i asked some1 who knows there sh it, he said infinity is what most people use because it has an rms of 111watts to each speaker. thats plenty plus getting it new on ebay for 200 isnt bad at all, thats half of what i want to spend... also how does infinity have poor specs show me some proof on that because every site i go to has great ratings on this amp.
That amp is junk, does not produce 111 watts of power, and has a dustortion rating that will definately make a dufference in your system. It will function well only i you keep it from about 1/2 to 2/3 power, as the distortion will be much lower. You may not hear it, but your speakers will. Over-power does not kill speakers, distortion does. This actually works fine for you since most speakers (co-ax) cannot take more than about 60 watts anyway. Seperates can take more, but still not much more than 100 watts for most speakers that the average Joe can afford. I run a store for the largest car audio shop in New Orleans and can personally tell you that the TDH can drastically effect the longevitiy of a speaker.For your money, I would recommend Eclipse EA4000, 4 channel amp, or the MRV-F340 from alpine. Both are top quality and fit within your budget. By the way, which radio (pioneer model) did you buy. Any thing under their DEH-P460MP is a waste of your money when it comes to adding amplifiers. Unfortunatel, infinity has become a lot like BOSE, they sell their products mostly by brand recognition and not by quality. Oh, they still make good equipment, but only on their high dollar lines. Several years ago, Infinity was terrific, but they have recently succumb to the ghetto rating MAX power system, which states you put the MAX power rating on the amp, with ton's of distortion, and you sell a bunch of overpriced product to people who don't know the difference.
A new rating standard has been adopted by major manufacturers of car audio to rate amplifiers equally. Thisis the CEA-2006 rating standard. Any amp worth a damn will have an emblem on it saying that it is CEA-2006 compliant. Also any amp with more than a .05% THD rating (for highs not bass) is junk. Lots of power doesn't make a good system, clean power makes a good system.
Being in the industry, I have the option of any brand or make amp I want at a considerable discount.. For my own vehicles, I use nothing except JL Audio.
I have noticed that Infinity has lost alot of that superb quality and performance they had a few years back. Im sure someone will disagree with me on this how about an MTX 3404? I have the birth certificate for our showroom piece and it reads 109x4@2ohm and .04% THD. And im sorry to say this dude but Professionally Installed and Circuit City never has or will be a factual statement. And F00 if you have access to any and every brand why would you be using JL Audio. They are no better than MTX, Memphis, Kicker, Orion or any other "High-end/Popular" Brands. Certainly you would be using stuff like RE, E. Designs, ARC, Hifonics, Cadence, ID? Unless you are Will Castro and have your own tv show and get paid by JL to make young uneducated kids think JL is the end all be all in car audio. Not that JL is a bad brand but they are far from the top.
sieght i would have to agree with you here that the mtx would be alot better choice. and for the reviews on CC they edit all of them i did a review on the amp and i went back and looked at it and they re rated it and changed my words so it looks like 17 people could be wrong. you can put 300 watts of clean power to a comp set rated at 150 watts if your no what your doing or your can blow 100 watt speakers with 17watts. and pretty much anything sold at CC or Best buy is sub par and for people who dont know very much if anything about car audio.

JL Audio's amplifiers rate in at .03% THD which for the money is an industry best. Their W7 series subwoofer is still considered as the premier sounds quality sub in car audio. ( if it was not the best, then every sub company in the world would not be trying to say "mine is better" for the last 2 years). Jl's ZR series components are probably the best balanced setup in the industry also. Boston Acoustics does have their Z line, however they need a large amount of power (125Watts per speaker) to perform properly (not to mention a huge crossover which make them a pain to install), and I don't have the room for the JL 450/4 amp in my trunk, so the ZR's were the obvious next best choice. As for Focal, and the others mentioned, I have never really been impressed by their product. Difficult to mount and balanced performance are key. JL's entry level line (TR series) actually sounds better than focal's top product. Don't take my word for it, they actually won best sound quality at the SEMA show 2 or 3 years ago, when they first came out, and that was against opponents as high as Alpine's F1 status line ($3k as set for seperated, and custom install is a must with a 2 1/2" tweeter). All things considered, JL actually does have the best product line on the market. And they did not pay me for that, in fact. JL does not sponser privately owned vehicles (only company show cars), so I had to pay for my setup. And other companies did offer me free equipment if I plugged their product.
JL has pretty good products but to say they have the best is a very bold statement. look at zapcos specs if you want to see an amp blow JL's out of the water. JL has some good subs but their is usually something just as good if not better. the new XXX from RE will kill the W7. DLS has amps that are better than JL and alot of them are Cheaper the JL 1000/1 is a 1000 bucks and the DLS A6 is a 1200 watt amp that puts out more power than that and is supper clean for 650 bucks. and DLS has been one of the Top SQ competitors world wide for years now and takes a top place in more than one catagory at every event.
Sinister and I with an agreement? Who would've thought? The XXX is definatly one better than the Dub7, The new Tumult without even hearing it yet I can definatly say it will be far better than the W7. Fantastic specs and Adire engineering as well, can't beat that. Hell the Brahma comes close to what a W7 is and their only $450. Zapco is one I left out, you can never say anything bad about Zapco. They are indefinatly some of the best amplifiers out there.

