hey, first off this is my frist post so let me know anything i should know, i appreciate any and all help given anyway here we go
i bought 2 12'' volfenhag subs and 1 1600 watt amp also volfenhag. i have heard mostly good things about the volfenhags but wanted some more opinions. i mainly bought them for there bright red color which will match perfectly with my truck. i just wanted to know the best way to install them, what wires to use fuses battery alternator ect. also what is the difference in 2ohm or 4ohm or 8 ohm and how should i run mine. i am gonna make a sealed box for the 2 12s they have these specs

500 Watts RMS Power
Dual Voice Coils
Aluminum Cone
Rubber Surround
Coated Tinsel leads
Double Magnet Structure
Oversized Vented 4- Layer Voice Coil
Bumped T-Yoke
Double Damper
Gold Plated Spring Loaded Terminals
Aluminum Die-Cast Basket
Recommended Sealed Enclosure 1.25 Cubic Feet
Model: ZX-4712DVX
.: Fs: 30Hz
.: Qts: 0.526
.: Qes: 0.614
.: Qms: 7.698
.: Vas: 56 L
.: Efficienct (1W/1m): 89.5 dB
.: Sd: 0.0491 m
.: Dual 4 Ohm Voice Coils
.: For 2/4/8 Ohm Operation
.: 500 W RMS / 1000 W Peak Each
.: Mounting Depth 160 mm
.: Hole Diameter 282 mm]
if more information is needed please let me know i am in no hurry to install this but want to do it right the first time. eventually i am going to add 2 15s but this is it for now thanks for the help Eric

Well, V-hag is out there and a player at some level, but some love em, others find them very unsatisfactory. If used as designed, think you will have decent results.
Since the amp is 320 x 2 @ 2 ohms, easiest way to wire them is make each sub a 2 ohm load. (parallel wire each coil to mating coil) and run in 2 channel mode, 1 sub per channel.
The other option is to bridge the amp to mono for ~640 watts and run the subs in a series/parallel configuration so you get a net 4 ohms to the single bridged amp. This is a bit more complex for a beginner. But we can give you diagrams on how to wire either way.
When installing this amp, use a #4 gage power wire and ground. (MIN.) I say minimum as you may want to add a mid/high amp later. If so, drop to #2 gage wiring here.
Also, this amp will definitely pull some juice from your electricals. I did not note the vehicle you are installing all this into, but the amp alone will draw over 60A. of current when you crank it up. If this is a small car and a tiny ALT/BAT., electrical issues and upgrades may be in the future. If you get severe light dimming at night, there is a problem to correct ASAP.
Often, an 80A ALT will try to keep up, but it may not. If we use a higher CCA rated BAT (Say 800+ CCA rating) you may get by. If there is still a lot of light dimming at low RPM, adding larger power feed wires (#4 wire) between ALT/BAT, BAT/GND and a 2nd grounding strap might help. If dimming is still a problem, then a HO ALT is your last upgrade.
Finally, the sub specs say 1.25 cf sealed right? That should be the inner airspace of the chamber. It is better to use a divider here to give strength to the box and if one woofer should go out, the other will still be OK. If you do not use a divider and 1 sub dies, the box is now 2.50 cf for 1 sub and it will usually die soon as well. (too large a box to support the backpressure needs of a given sub.
Hope that spawns some additional questions,
Swez

ok i uderstand most of that some a lil bit confused but the wiring diagrams should deffinitly help if you wanna e-mail them to me that would be great z28camaro3@hotmail.com
also its going in a 1991 s-10 blazer 2 dr with a 4.3 v6 and auto trans
Thanx Eric

There are several websites that give wiring diagrams for various woofer/load wiring options. Here are 2 that most people find useful:
1. http://www.jlaudio.com/tutorials/wiring/index.html#2dvcsp
2. http://www.rockfordfosgate.com/rftech/wiringwizard.asp?WoofQty=2+woofers&WoofImp=Dual+Voice+Coil+-+4+ohms+x+2&image.x=15&image.y=5 (wiring option #2, 4 ohms load)
