Keith -
If you know "solos are very touchy", why recommend an an amp rating ABOVE the wrms rating?
AND second - you're dead wrong about impedence!

Joel - DONT BUY THIS SUB. It is D2 impedence so you will need an amp that pushes 750wrms at 4ohms. I've yet to see a quality amp that pushes that under $300. IF all you want is to push 1 L7, find one that is D4, so you can wire it down to 2ohms.

So my advice is to find an L7 w/D4 coils and purchase a zx750.1 refurbished at around $200.

If you have your heart dead set on this L7, tell me but amps that push 750wrms at 4ohms arent for low budgets.

You can also use an amp that pushes more at 1 ohm... :-)

Here is a quality built amp that pushes 1200 watts rms @4ohms for 160 bucks. You can use that sub if you want. Any class d sub woofer amp that goes down to 1 ohm and pushes 750 rms or more will work . This one pushes 1200 rms and made by zed audio ( the best car audio amplifier manufacture in the world!! ). If the wattage is to much thats what they make gain controls for!

Just goes to show, some people don't know crap about car audio or finding a good deal on quality equipment.

ehh forgot about 1ohm load...dont know wtf i was thinking

but i would not recommend that amp because 1200wrms might put a strain on your electrical system (assuming not even the big 3 is done).

Plus you have to set teh gain perfect or blown L7.

i would look for an amp than pushes near 800wrms to avoid a blown sub.

but you're rite...and looking at it my post doesnt make sense...so yeah

Jamey, which class is that amp? I saw in the manual that the driver stages run in class A mode, but nothing about the class of the actual amp. I gotta learn more about the structure of amplifiers, but bare with me. I saw the fuse ratings were 40x3, so I figured it couldn't be class A, but I have no idea.
Thanks man.

Cam that amplifier is class A . So it will pull a butt load of juice. It will work for your application though. I myself would prollybuy something like this

If you go with this brand.

Chauncey I have been into car audio almost 20 years. I Know the diffence between quality and crap. Anytime you wanna be schooled just let me know. Unlike yourself I am not trying to sell anything.

Here lets look at your kicker amps vs. the class d planet audio from the link above

PLanet Audio APD
1250 rmsx1 @ 1 ohm (@ 12volts )
thd 1 watt at 4 ohms 0.5
signal to noise 100db
frequency response 20hz-250hz

Kicker SX1250.1
1250 RMS X 1 @1 ohm (@ 13.8volts)
Thd 1 watt 4 ohms 1.5
Signal to Noise 98db
frequency response 20-200 hz

Now anytime you wanna talk amps come back here and let me teach you a few things.

Been in the game for 20years and yet still dont no what ur talking about???

My kicker amps>>>>>>>>>>>>>>>>>>>>>P.O.S. Planet Audio amp....My amp is digital that p.a amp is not..thats a huge diff right there...also that will never see 1200rms not even 1000rms..if an amp will not state rms at 4ohms bridged then its crap...Only somebody with little knowledge would not understand that...also its not a Class D amp, which means even if it did do its stated numbers(which it wont) it would not be efficient at all...in general a watt is a watt.. when buying an amp your paying for the quality of the components used to make those watts as well as the warranty, brand, ect..

for you to recommend a planet audio amp speaks volumes about ur knowledge of car audio...

Also im not always trying to sell stuff, where would you get off saying that??

"My amp is digital that p.a amp is not..thats a huge diff right there"

Well Chauncey I guess the auction listed it wrong as class d. I also guess the manufacture listed it wrong as a class d.

"if an amp will not state rms at 4ohms bridged then its crap...Only somebody with little knowledge would not understand that.."

Since you know so much about amplifiers then you should be able to do math and understand ohm loads. Do the math man ,come on look at the documents on that P.A. amplifier. The rating on that amplifier is the true Rms rating.


