97f250, Which Linear Power amps do you have? Would you like to sell them? They are real quality, along with the old-school Soundstream amps.

I have a pair of 992IQs that have been modified by Mr. Rayfield@Tips, Inc. to produce approximately double their stock power into 4 ohms. With the mods, they actually produce more power into 4 ohms than into 2. One is running my tweeters and the other my mids on a biampable set of a/d/s components. I have a 1502IQ running a pair of 6 1/2" Audax midbass. I got it directly from Mr. Rayfield in a trade. All three are in excellent condition, but not mint. They have some scratches on the fins. All three are purple. I've had ten or twelve LP amps over the last few years. I have an old school Hifonics running my subs currently. I just had it repaired by Mr. Rayfield as well. I had these three LP amps on ebay as a set about a month ago, but I cancelled the auction early because I had some errors in the description concerning the mods. If you are serious about these amps, I will list them in the classifieds here so I don't violate any forum rules. But they won't be cheap. The mods alone on the 992IQs cost me $270. And, I have documentation of the mods, cost, bench test, etc. Otherwise, I'm considering putting them on ebay again.

Many people many thoughts.... I like the amps that are rated at 12.6 Volts.

Most people don't even look at this (ex.) Lets say you had a alpine amp rated at 300 watts rms @ 14.4 volts next to a audiobahn amp at 300 watts rms @12.6 volts. If they were honest in their test, the audiobahn would give you more power. Also allot of people do not know that 79% of all amps are made in the same plant. We are about to debut our line of audio parts and have talked with many manuf.'s around the world. We know what's going on. We have built amps that had more power, more efficent and allot cleaner than JL Audio,PPI, Kicker, etc. Trust me you are paying more for the name than for the performance. We have developed a class d 1200 watt amp that generates 1374.6 watts, very clean and efficent and will be sold in stores for $299.99. It will come with a bass ****, an 18db boost, low pass 24 octave x-over, subsonic filter, and will be able to combine 2 amps to make 1. Watch for us, you'll know us when you see us!

Very valid points here. In the above example, the alpine amp could also say to me it's a hell of a lot less efficient than the audiobahn.

But also, the typical consumer won't know that watts out versus a given input voltage can be completely meaningless depending how the amp's DC-DC converter is designed, especially if its output supply to the amp section is regulated and fixed. So the audiobahn may not be able to pump out any more power, and the alpine could indeed outperform it simply because it might have a better and higher current power supply.

Probably a better subjective indication in the interim is how many watts the amp will pump out at 4ohms and 2ohms loads. Consider an amp that's spec'd to crank out a 400W at 4ohms but won't disclose it drops to <200W at 2ohms. Compare it with another amp that pumps out 400W@4ohms but will handle 400W@2ohms... The latter will almost certainly cost more $$ than the former. Which one is better?


So what or whom to believe? Rely on 3rd party testing against a common specification/test criteria.

Regarding manufacturing at the same plant...very true statement here too as everyone these days is trying to increase margins by going to offshore contract manufacturers (CM's). But just because the product was assembled at the same assembly plant doesn't mean they're all good or inferior. The same CM can be building highend workstation motherboards one day and then lowend consumer TV's using inferior components specified by their customer the next day on the same assembly line. Build/design quality isn't necessarily decided by the CM. It's instead driven and specified by the original amp designer.

Unfortunately, most people won't know the difference by simply looking at the box without opening it up and blindly buy based on how good the heatsink looks and marketing specs alone...most manufacturers know that. Then there's the group of folks who buy based purely on price... you get what you pay for.

Also very good points!! Talking with allot of manuf.'s they did offer us allot of diffenrent designs, some of which combined some of the same designs found in some great name brands. But we decided to build our amps here within the US We could save the consumer about $50 going oversees but we decided to keep people in America working. The same thing went on with our subs. I have noticed that since allot of compaines are joining in and complying with what I like to call the "truth act", we are still noticing some false output power. One major company advertised a 2400 watt amp outside the box. Inside the box was their little truth on power. It was a 847 RMS watt amp @ 2 ohms. Of course the amp was only 2 ohm stable (mono). Some might ask how they got 2400 watts? I know for a fact that some compaines wire their amps to 1/4 ohm or less, pump it with 18 Volts and get the peak power right before it blows up. If you see an amp that has a power rating that seems to good to be true for the price, pass on it. It is better to save your money. We have people come in and by 4 amps over 3 months wanting more power, we tried to tell them, but on the 4th trip they purchase a great amp with lots of power. Then it breaks their heart when we tell them, "If you would have combined all the prices yoou paid for the other 3, you could have got a much larger amp."

Well we have 3 names we have got it down to and we have to make a choice soon. We are hope to have everything ready to go by the Next SEMA show, but we are open to suggestions. Any takers? Here are the 3:

JB Acoustics

Collision

DB Effects

IMHO, the first one sounds most credible.

The others sound like toys. I'm probably in a minority group,
but I'd probably won't even look at the amp based on a
gimmicky-sounding brand name!


ahhh... the wonders of what some simple Marketing can do
to consumer thinking...
