box and there are two stickes on the top of the board for building your own box (one for MDF and one for fiberglass).

 

Sometimes DVC subs will be described as being able to have a 2, 4, or 8 ohm load. If it's got dual 4 ohm coils, you can run 1 coil on each channel of an amp, which gives a 4 ohm load on each. It's a bit deceiving, but some companies don't care as long as it generates sales.

You should be able to find information on your subs here:

It's one of a million low quality chinese made brands.

 

i believe they are dual 4 ohm. and for being an "off" brand these things pound and hit the low notes pretty good. vented with a rectangle slot that goes into the box. they work ok but i want my backseat and some cargo space back. i dont know if i want to build one or buy one. i was lookin on ebay for custom boxes. i would buy one but i dont know how well they will fit, even tho they are "custom". maybe someone can give me an opinion on some of those boxes. the amp you can look up at maaudio.com.

 

It doesn't take a lot of quality to make a subwoofer loud. A lot of x-max, and a voice coil that's strong enough to handle a lot of thermal power is all it takes to make a loud woofer. Use some cheap heavy cone material and an underpowered motor assembly to raise the Qts, and it'll also go very deep.

However, for a woofer to remain loud after taking a pounding day in and day out requires higher quality suspension components, mainly the spider. A lot of super cheap subs use a cheap spider that loosens up, which causes a misalignment in the voice coil gap, as well as a looser suspension compliance, which can change the t/s parameters significantly.

To get good sound quality, that's when a quality low distortion motor combined with quality materials and quality construction techniques & tolerances come into play.

 

wow that is a lot of information. you definately seem to know your stuff. i know they are not high quality but they were cheap and they get the job done, now i just need the right box.

 

Jim defiantly knows his stuff. He also builds custom boxes that will fit our cars

Again, it's not very hard to build yourself a box. Right now you should focus on where you want to put it. The hatch is hands down the best place to have it, but there are alternatives (stealth boxes and the back seat). Stealth boxes are expensive, so I would rule them out in your case. You already said that you want to keep your back seat, so you're forced into using the well.

If you don't mind sacrificing box volume you can build a box that takes up half the well and then still have the ability to put items on top of it. Or you can do as most of us and just use your back seat when you want to carry stuff around and build a box that will fill the hatch. Larger boxes typically get lower/require less power. Smaller boxes are more "punchy" and can handle more power.

How are you at working with wood? How about fiberglass? Wood is defiantly easier, but fiberglass will allow you a lot more flexibility (and the ability to build a stealth box yourself if you’re willing to commit the time).

 

well with wood, i can be pretty good if i had the right tools. i dont have access to anything. i think i want the well box probably right to the the top of the hump. or close to it. i think about the medium range for those subs is a little less than 1 cu.f. i dont know have to see.
