Help!
HI guys im new to the site. i have a few questions that you will probably laugh at but here it goes. i was wondering if some one could explain the difference between single and dual voice coils and 2 and 4 ohm subs. i am looking at doing a 3 or 4 10" set up in my truck and dont know what i should be buying. im looking for huge bass but clarity at milder volumes.

How many replies do you expect at 4 a.m.? Anyways, this is a really expansive question you've asked. How much space are you willing to devote to 3-4 subs in a truck? Do you already have an amp(s)?
To answer your question subwoofers can have one, two, or even four voice coils. Each coil can have a resistance from one ohm to eight ohms (For Example: a single four ohm subwoofer, a dual two ohm, a dual four ohm or a quad one ohm). Each voice coil can be wired in series / parallel to ahcieve a desired load. You can take four 4 ohm subwoofers and wire it in a series/parallel configuration to achieve a final two ohm load. You can wire one sub to one amp each or two subs to one amp etc.
Since your final load is more important than how the woofers are wired, I'd recommend that you decide how many subwoofers you want to install, then shop around for a sub that is best for you. Then make sure it can be wired to a load that is suitable for your choice of amp(s). If you don't already have an amp then you can choose one or more that suits your subwoofers' final load.

Well im willing to devote my back seat for this project. yeah 4am isnt a good time to ask question i was just over excited. so what your saying is to start with Subs and build the box for proper airspace and then go with amps. and my goal is to get down to 2ohms at the amps i was thinking of 2 amps and 4 10"s i was looking at hifi connections the other night they seem to have good prices

like i say i dont know anything i just like the way they sound so this is going to be a learning process i honestly couldnt tell you what was better out of 2 subs i know the guy at the store will tell me the one with the big price tag is the best

Well keep in mind, subs are going to sound a lot different in your car than on a display wall. What brand and model of subs were you looking at, and what does your shop carry, we can give you advice based on what your shop carries.

i wanted to do JLW7's but i was told that would be nutz and expensive so now im at a loss i like clarion kicker phionex gold and rockford but i dont really have anything to compare them too i was also told that 10"s are a lil punchier then 12"s are.
