A rhombus.
A parallel slope to 2 is 2. A perpendicular slope to 2 is (-1/2).
A trapezoid has 2 parallel sides and 2 that are not.
No but a cylinder does have 2 parallel bases
A square has 2 parallel sides!! You dumb dumb!
The problem you have there is that your sub woofer needs both coils wired and your options with that setup is either 2 ohms or 8 ohms depending on if you wire the sub itself in series or parallel. If you use a second sub like the first one and wire both subs in parallel and then wire the two subs in series you can achieve 4 ohms. You could also wire the subs in series ( 8 ohms each ) and then wire them in parallel to achieve the overall 4 ohms.
If you wire all 4 coils parallel, you get 1 ohm (mono).
I think if you have 2 subs, you have to wire them in parallel so they are both loaded to 4 ohms, then the amplifier will see a 2 ohm load. what amp are yu using? im planning on getting a 2ohm stable class d mono amplifier for my 4 ohm DVC Subs. You need to wire both positives to one positive input and both negatives to one negative input for parallel wiring. That's what ive learned. Since your amplifier is stable at 2 ohms, you shud get a lot of power.
yes but make sure the rms power for each is the same or close at 2 ohms and wire both subs in series-parallel
You get more power by wiring the speakers in parallel, but you need to verify that the amplifier can handle that configuration or you may blow the amp.
Yes, just make sure your amp can run at 2 ohms and you're fine.
4 gauge
How much power can the subs take in terms of RMS wattage? You can either wire them to a 4 ohm load where they will each see 125 watts, or to a 1 ohm load where they each get 250 watts. Rockford Fosgate supplies a very useful feature for showing how to wire the subs for the impedance that you want: http://www.rockfordfosgate.com/rftech/woofer_wizard.asp
4 Ohm subs wired in series gives an impedance of 8 Ohms. 2 4 Ohm subs wired in series, wired with an 8 Ohm sub in parallel gives you a final impedance of 4 Ohms. Speakers wired in series raise impedance, speakers wired in parallel lower impedance.
Yes you could do that but to keep from blowing out your subs you're probably going to have to turn your gain down on your amps. Also keep in mind if you wire these parallel you'll be at 2 ohms so your gain will probably need to be closer to the minimum setting than the max.
The final impedance would be 4 ohms.
make sure amp remote wire is connected to p.cont wire and not power ant wire on the radio
