I bought these 12 inch Rockford Fosgate Power DVC which are 1000 watts RMS each. I bought these a few months before buying my car because I got a good deal on them. You should see these subs, and even more impressive, you should heat them. After hearing them hooked up on a house amp, I'm not sure if I should install them in my car. They were built for competition but I'm not really into that.

Any thoughts.....?

 

heat them = hear them

heh

 

get a crossover run the remote to your cabin, so you can turn down the gain from inside the car. So when you want them loud you can turn it up, when you just want them to sound good you can turn them down.

Or you could sell them for a pretty penny and buy like one ten or two eights.

 

I have 2 8" RF's in my car and they're the competitions as well. They sound great and they aren't over powering to the rest of my stereo. You can hear me coming, but you normally hear all the music and not just the bass. I've always been partial to having 2 subs in the car b/c it makes for a more balanced sound. If you don't want to rattle your car apart, get rid of the 12's and get some 10's or 8's in there.
Also, DO NOT PLUG YOUR SUBS INTO YOUR HOME STEREO!!! You will burn out the voice coils on them. Your subs are made to take 4 OHMS (your's are probably 2 OHMS), your home stereo pushes out 8 OHMS and it will burn out the voice coils. See, the 8 OHM speakers have a lot more range in sound than do the 4 or 2 OHM speakers, if you make a 2 OHM speaker play the same wave lengths as an 8 OHM then the voice coils will overheat and melt or just plain get damaged and sound crappy. So, take those off your stereo and stick them back in the closet till you get car audio amp to push those babies. Good luck with your stereo...and just a word of advice, loose the BOSE speakers in your new max.

 

ya but I set em up on my home amp on 4ohm connection

 

I tested my 2 10" JBL GT DVC's on my home amp (100 watts per channel and the subs are 130 rms) but...sinc ethe subs said they could be run at 8 ohms I didn't see why there would be a problem. If on the subs it said it could be run at 2, 4, or 8 ohms then I am fine right? Plus i only did it for maybe...10 minutes.

First off, I have 4 12's in my car and the lp44 for my phoenix gold so I can adjust the amount of bass from the subs seperately from the rest of the system. If you want that much bass you must upgrade your mid's and tweet's. I have all Infinity mid range speakers pushed by just the right amount of power. With this setup even though the bass is super loud it is still balanced with the rest of the system. Second the ohm rating on the back of the speakers are the amount of resistance those speakers produce. If you have a 4 ohm speaker hooked up to a 100 watt 8 ohm home stereo youll not only blow the home system by over heating it. But also by dropping the ohm load to 4 ohms youll also double the power so instead off 100 watts @ 8 ohms youll see around 200 watts @ 4 ohms. If you manage to hook up a 2 ohm load youll see aproximately 400 watts and probably the genie from not only the speakers but the home system in a few minutes ( trust me I did this and saw the smoke after about 2 minutes).

 

Hooked up 4ohm speakers to a 150w/ch Technics Home Amplifer and Click! Protection circuit on the amp kicks in and the sound processor fries and then the amp becomes a paperweight. Had the amp fixed, few months later while running normal speakers, Click! It happened again. I have now had the thing fixed 3 times and a year ago it went out again. I dont think you should try hooking up 4ohm speakers to your home amp. btw: I only had the speakers hooked up for about 5 minutes at low volume. So if you like your stereo, keep the speakers in the car. =)

 

Greyboy, do you have any idea about car audio or audio in general? Subwoofers are not made to take "ohms". Ohms are the resistance of a device. He has DVC subs(which means dual voice coil). Each coil is 4 ohms, meaning that he can wire them together into many different resistances to get the most power out of his amp. If anything it is unsafe to power for his HOME amp to be powering his sub as it is only 8 or maybe 4 ohm stable depending on his amp. Then again he might have taken this into consideration and wired his subs correctly to work with his home amp. Also, the resistance of a speaker (ohms) plays no role on what frequencies (wavelengths or range as you put it) a speaker plays. Bose systems use 1 ohm speakers. My Infinity's are 4 ohms. Do they produce different sounds?? NO!! How do home and car subs differ? How can an Adire Audio Shiva be used in the home and in the car? Please do not speak when you have no clue what you are talking about.
