Michael: Are you running them in 4 ohm or 2 ohm and do you know much about building a internal box by using your quarter panel area in the cargo area/

i am running a single 12" DVC in parallel so yes i am running it at a 2 ohm load. I am not quite sure of your question are you wanting to build a box molded in the side of you trunk and what size, make, etc.

This amplifier is not stable at 2 ohms. it is limited to 4 ohm loads or higher.

Well didn't look up specs but if your running 2 subs I wouldn't overrun the subs rms too much. I wouldn't put more than 1200 watts on them. Over powering even though they are underrated certain songs like jeezy will burn your subs. I am running 2 jlaudio jx1000/1 awesome amp. I blew my obsidian 18 with that amp. So they are 900 watts at 12v I'm running them at 32 hertz. Loudest system I have had. I would run 1 Rockford to two if that is 1250. I also run two batteries for the two amps. I think that is making all the difference running rf 3sixty.2 whole car is dymatted. Do 4 sealed. With the two amps. These subs sound better sealed. 4 sealed on 5000 watts will sound better than 2 ported on 5000. I do prefer my 32 hertz box but you can really see what they can do sealed. Better sq. Although the sq is flawless anyway. Best subs ever man for the money. Will eat an idmax

One that will fit into your vehicle, make sure that the box is port slotted, the bigger the better! And your amp really needs to be at least 2000Watts, and wire them at 1 ohm

For that I'll get the 2 Ohm. But you can get the 4 Ohm and Put only 2 ohm later get a 2000 watt amp and put the 4 Ohm I'll do that maybe what you think? Thus that answer your question Alex

2 ohms is always less resistance Than 4...therefore 2 ohms sound louder and hit harder

Let me tell you this,in two ohms it puts out the power ... Four ohms if you just want it to be okay.. I have it running a 4 ohm 10. Inch rockfordfosge in a sealed box and it sounds good. I also have a dual 10 inch power bass and I ran it in two ohms in a sealed box and it hit real hard and low. But I'm not sll that into bass,I like to hear my highs and mids so I kept the fosgage in the trunk instead of the power bass.

If you are going to use a single 12" it is better if you get the dual 2 ohm as this will come down to 1 ohm and most amps would be 1 ohm stable in this power braket. 1000 rms at 1 ohm is good enough to shake this beast. Doesnt need more.i have used 2.5 and 3 cube boxes. 3 is better. It is not a low frequency sub so dont tune too low. 38 hz is lowest i would go. It is loud though !!! Excellent value for your money. Just remember to break it in well before you turn it up.

Ummmmm.... 8 ohms. Lol. If it has an 8 ohm load, then it's 8 ohms. You can wire it at either 8 ohms or 2 ohms. Zero benefit wiring it at 8ohms....I have mine wired at 2ohms and 1200 RMS watts driving it in a ported box.

I run a hifonics 500rms x 2 @ 2 ohms for 4 speakers and ran that for at least 5 yrs and have yet to have any issues with them. Ive overheated the amp a few times(more than likely due to poor design) but the speakers have handled it just fine and I run them hard often.Just bought a new truck and plan on installing a set in it as they have never given me issues.

This sub can only be wired for 2 or 8 ohms since there are two 4 ohm coils. If they are series it will be 8 ohms and if they are paralleled it will be 2 ohms. The directions for this sub recommends a 1.75ft^3 for a ported enclosure ( with a 3" port 4.76" long) or a .75ft^3 sealed enclosure. I would have to know your boxes port size to comment on the enclosure you have.

Well............I have a little 100W inverter I put in the cig lighter. I plugged in the tranmitter setting the Freq to 103.1. I plugged my I-pod into the trasmitter. I turned on my little sony walkman to that Freq, and wahlah. Perfect reception. Started my Chev Luv thinking of Alternator noise, or some kind of engine interference, but...............worked perfect. In my setup no noise. Let me know if there is anything else I can do for you.

That's chillin'. I'm running mine at 420watts at 2ohm. There is a general consensus that powering any speaker at 80% will ensure longevity and durability.

Amp wants a 4 ohm load, and performs best at that resistance. How many terminals does your sub have (I presume 2) and what are the drivers' impedance? Whatever you do, you MUST attain a 4 ohm NET resistance

I'm using a old four channel that can withstand the 2 ohm load so you can look for a cheap one on amazon or sonicelectronx that can hold 2ohms but remember to break them in first

After years of advancing in car audio i would never use a Farrad battery again. Not even on a small build, IMO its a waste of $ and time. Upgrade main battery with the big 3 0 gauge used for best performance on a small system.I run a HO alt, 4 batteries, 12 fuses, 100+ feet of 0 gauge OFC wire, I have a couple grand in electrical system.

Yes these are 2 ohm, and awesome speakers. I have friends with different name brands in their cars and tell me they want to buy some jbl's now that they've heard mine and I only have a stock head unit
