Rep Power: 0

guys,

its my first time to connect a sub to my stereo

i have this:
*Dual 4 ohm 12 inch sub
* 2-channel bridgeable amp

what is the best wiring connection?

1- bridged amp to a series DVC
2- bridged amp to a parallel DVC
3- bridged amp to a single coil
4- 1 channel of amp to each dvc coil


thanx

if you gotta amp thatll regulate at 2ohms, wire that single DVC in parallel to get 2ohms.

Most amps aren't stable at 2 ohms bridged, which leaves you with option 1 and 4 [I just don't like #3].

If your amp is stable at 2 ohms bridged, definitely do option 2, else, option 1 and 4 should sound the same, although probably not using the full potential of your amplifier [assuming it's the typical 2 ohms stereo stable/4 ohms bridged stable].

i think my amp cant do 2 ohms, i'll just do number one

whats the advantage of having a higher resistance? say 2 ohms?

2 ohms is lower resistance, which means there is more current going through your amp than it can handle, so you'd always be blowing fuses on your amp or eventually frying your amp. If you've got the chance to return it, i'd get a mono amp that could handle 2 ohms, or get that same sub but get it with dual 2ohms voice coils and wire it in series to give you 4ohms.

The lower the ohms, the higher the current will be. The higher the current is, the more power in watts is output.

Take this amp:
100x2 @ 4 ohms
200x2 @ 2 ohms
400x1 @ 4 ohms (bridged)

So if you have a 2 ohm setup hooked to that amp while bridged you have half as much ohms as suggested. That means the amp is going to have a lot more current running through it. Therefor it will also put out much more power. You just turned the 400 watt amp into an 800 watt amp. Generally amps will go into protection or blow fuses, other times they just burn themselves up.

Now what you will have to do is wire the subs in series so that you end up w/ 8 ohms. In this case you get half the rated power of the rating at 4 ohms bridged. This is because the ohms is twice as much, so current is half of what it could be, and power is cut in half.

This is why you really can't take full advantage of all the power the amp can put out w/ this sub combination.
