    I am looking for some high quality, high efficiency, 2 ohm 6 1/2 components for my GTO.

    They will be running off of a US Amps USA-4300x.

    Sound quality is most important with output being a very very close second (hence wanting 2 ohms and high efficiency).

    So, any suggestions for high quality (in sound and build), high output 6 1/2's?

    Price cut-off is < $500

    Power charts mean nothing. IT's the entire package you have to look at. Hello. . . If that is the basis of your argument, then why arent' Semi trucks killing everything out there? They have far more horsepower and torque than anything on the road.

    As for your "Ford was busted for overating the Mustang" comment, check your information on exactly WHY they changed the rating on it. Horsepower is not everything anyways. The 302 Mustangs had 300ft.lbs of torque which really helped to propel them out of the hole quicker with there LIGHTER WEIGHT.

    I have been following the 5.0L craze since it began. The Camaro was not a factor until the 4th gen F-body.

    If the Camaro WAS so much better, what happened to it? Why did it go away? Why did it not sell? Why did it NOT spawn an entire new generation of hotrodding?

    It doesn't matter much of anything, you simply cannot deny the Mustang what it's due. Everyone hates the Yankees because they are successful. Everyone hates JL because they are successful. You want to pick on the Mustang because it has been a constant staple in the US, and icon. It has achieved a legendary status that not many other cars have. It is noted throughout the world. It started a new generation of car making. It spawned an entirely new aftermarket, it's own national race series and to this day continues to outsell it's competition, no matter what.

    The Camaro is and was always a great car. But that is as far as it goes. IT will never achieve the status the Mustang has.

    OMG... You must own one and have caught the "Mustang Disease".

    The argument is which is faster, not which sold "better", but wich is faster.

    The Camaro has been faster it's entire life but maybe a FEW select years (yes I know I already said this, but I obviously must say it again). 300ft/lbs of torque huh? Yea... that's much better than the Camaro's 345. Yup, sure is.

    And I already know WHY they changed it. I read up on it WHEN IT HAPPENED. They were forced to.. plain and simple. sure, I've read the "pro ford" websites that say "they were trying to be more honest". Bullchit... they were forced to. And, hypothetically, if it WERE true... then why the hell weren't they honest before? Catch 22 I tell ya!

    That is completely incorrect. The 3rd gen F-bodies could NOT hang with the 5.0L fox bodies. That's been proven over and over again. Matter of fact, at that time, the only GM product that could hang with them were the GNs. Hence the Mustang/Grand National wars of the 90s. The 3rd Gen Camaro was back then what the Mustang has become recently. Underpowered and overweight. The fox-body Mustangs were light and had more than enough power in stock form to hand the Camaro it's ass. AND it was cheaper, and spawned a HUGE aftermarket following. It wasn't until GMs 4th gen F-body that they gained the performance advantage. Lighter weight and more power, not to mention a great suspension. The aging fox-body just couldn't compete.

    Mustangs couldn't compete with anything in the 70s. That's the Mustang IIs generation and was a huge flop. With all the smog wars going on, that was a decade that was lost in the power arena and pretty much continued into the mid to late 80s.

    As for the Supercharger debate, there really isn't one. If Ford really wanted to design a NA engine to put out enough power to hang with the LS series engines they easily could. Any manufacturer could for that matter. However, it's more cost-efficient to simply add some boost. They have done it quite effectively and cheaply while adding massive power and reliablilty all the while maintaining efficiency, and that reliability and efficiency is the key. Chevy does what works for them best, Ford does the same.

    Your comparisons are really off here too. What is the point in comparing a Ford GT to a GTO with a blower? There is none. Yeah, a GTO with a Blower and SERIOUS mods and money MAY be able to hang with the GT in straightline performance, but that's it. It won't get anywhere near the car in a corner, it will never look as cool, it will never have any value. That's like comparing a Vette to a Ferrari. The Z06 has European Exotic performance in a considerably cheaper package, but it's still just a Vette. It won't get the attention a Ferrari will, it will never have the status, it's still made with cheap plastic parts, it still has the creaks and squeaks that Chevy is known for, etc. . .

