Default Need help!

I'm trying to figure out how my subs are wired, because I don't think they are wired correctly or at 4 ohms which I need to get 1000 watts out of my amp. they are both 4 ohm cvr kicker 12" subs. I tried uploading a video but it's not working any help would be appreciated

can I rewire them with just some 14 gauge speaker wire? or do I need something better

14ga should be fine.

It looks like the subs both have dual voice coils.
I am assuming each coil is rated at 4ohms also.

Normally, lowering the impedance load to the amp GAINS power.
Parallel wiring lowers impedances(Ohms) - gains power
Series raises impedances - drops power

To get more power run them in parallel. Make sure your amp is compatable with a 1 or 2 ohm load though. This guide should help. Remember for parallel, wire all negatives to negatives and positives to positives

This is for a 1ohm load(make sure amp is compatiable) this will give you the most power if your amp is stable at 1ohm

This is for a 4ohm load(it will give you the least power) but almost all amps are stable at this load

Can you tell me what kind of amp you have to check?

i have a 2000 f150 and i want to install an amplifier i got from my buddy. But he doesnt have the wires or a set of instructions. Im going to get a wire kit tmrw but i was wondering if anyone can give me instructions for the installation that would be great! By the way the Amplifier is 1000 watts

I have a crunch 1000.2, yes it is stable at 1 ohms but it says it only puts out 250watts at 1ohm. it says it puts out 500watts at 2ohm an 1000watts at 4 ohm.

first you need to disconnect your battery. second take everything out an make sure you have enough speaker wire, power wire (red), ground wire (brown), remote wire (thin blue), and rcas. make sure you have a good spot to mount everything, amp has enough space so it doesn't get hot an subs. time for the install, take the fuse out the power wire an place it aside. run your power wire through a fire wall, then in your after market radio hook the remote (blue) wire to the remote wire on the wiring harness. also plug in your rcas while your radio is out. run those to wherever your gonna have your amp, be sure to tuck then out if sight an no where we're they will be accidentally pulled like under the running board right when you open the door. but run your rcas on the passenger side an everything else on the driver side. some people get a whining noise when they run there rcas an power wires together on the same side. so connect the remote, power, rcas an now your ground wire to the amp. now make sure you have a good place to connect the ground wire, it needs to be a metal surface clear of paint. then connect your speakers wires according to how your running your subs. then your all set, hook your battery up turn ignition off then off then put in your fuse and your all set!

Only look at RMS wattage. The peak power is pretty much a made up number. RMS wattage is the true continuous output of the amplifier.

I looked up your amp and here are the specs.

4 ohms: 125 watts x 2 chan.
2 ohms: 250 watts x 2 chan.
Bridged, 4 ohms: 500 watts x 1 chan.

You could either run each sub off a seperate channel. Thus running each sub at 2ohms each.

Or you could wire the subs together in series to get the 4ohm x 1 load. You would then need to wire each voice coil in parallel on each sub. Then series them together.

I wasnt sure if that was rms peak or what. so which one do I need to wire it up like to achieve the 4ohm at 1 load, the 4 ohm diagram you listed above?