"when buying an amp your paying for the quality of the components used to make those watts"

You said it! Right here! Those Planet audio amps were made by Zed Audio. Right here In the USA.I bet your kicker was made in China or Korea or some other third world country.They (Zed Audio ) Only use Quality components. I Think anyone Nakamichi , Harmon Kardon , or Polk Audio hires to build there thousand dollar amps know Quality.If you don't who zed audio is then you need read this post from the link below.

"for you to recommend a planet audio amp speaks volumes about ur knowledge of car audio... "

Well Thank you! I mean I am not an Eistien by any means but since I work on amplifiers and other electronics every day all day long in a Repair shop,Well I try

Oh Chancey by the way I notice a few other items I need to mention to you.

"if an amp will not state rms at 4ohms bridged then its crap...Only somebody with little knowledge would not understand that.."

Neither that Kicker amp you have or that planet audio amp will "Bridge" You can't bridge a single channel amp. Unless you can strap 2 together.

Also you need to look up form factors on Amplifiers. Any amplifiers made in the United States has to go by Root mean square standards as listed in "UL" Rating from the Underwriters Labratories to obtain the most 'true' RMS rating.

Don't feel bad about buying those Kicker amps, those are decent mid grade amplfiers . You just got suckered in by the ever changing Car Audio world and some crafty marketing.

This guy keeps shooting himself in the foot..

"Since you know so much about amplifiers then you should be able to do math and understand ohm loads. Do the math man ,come on look at the documents on that P.A. amplifier. The rating on that amplifier is the true Rms rating."

Did the math and that first amp u posted still doesnt do what you stated it would...Until u show me a birthsheet or proof that it has been benched tested by an accredited company then :p

"Those Planet audio amps were made by Zed Audio"

I no exactly who Zed Audio are..and just like almost ever other company they have there lower lines, and Planet audio is just that a lower P.O.S. brand just because Ford makes the FordGT doesnt mean they dont make the Ford Focus as well...

"Neither that Kicker amp you have or that planet audio amp will "Bridge" You can't bridge a single channel amp. Unless you can strap 2 together."

No sh!t...again refering to the amp in the first link, u posted

"

Yeah but at what cost? Some sony amp are CEA compliant to do 1200rms...but at what cost?? High Harmonic distortion?? High Intermodulation distortion??...

From what you are telling me is that my Kicker sx1250.1 with a birthsheet that states with all channels driven will produce 1503rms@1ohm is not a better amp then that P.O.S. Planet Audio amp?? If so you need to get out of the back of that shop more...

Also neither of the amps you have posted has stated 1200rms @1ohm...neither of them..so your whole point is invald/ Thread

PS..G Irv, please stay around and learn something about car audio :-)

You know I could keep showing you spec by spec that those Planet Audio Amps will run with your kicker amp any day, but I think this is my last post on this subject.

"Did the math and that first amp u posted still doesnt do what you stated it would...Until u show me a birthsheet or proof that it has been benched tested by an accredited company then :p "

All New Planet Audio Amps come with birth sheets. Sorry I dont have one of those but I got one of these




Here is a link on the planet audio amplifier review by Car Audio magazine

http://www.caraudiomag.com/testreports/0108cae_planet_audio_pa2500d_car_audio_am plifier/index.html


"I no exactly who Zed Audio are..and just like almost ever other company they have there lower lines, and Planet audio is just that a lower P.O.S. brand just because Ford makes the FordGT doesnt mean they dont make the Ford Focus as well..."

Quality is Quality Anything made in the USA is better than something made in China. Its like comparing snap on tools and china made tools.We are also talking amplifiers not cars or tools though

"Yeah but at what cost? Some sony amp are CEA compliant to do 1200rms...but at what cost?? High Harmonic distortion?? High Intermodulation distortion??..."

Sony Amplifiers are not made here in the USA So they dont go by the same rating system

And will Someone , anyone please click on the links on the planet audio amplifiers I posted above and confirm the 1200 @ 4 ohms briged mono on the first one and 1250x1 @ 1 ohm watt rating. Cause hes having a hard time reading the auctions evidently

Anyway Chauncey maybe you should come down here and spend a little time in my Shop
