Getting back into car audio a little bit and was curious about something. Currently I am using in my setup a Rockford 360.3 processor and a Prime R400-4D amp active setup on my front stage 2-way components. Sounds really good, I can not complain. Prior to that I was running a Punch P500-2 on my front stage using passive crossovers and the 360.3 processor.



I started looking around at other amp options now that I am confident in the active setup. I started looking at brands like McIntosh, Zapco, Arc Audio, Nakamichi, also the RF Power series, etc that are well known for SQ products. Both newer and older. Then I started looking at the older RF A series like the 600a4 and the 800a4 that were made in the USA.

THE MAIN QUESTION

Anyone that work on amps or maybe have more knowledge about amps then most able to chime in on amp quality today vs say the late 90's early 2000's when it comes to sound quality and build components?

My biggest hang up maybe nostalgia vs facts. Thinking that the RF 600a4 is just a better build then say going with the newer T600-4. When my guts is saying newer technology, cost in materials being lower, the newer products should be better.

RF is the main brand I am considering on amps but same comparison with any manufacture Alpine, Kenwood, MTX, Pioneer, Arc Audio, PPI, PG, Zapco etc that maybe is your brand of choice.

I want to go with the best SQ I can but not buy into marketing or nostalgia

Tradeoff? new tech, cheaper components. great components, old tech. although im sure the higher end companies use new tech and good components, but you def pay the price

Sound quality, its all subjective. Ive played with multiple amps, cheap, expensive, old, new and they all had their personalities. and I used pq20 a while back, and Im now back to the pq20(.2) again.

these amps are ~15-20 and they still work well without problems. Its just having to find that one that's not gona give you problems due to its long history and multiple owners.

Just remember, its a FACT that older amps fail, and when they do it will cost you more than then cost of a new amp. The new amps from reputable brands that care about build quality will last you much longer than that older amp you are looking at.
IF you are looking at a rebuilt older amp find out who rebuilt it, talk to them to see what was done and if its worth paying that price.

We really can't say newer will last longer than older because there are great examples of both!

Amps fail from abuse mostly. With power as cheap as it is now more amps are getting abused. Take care of your stuff and it will last a very long time. That's why I prefer to always buy new, no telling what the previous owner did to something

True but I have been reading about how old caps breakdown even if they aren't leaking. Now I am thinking I should recap all my Orion amps I am about to use just because they are older.

So couldn't older stuff just fail from age due to components breaking down over time regardless of abuse?

Other than the use of Surface Mount Technology, modern class a/b amps are essentially the same as they were 20 years ago. Not a lot of progress has been made in that topology.
On the other hand, class D amps have come a long way since they were first introduced. There really isn't anything "old school" to compare them to. New, higher quality class D amps have faster switching speeds resulting in a lower noise floor and better sound quality. Of course, they are also many times more efficient and run cooler.
Having said all of that, there is absolutely nothing wrong with running old school amps in either a daily or competition system. As long as you take care (maintenance) of them, don't abuse them and follow the manufacturers original guidelines, you will be fine.

All 100% correct PPI Guy!

OP - Truth is, you're probably not going to hear the difference between a common Class D design today and the nostalgic class A/B. I was an installer in the late 90's (was my dream job LOL - for about a half second). I personally have "Old School" (a moniker I think is completely ignorant) Eclipse, Fulton, Fultron Competiton and Crossfire amps from the late 90's that are fantastic amps in their own right and chose to go Class D for my new build. Small, efficient, quiet, powerful, inexpensive is hard argue with. With Class D I can fit 2 4 channel amps totaling 1000 watts RMS under my truck seat.

Of course, what you prefer is entirely up to you.

Cheers!

Welcome aboard another Kentuckian!
Can I ask what shop you worked for in the late 90's?
I was pretty much out of the hobby by then but, we may know some of the same people. You getting back into car audio or just checking out the scene?

The last new amp I used (on mids/ hi's) was a JBL GTO 75.4. It had plenty of power, the only issues I had with is were oxidized dip switches that would give me hell from time to time, scary when 280 RMS suddenly drops out on you while playing the system.

I am and have been using the PPI's in my signature for 5 years or so and still loving it.

Not at all.. it was Audio Center in Richmond KY. I think I worked there from 1996-1998. Seems like the right span.

Just getting back into it for my own vehicle mostly. I've also been helping the ford owners figure out the stupid-complex ford sync system. That's been fun too. I have a build log started for my Explorer if ya wanna take a look. I'm early in the process. Just put a 5.25" Eclipse center channel in to today (upgraded the stock 3.5") will post photos tomorrow.

I think I remember Audio Center in Richmond. Did you guys sell G&S Designs amps at one time?

What new class D amps did you decide to go with to replace your old school Fultron and Crossfire units?

JL Audio JX500/d for a JL 10w3v3
2 Soundstream Tarantuala 150x4's for everything else. (They are the same design as a bunch of other Class D's right now but around 100 bucks)

I think the OP is talking about the reliability of old amps because they are now 20/25 years old. Let's face it the electrolytic caps will be far past their best and looking at the MTBF (Clicky if you don't know what it means) they will be approaching the far end of the bathtub curve because the electronics will have been run for so many hours. So it would be foolish to think that an old amp is a fit-and-forget type of experience (says the person with a stack of old soundstreams squirrelled away for a rainy day :) )

Let's not forget the strong appeal of nostalgia in all of this. When I am at a show it's so easy to walk by vehicle after vehicle with the standard brand names installed. Usually all quality gear but, I will always stop at a car running old school gear. Maybe it's my age or just the novelty of running inefficient old Made in the USA class a/b gear. LOL!

I've been running four or five 25 to 30 year old amps in my car now since about 2010. I had one issue, but it wasn't the amp's fault and it was easily repaired. My bass amps have been in for over five years running low impedance, frequently warming up, etc with no problems. Knock on wood but I would further say I know several with similar results.

I don't recommend replacing caps just because they are old. It won't hurt (as long as it is done correctly) but I've never found it to be necessary.

I get the bathtub argument, but we're really discussing how big the bathtub is so to speak. I would say it looks like my old amps are easily in their useful life period.
