Best Amp For 2 12" Kicker Solo Barics L7's

Hi, I was wondering what you guys recommend for powering up 2 12" Kicker Solo Barics L7's 4 Ohm. I have them on my 02 Trans Am.I had originally bought a Pyramid with 1,800 watts and I swear that the amp would switch from the green light to the overload red in about 15 secondsa of the subs thumping. So I just gave the amp to my friend. I need an amp that really delivers the advertised power rating. Any suggestions are greatly appreciated. I kept the stock unit and the speakers, I just added the subwoofers via a Hi/Lo converter. Thanks, Hector

the ohms are kind of complicated to explain, look up ohms law and read about it once u got it it is real easy. i can explain it better in person, me writing here is just going to confuse u.
as for amp
u will need a amp the either puts out its most at either 4ohms bridged or 1 ohm bridged

the word "dual" means dual voice coils. a 2 ohm woofer also produces less power than a 4 ohm because a 4 ohm woofer has 2 stacked magnets on it versus just one. Also, FORGET max power, it is useless as far as looking for an amp goes. RMS is where the power is. If i am not mistaken those subs are something like 75-750 watts rms.....so without blowing thing, and making them as impressive as possible.....i'd go with TWO amps instead of one......put two Alpine MRD-M1005 amps in there. They are mono amps so u will have one running to each sub. They are about $550 a piece and are one of the best mono subwoofer amps out there. Make sure u don't have any other amps running though, because that maxes out ur stock alternator definitely. Another thing, when you install them, on the back of the subs you will see four posts, two negative and two positive. To hook that all up correctly you have to parallel wire them, that is special to 4 ohm woofers so i didn't know if you knew that or not. Good luck man!

unless i am reading this wrong, what u wrote is not correct, it has nothing to do with the magnets of a sub....the ohms are the resistance of a speaker. also a lower ohms will suck mre power from your amp than a higher one.
lets say u have a 2 ohm sub and a 8ohm sub. if u connect it to a amp the produce 100 watts at 4 ohms.....at 2 ohms u are likley to see close to 200 watss out of that amp and at 8 ohms u will see like 50 watts.
those #'s are definate i am just giving a example. but the lower the ohm the more power it will suck from the amp.
the key is to find a amp to match the ohms your subs have.
in his case it is either a 1 ohm or a 4 ohm bridged amp. about 300-500watts per sub is plenty.
i had 4 L7's in my grand cherokee running of 2 kicker zr1000 amps. it was too much, i took one off and only left one too all of them which gave each one about 350watts and it sounded nuts, didn't even notice a difference when i removed the other amp.

oh yeah, and to explain rms to you, it is the amount of continuous power that an amplifier puts out at any given time. So when you see a rating on an amp for "max rms", that is the max amount of continuous power that that amp is capable of putting out. Also, all amps have ratings for 4 ohms and 2 ohms.......since your subs are 4 ohm subs...pay attention to the 4 ohm ratings. Also, if you don't like the idea of mono amps, the best idea for a 2 channel amp for those is a treo SSX75.4. That is the most powerful 2 channel amp on the market right now.

sexyvic1, qwikz28, skindog39,
Thank you guys for your input. I understand there may not be such a thing as the best speaker out there, but are these speakers a good start to an awesome sounding bass? So the 4 ohm draw less power from the amp, is that a good thing or a bad thing? Once again thanks for helping me out!!!!

alright, hey again. I for one love kicker's line. Those subs are AWESOME. You will be very happy with them. I'm not so sure on the mtx aps....i don't trust them......and jbl can be good.........i'd do the two mono amps though from alpine, you won't regret it....good luck!

I'm a manager in Car audio at one of the big two. As someone said previously, just try to put between 250 and 350 watts RMS to each sub. That would put you at 500 to 600 watts RMS at 4ohms. All you need to do is go out and find an amp that says 500 or 600 watts RMS @ 4ohms. And there is no such thing as someone running subs "not liking" a mono amp. A mono amp Class D amp is preferred if you are running subwoofers because they are only meant to pass low frequencies. Either one is fine. If you do buy a 2-channel amp, bridge the amp which means combine channel one and channel two together. You will have to wire each sub in parralel and then run the two subs together in series.
Translation:
Run + to + and - to - on each sub. That puts each sub in parallel.
Run the + and - for each sub on either voice coil to the + and - on the box. + to+ and - to -. All that does is wire the sub to the box terminals.
Then run the + from channel 1 to the + on the first sub, the first sub - to the second sub + and the second sub - to the channel 2 -. That will run the subs in series.
have fun.
BTW: go on ebay and pick up a Rockford Fosgate 1001bd. Newer amp or older amp makes no difference. That particular amp is badass and is just as good as the new ones. When it comes to subs, for the most part, as long as you stick with a quality name brand, an amp is an amp is an amp. Whether it is Alpine, Fosgate, JL Audio, Kenwood or Kicker is not that big of a deal. Now when your looking for an amp for your interior speakers, that is a different story.
Just make sure the amp says 600watts RMSx1@4ohms and your good to go. And don't bother with two amps, thats rediculous and unneccesary unless it is a very powerful sub like an Alpine Type X or JLW7. Why would you need two amps for two subs when one guy was using one amp for four of the same subs your buying. It looks "cooler"/more complicated with the power and ground distribution blocks but thats about it. It will not give you any advantage over sound or performance. I would also recommend a capacitor for an amp over 500watts RMS. A one-farad cap is fine. It will keep the power consistant and also help your alt. and battery from browning out. PM if you have anymore questions.

SStolen,
Damn, you really seem to know your stuff. I really appreciate all the help that you have given me, and also for taking your precious time and writing all of these for me to understand. So then it is not necessary for me to meet the 750 RMS requirements that the subs packaging say in orrder for them to pound? Once again thank you very much.
Peace & Respect, Hector