    You can get Bentley-LIKE luxury in a Lincoln or Cadillac for a fraction of the price as well, but it's still not a Bentley. The apples to oranges comparions just don't work.

    Where are you getting your information from?????? The Fox body was slow as hell. The Iroc-Z of the 80's, and the Z28 of the early 90's had 10-40 more horspower (depending on year) Hell, the Rustang came with 302 cubes, headers, true duals, and STILL only made 205hp. The chevy 305, with manifolds, and single exhaust made 230. Jump up to the 350 for 245.

    Here's some charts I found on the net to compare all 3rd gen years of both cars. Obviously Mustang III Started in 79 while Camaro III was in 82, but you'll see the differences (camaro with more every single solitary year) from 82-92... the entire 3rd Gen Camaro run. Also note, that in 1992, Ford was busted for "overrating the 302", hence the reason the 1993 302 is rated 20hp less than the previous years (it was the same damn motor). So, all those "225's" you see on the Ford chart can safely be dissmissed as "205's".

    i dunno. i like the challanger and the new camaro. will they have the staying power of the mustang? probably not. but like always, they'll whip it on the track, lol. also, from what i understand, the camaro will be priced close to the mustang. time for a bit of googling.....

    wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee :slayer:

    Like always? I'll have to strongly disagree here. In the Muscle days, it was really a tossup. I don't think anyone really won that war. There were so many available options, you could literally order a car anyway you wanted it. Early 80s to mid 90s, the Mustang was THE pinnacle of performance. It spawned an entirely new genre in the aftermarket industry. It's aftermarket is rivaled by NO other. It wasn't until Ford switched to the SN-95 platform and kept the 215HP 302 in an overweight aging chassis. Hell, it didn't get a redesign until 05. You can literally take parts from any Fox chassis from 77-04 and they will all bolt right in. The new F-body finally had the performance package with a larger engine, more HP and torque, less weight, and better handling in 93. But they did not sell. I don't know why. They were slightly more than the Mustang, but had a huge performance advantage over them.

    Call it whatever you want, but the Mustang has always set the bar, and has continued on and will continue to as an American Icon. It is THE original pony car and all others will simply follow in it's hoofsteps.

    Sorry dude... The Camaro has whooped the Mustangs ass consitantly the entire time it was in production save a select FEW years in the 70's. The 3rd gen RS Camaro with the 305 could run neck and neck with the GT... the Z28 creamed it.

    Also, the engines going in the new Camaro are far more potent than anything Ford has... and that is WITHOUT a SC. Poor Ford can't build an engine to save their lives (or company really, lol). They need a SC just to stay close enough to the N/A Vette just to SEE the tail lights. Even the heavy ass pig the GTO is stomps the crap out of the Rustang GT... With a few minor mods, it'll cream the SC'd GT500. With a SC, it'll cream the Ford GT (and any fool that will pay $150k+ for a FORD has serious issues. The Z06 WITHOUT a SC, and HALF the price destroys it on the track). Hell, with bolt-ons and ethanol, a member of ls1gto.com dynoed 766hp to the tires!

    The Challenger won't fail because they are smart enough to offer different trims and power trains... as long as they price the lower models low enough. However, the SRT-8 will be a rare bread. If it weighs what the Charger weighs, it'll be no faster than a GTO, at 15k more. That is over priced.

    The Camaro won't fail for the same reasons. However, the top line Camaro will be a GT500 killer, and will run just a tick behind the Z06.

    Impossible, period. Even if it were, it would shatter all the windows in the car instantly. A sonic boom 2 miles up is loud enough to literally shake an entire building on the ground (I hear them daily at work - right by an AF base).

