Hi i just put on my xmas list a kicker l7 12" and i didnt ask for a box because if my parents get the box they'll probably get a **** box so im gonna buy my own box and amp for it and want to know which kind of box and how big and what amp so i can get the most out of this amazing sub i want lots of power please give me reccomendations

i have a 91 camaro

thank you

 

and i dont know the difference between the 4 ohm or 2 ohm l7 12s and please tell me which one i should get

 

2 Ohm is better because the lower the ohm the more base you are going to get out of your subs that is why it is best to get a 4 channel amp and subs that can push 2 ohms.

 

With the solo baric kicker L7's you probably want to look at a 1500-2000 watt 4 channel amp that is my personal opinion if you want lost of power.

 

this looks good, just get the box and sub from crutchfield, MDF (medium Density fiberboard) box, those are nice.

lower imped does not change the bass. you can get either the 2 or 4 ohm, you just have to match the amp to it. do not get a 4 channel amp for one sub. i wouldnt even do it for two subs probably. if you get the dual 2 ohm sub, get a two channel amp. if you get the dual 4 ohm, get a mono amp. look for an amp that puts out 500 to 800 watts rms. for a 2-channel, that will be what it puts out at 4 ohms bridged. for the mono, its what it puts out at 2 ohms. you would be satisfied probably with something in the 500 watt range. just dont look for rated max number. it doesnt mean jack. always look for rms or continous wattage.

 

Tamu... that seems to be an old name around these boards I remember faintly. 2ohm doesnt sound any lower? Louder? I was under the impression that it draws more watts making it louder.

 

the same amplifier at 2 ohms will make more power than running at 4 ohms, the problem is that most amps wont run a 2 ohm load. to get an amp to run a 2 ohm load generally requires a really high quality amp, or a class D amp.

it has little to do with sound, the ONLY things about different impedance woofers are
1. a higher resistance sub will have a slightly tighter bass
2. the difference of impedances will give you different electrical loads.

Stick with Tamu, he's a smart dude.

definitely dont buy a 4 channel amp for that sub. I would get a decent 2 channel or mono amp that puts out about 1000 watts rms. I suggest the JBL 1200.1 for its power, price, and reliability but there are many other capable amps out there.

the lower impedence you wire to the amp the more THD (total harmonic distortion) there is. But THD is mainly audible in higher frequencies so worrying about hearing distortion when wiring to a lower load shouldnt be worried about all that much.

If i were you i would decide on the amp you want and see where it puts out its most power. If it is only 2 ohm stable and no less, then you will want the dual 4 ohm L7 so you can wire the VCs in parralel and yield a 2 ohm load on the amp.

As for buying a box i wouldnt do that either. Prefabricated boxes are generally not built very well at all. The sub enclosure itself makes up 90% of the sound and output. No matter how good your sub/amp combo is, with a crappy install it wont sound good. I would suggest building a box yourself, its very cheap and doesnt require all that much skill. This way you can make a nice ported box for the L7 (which it responds better in than sealed) and even contour it to your car if you like.

 

your right about the wattage thing red. but i dont think we were talking about the amp giving more power because it was 2 ohms, we were talking about the sub getting more bass simply because it was 2 ohms. as onebad said, alot of amps will not satisfy a 2 ohm load for very long if at all. i personally would only use the dual 4 ohms if i had a mono amp. unfortunately, most people dont relize that you need to match up the amp and subs.

there seems to be some good info in this thread, somebody could maybe learn something if they paid attention.

p.s. red... i have been on the boards for some time now (about a year and a half), but i have been quite busy of late and havent had the time to get on much. its always good talkin to you guys. i get alot of info off these boards and i try to give back as much as possible. and thanks onebad for the compliment. i can always appreciate that.

 

the reason we make them in DVC 2 and 4 is wiring configurations, has nothing to do with power, or how well the woofer will sound or not sound. I would always reccommend a mono block class d sub amp for any subwoofer. Almost all amplifiers made down don't have enought THD to hurt anything...so a Kicker KX1200, JBL 12001 or DEI1100d will work...heck, and good class D amp.

Now on the enclosure...best is to get one made for your particular vehicle, as most prefab boxes will not show the full potenial of your setup. An enclosure will make or break your system...............
