Will this work and present a mono output at 4 ohm to my amplifier?
Okay, so first off here are the stats on what I have:
2 Alpine Type R 1242 DVC 4 ohm subs. Each is rated at 500 RMS, so this is what I would like to run them at.
Hifonics zxi1010 amplifier: (This amplifier can run either 1 or 2 channels)
4 ohms: 250 watts x 2 chan.
2 ohms: 500 watts x 2 chan.
Bridged, 4 ohms: 1000 watts x 1 chan.
I want to run this amp at the last option, bridged 4 ohms 1000 watts x 1 channel.
However, I took it to get installed, and when I picked it up, the company had wired it to 250 watts x 2 channel at 4 ohm. So, it is pretty much running at half what it should be, and I want to wire this correctly.
Here is the wiring diagram that I want to do
However, I find this quite confusing once I add in the sub enclosure terminals and my amplifier. Did I hook up my Dual voice coil subs correctly? This person did what I want to do, but I still cannot grasp it when I transfer it to my amplifier and enclosure.
Will I only be running wires from ONE channel on the amp? Or are they bridged internally?
Help is GREATLY appreciated
You can do it either way... If you bridge it to use only one channel thus ending up with 1000 watts to split between both subs, you will need to end up with a 4-ohm load at the amp. This is crucial so you do not harm the amp. To achieve this wire it like this: http://a248.e.akamai.net/pix.crutchf...4-ohm_mono.jpg This image shows a mono amp but you will do it the same way just wiring it as ur owners manual says to in order to correctly bridge it.
You can also wire it as 2 separate channels at a 2-ohm load giving you 2 channels at 500watts a piece for each sub. To accomplish this do it like this: http://a248.e.akamai.net/pix.crutchf..._4-ohm_2ch.jpg
it would be a parallel/series circuit--- wire both subs so that both are 2ohms, and have a negative and positive wire for each sub. Connect the positive wire of one sub to the negative wire for the other sub, and connect the other 2 wires you have left to the corrct terminals on the amp(usually the positive of channel 1, and the negative of channel 2, but confirm it before doing it). And you will have a 4 ohm load on the amp with 1000watt rms...
wiring, I may try to draw out a diagram of what youre saying to help me understand.
And would I have to drill a hole in the enclosure inside on the wall that separates the subs so I can run the wire like you said?
series (thus producing an 8-ohm load on each sub). When you wire both subs in parallel, it yields a final 4 ohm load at the amp.
The other option is to wire the voice coils of each sub in parallel (positive to positive and negative to negative), producing a 2 ohm load for each sub. Then, wire both subs in series to the amp yielding a final 4 ohm load. Amp(+) to sub1(+), sub1(-) to sub2(+), sub2(-) to amp(-). I don't feel like trying to sketch something out, but hopefully you can picture this.
Either option will work. Both yield the same end result and are identical in terms of physics. Ask if you need more explanation.
Edit: scratch that (your diagram probably wont work). I'm not sure what your amp is like (I'd have to find the manual), but your hand-drawn diagram is probably not bridging the amp. As soundman said, most amps run bridged with one wire connected to channel 1 positive and one connected to channel 2 negative. But, I'd have to browse your manual to be sure.
I just looked at the manual for your amp. What you would want to do is wire the subs as shown in the first image you posted (from the12volt) and then connect the leads to channel 1 positive and channel 2 negative (nothing will be connected to either channel 1 negative or channel 2 positive on your amp). Check page three of the manual. You don't want to drill any holes in the enclosure. Just connect all the wires from the speaker terminals on the enclosure.
i was trying to post, and my computer locked up...i guess it didn't like what i had to say...
anyways, the hookup diagram for your amp is on page 5 of your manual, but i drew you a couple of pics of how the subs can be hooked up.
my recommended way:
applebonkers recommended way:
neither way is any better than the other, it is just a different way to do it...
thanks everyone for the help, got it up and running