    A sonic boom can only be created by an object breaking the sound barrier. The piston would have to move, in ONE direction, in excess of Mach 1. Same goes for the port velocity. That is created by the backwards motion of the piston, so it is dependent on the speed of the piston. It doesn't matter how fast you can make it move back and forth, as it must exceed Mach 1 in ONE direction (i.e. Mach 2 if you count forward and backward directions) to be successful. Now, think about what it take for a jet to exceed Mach 1. Most jets capable have upwards of 20,000 pounds of thrust, or more, in order to achieve those speeds. Also note that this is at high altitude where the air is much much thinner with much less resistance. Try converting that to watts. It is not eay to do because of the way thrust is derived, but a good way to "get a good idea" is here:

    Luckily, we do have access to data from a NASA report that does provide all the data we need to illustrate a sample case. The data is provided for a Boeing 747-200 cruising at Mach 0.9 at 40,000 ft (12,190 m). In this example, the aircraft's engines produce 55,145 lb (245,295 N) of thrust, only a quarter of its rated static thrust, to cruise at a velocity of 871 ft/s (265 m/s). Using the equations provided above, we calculate the power generated by the 747 to be 87,325 hp (65,100 kW).

    The NASA data also includes a few other planes, so let's compare the power generated by the subsonic 747 airliner to a supersonic fighter like the F-4 Phantom II. In this example, the F-4 cruises at Mach 1.8 at 55,000 ft (16,765 m). The aircraft's two turbojet engines produce 11,560 lb (51,430 N) of thrust at its cruise speed of 1,742 ft/s (531 m/s). This combination of force and speed equates to a power of 36,620 hp (27,310 kW).

    Source: http://www.aerospaceweb.org/question/propulsion/q0195.shtml

    Now, look at those numbers. 27,210KW... Not 27,310 watts... but KILOWATTS... That's 27,210,000 watts. You have a sub that can handle 27 million watts? Hell.. even an amp that can output that kind of power?? It is physically impossible to achieve. You would need ONE sub that could break the sound barrier. A combination of 27 thousands subs on 1kw each would still not create a sonic boom as none of them would be breaking the sound barrier. would they be loud? Hell yes. Probably even louder than a sonic boom. But a sonic boom would not be created.

    Edit: Also, without some space age subwoofer material, "if" (huge if because it can't be done) it were successful, the pressure of a sonic boom would tear the sub to shreds.

    USA-4300x

    I've had this amp for several years now, and it is hands down the bext multi-channel amp I have ever owned (and I've owned a lot - should I show my age by mentioning the Carver M-4820 I had many moons ago? lol). The sound quality is excellent as is the build quality. I don't have much to say other than that, as that is what matters, right? But I can give this one testament to the build quailty.

    When we built the box for my 12"s in my old car (running off my old SoundStream Class A 10.0), about 3 years ago, we hooked everything up for a quick test. While it was playing I noticed smoke coming out of the 4300x.... yes... actual SMOKE coming out of my precious amp. So, I ran to the front and shut down the system to inspect the problem. One strand of speaker wire was touching the opposite terminal, running that channel on a dead short. Well, I fixed that problem, and fired the system back up. 3 years later it continues to provide awesome sound out of all 4 channels.

    How do these newer companies that you speak of compare to what SoundStream, Orion, Linear Power, and US Amps used to be, particular broken down in the following categories:

    Sound quality

    Build quality

    Overall "bullet proofnes" (if you were around in the 80's and 90's you know what I am talking about in relation to the companies above - I've seen both a US Amps and a SoundStream used as a cutting torch all day, and still pound away when hooked back up)

    Are they "underrated"? (Again... see above...)

    All in all.. how do they compare? I currently own a SoundStream Reference Class A 10.0 (arguably the best car amplifer ever produced) and a US Amps USA-4300x (have "accidently" had this on a dead short with no damage - still sounds awesome). Both have served me well over the years (the SS has been running on a 1/2 Ohm load since 1995 and still pounds away), but in the new car I want matching amps for "looks", but want to retain the quality I have now.

    Hey everyone. I found this site while looking up stuff about US Amps, and I'm glad I did! So, I'll be lurking here and there.

    Name is Mike, and live in the Warner Robins, GA area. I am an Electronics Technician in the Navy, and Systems Administrator in my civilian life. I've been heavily into home and car audio since about 1987, and have a deep appreciation and love for the old school, hand crafted in the U.S.A., quality gear that seems to be rapidly going the way of the dinosaur.

    Hope to get to know some of you, learn from some of you, and maybe even share a little knowledge with some of you.