All outputs for DLS amplifiers are measured at <.1%THD, which isn't bad, but it does take it out of the same class as JL and Zapco. Zapco is great product, but it lacks the versitility of JL's Absolute Symmetry system. Zapco's flagship 4-channel, the 1000.4 is a great amplifier, even rates better than the 300/4 and 450/4, but it is way more power than I will ever need, or should ever need for a set of component speakers. I just didn't see the point is spending money for power i'm not going to use. That and the overall length of the amp make it an unreasonable choice for the allready compact trunk of Mustang Conv. I would have no place to put an amp that size. The 300/4 and 500/1 fit very nicely on the floor of the mustang trunk, and still leave room for caps and a box.
JL had the right fit, the right power, and the high quality that i needed.
DLS underrate their amps to be actually better than they say they are. they are in the same category as zapco and all the other top end companys. and JL has good stuff its just not the top of the line stuff. my bravox comps are alot better than JLs XR series comps and the JLs couldnt take the power from a 75watt DLS amp which actually produces about 125 because they under rate them and they are very reasonable in price actually much better than JL.

Thank you for saying this. I'm tired of hearing "The people at Best Buy said this sub was the best so I bought it."

Considering Best Buy doesn't sell this brand, that's pretty funny.
Another thing, i'm using the new ZR components,not the xr's and 125watts is more power than anyone should every need for highs in as small a space as a car.

What? Who said they did? His comment wasn't even about subs in the first place. My comment was in reference to everyone buying crappy equipment because Circuity Cuty/Best Buy said it was good. "Billy in the car audio department said XXXXXXX brand components sounded good so I'm ganan go with that."
It's almost pointless to suggest such brands to these people as they do not have the desire/know-how to employ such equipment. If you get a Zapco or Xtant or some ****, you need a good head unit, and good components, and sealed enclosures, and etc etc etc. I'm guessing about .1% of the people on here care that much. I think I spent abot 2200 dollars just to get my two front components working OUTSIDE of enclousures. This kid is talking about a $300 Infinity amp.

It doesn't matter what someone says sounds good, It is so important to go and listen to as many different brands of equipment as possible, I know that is not possible for some, I must have listened to 20 different sets of speakers, amps, headunits. It is what sounds good to you. I was lucky one of the places I went the owner was installing a system in a mustang and got to listen, and see what I liked and didn't. Obviously equipment does have something to do with it but your own ear is the most important.

That helps alot as well. It also helps to know what different sounds should acutally sound like it real life. (i.e. - take a trip to a music store or a recording stuido).

I'll admit it, the XXX is a louder sub than the W7, it better be considering that the 12w7 is rated for 750watts RMS, and anything more than 1200 voids your warranty. Meanwhile the RE XXX boasts 8500watts RMS. So while you out buying alternators and batteries for you car, I'll be pocketing the money toward speed parts. Also, JL as a company does not consider their product to be for SPL use. It is all designed for sound quality, without being something that a second mortgage must be taken out on to purchase. Your compairing a small block ford to an alcahol burning, blown, sprayed, Siameese bored drag motor. Now which one is realistic. As for the above picture, I'd love to see someone fit something like that into the trunk of a convertible Mustang.
My 10"W7 fits great into their with only 500 watts needed to get everything out of it. Prior to this woofer, I preferred the Eclipse titanium series for sound quality, but the cone area was too small. JL was the first company to solve the cone problem so that you didn't have a 12" sub with an 8" cone bcause of the size of the surround, and they have the patent on it. The only other sub which has been able to do this is the Alpine Type X series, with their surround that is ridged to expand.
I never said that JL had the loudest sub on the market. I said that it is the best sounding sub.And with small space and without a thirst for power, untill someone comes out with something more efficient that can still produce that level of quality, i'm sticking with it.
