i just got a square kicker in a trade. On the magnet it says SL7 but it dont say on the front so im not sure if its an L7 or not. and it doesnt say rated power on it so i was wandering how much power i should run to it and if i should run it sealed or ported?
how do i post pics on here and ill get a couple up. right now i have it bridged on an amp @ 8 ohms because if i bridge it @ 2 ohms i think it will kill the amp. dont know how much power its getting but my amp barely moves it. the amp is rated @300x2 @ 4ohms 500x2 @2 ohms.
Im not sure what version of the L7 you may have, but those Subwoofers can handle 750-1000 Watts RMS depending on the model. If your actually running the amplifier at 8Ohms, I can't even manage what little amount of Watts RMS your sending so im not surprised that it is hardly moving.
Also, in order to post pictures, you will need to upload your pictures on photobucket. Then, you will click on the "Link" option above and paste the URL of your picture and click "OK".
yea i traded my power acoustic 6x9 for it cuz they wouldnt fit in my talon. would i get more power to it if i ran it off 1 channel @ 2 ohms cuz i cant bridge it at 2 or can i wire each coil indipendently to each channel. is it an l7
2 x 300 Watts RMS at 4 Ohms 2 x 500 Watts MAX at 2 Ohms 2000 Watts Bridged Power at 4 Ohms
I honesty have never seen such BS specs for an amplifier ever in my life. Even the service manual says the same specs. There is no way possible this amplifier puts out this much Watts...
Since you have the DVC 4 Ohm version, I would suggest wiring each VC on it's own channel to keep it at a 4 Ohm Load. It's the best way to get the most of what ever power is coming off that amplifier. However, I woudl suggest looking into a more power amplifier if you intend to use this subwoofer.
That Legacy amp has two 15 amp fuses in the pictures. Being a low budget class AB amp I would not expect anything above 60% efficiency.
That being the case, I would say this amp probably starts clipping around ~200 watts RMS in 4-ohm bridged mode. Which means at 8-ohms you are probably gonna get no more than 100 watts RMS on a good day.
I will vouch for the AQ1200D, although I am not a fan of their recent price changes. They bumped the AQ1200D up to $269. For $30 more you can get one of crescendos new Bass Clef Series amps, the BC2000 which benches somewhere around 1100-1200 watts @ 2-ohms. Might be a bit overkill but for $30 I would probably pay for the headroom.
my legacy amp has 2 20 amp fuses which i found the ratings hard to belive cuz my 200 watt fausgate has a 30 amp fuse lol. i just posted my 15's on craigslist so hopefully i get a buyer. but i need a good capable amp for less than 200$
i would try and get one of these probably hfi2000d or jbl but think it would underpower slightly
my odd rule of thumb is whatever fuses add up to add a zero this gives you watts rms amp will do before popping fuses so take 75 percent of that should give you what ull most likely get outta daily driven
I was actually going to recommend looking for a Hifonics amp. From what I know the lower models are OVER RATED but it's hard to find a cheaper out that does what it can. I would look around for a used one from a good, reputable seller.
i actually borrowed a sub from my cousin so i was able to bridge them both for a 4 ohm load and it sounds a lot better for now till i can get the right amp. but i was wandering if ild be able to bridge that legacy and my fausgate rf 200.2 together to get a lil more boost? if i can how would i wire them 2gether?
If anything, I would just suggest installing this amplifier at 2 Ohms on the Kicker and take off the Legacy amplifier if you REALLY wanted to use it. Once again, I would preffer it if you would wait until you could power the Kicker Subwoofer properly to prevent anything from breaking.
when i looked up the specs for my fausgate amp it said 50 watts x2 @ 4 ohms 100x2 @ 2 ohms and 200 x 1 @ 4 ohms. the other sub is a really oldschool sony explode. way before walmart started selling them. its a dual 4 ohm as well. it's 1 with the metal deal sticking up from the center.
I can't believe my eyes!! DO NOT run multiple channels to 1 sub. That is the stupidest thing I have ever heard. Good way to blow that sub and prolly take the amp with it. It will also b more distorted and less output cuz the channels will cancel eachother out. Even if both channels receive the same signal, they r never pushing the xact same watts or signal. Wire it parallel to a 2 ohm load and run it from 1 channnel of whatever amp u r using now. U ain't pushin nowhere neer max for the sub, but ffr, I would suggest not giving it more than 500 wrms if u plan to enjoy it for any length of time. Or blow its pisss out and buy better ones. I believe that is what others here r trying to get u to do by running two ch. To 1 sub
i wasnt planning on running 2 channels thats y i borrowed that other sub from my cousin so i could bridge @ 4 ohms. but tomorrow im trading my old subs for the kenwood amp and im goin to give that other sub back to my cousin and just run the l7 for now.

Wasnt trying to sound like an azzhole.
Look first off,never mix subs,never run one sub off 2 different amps. If you are set on running that old beat up Keeker then get a proper enclosure for it and get a decent amp that does 500-1000wrms at 2ohms. Set the gain correctly and thats it. Dont touch the bass boost or anything like that cuz then we will have another "blew my l7 thread" and no one wants that.
naw it had good connections gain was up a lil over half way sub was at 2 ohm bass nobb on amp was only at a 1/4 way up it was sounding nice then all of a sudden there was no bass. and the amp wouldnt turn on. fuse under my hood is still clean and good. and my other amps were still working when i hooked them up. so it shoulda been good. plus i dont see an amp with 2 30 amp fuses rating at 900 watts constant

Well Kenwoods are known to be overrated and not that great in the first place so it could have just been the amp. But the gain should be set to match your head units output,not just set to what sounds good. If I were you I would just find a nice used amp or just buy a new one. What is your budget for an amp?
Looks like I got here too late. I have a friend with the same Kenwood amplifier. I was going to say that I could get it bench tested to see the real numbers, but now seeing that it is blown, what's the point?
It wasnt blown i hooked up 3 other amps an didnt get power the little washer actually fell out of the fuse holder so the copper pieces that hold the fuse werent staying together tight.the amp is still good thankfull for that i was starting to feel ripped off. the guy i traded was a good dude and was going to give me back my subs if we couldnt get the amp to work.@ joe s if u can still get it bench tested and see what it actually runs at that would be cool ild like to know.
The last number in the series is pretty much a version number from what I can see. So ASSUMING Kenwood makes improvements when releasing a new version... the 9104D should make equal to or greater power than the 9103D. Lol... thats how I look at it anyway.
it's the 9104d. ive heard they shrunk the newest model and that its not as good as the older ones. but thats only hearsay from one person. does it cost $ to get an amp bench tested or will audio shops do it for free if they think ure goin to buy summin from them. also does anybody know of a decent pair of shallow mount 6x9 i could find on ebay or amazon for $40 or less?
is there anything u can put on subs to condition them? if i run this sub sealed how big of a box should i use? currently running ported but listen to a variety of music and there's some it dont sound real good.
