Post subject:  planing a build with the M series amps

hi guys I'm planning a build with 3 M series amps and just wondered how good these amps are compared to newer amps on the current market..?

What would you put them up against..?

This will be my first old school amp build obviously I'm using new school speakers..

Thanks

its not an apples to apples comparison. Most modern amps are class d made for max power and ok/good enough sq. The m's are class A and made for sq over power out.

Thanks for the reply are they pure class A or A/B..

I know its not a direct comparison but just wondered in today's world if these amps were still good all these years later.. I will be going 3 way active.. I have all the gear and my car is in the shop now..

I suppose I'm just wondering if ill be disappointed with the amps..?

The rest of the gears really good..

well asking here isn't going to give you the most unbiased reply :) It depends on how you like your music. These are not made to vibrate the cars 2-3 cars away but they can be made to vibrate the car next to you with some sweet sq. I am planning on my next build being MS amps and have no fear.

I will be using 3 M series amps..

Post subject:  Re: planing a build with the M series amps

This is the system as follows..

So this is the layout for this setup with the old PG M series amps.
Source: Fiio X5 III + Pioneer something for Satnav and other stuff
DSP: ZAPCO Z8 IV II
Tweeter: Audible Physics RG50
Midrange: Audible Physics RG100
Woofer: Audible Physics AP6.25
Subwoofer: Hybrid Audio Clarus 12

Midrange on dash at OEM location in custom install in free-air. Tweeters close to the mids on A-pillars. Midbass in 14L net volume enclosures, possibly ported. Subwoofer in trunk in custom sealed enclosure, 35L estimated.
Trunk layout is still changing, but the amps will be in a straight line. It’s very tight, but looks classier. 2nd battery in spare wheel well. DSP & power distribution are not decided yet. Subwoofer in right side cavity.

It's a work in progress, the speakers sound real nice I know that much you can't get the RG100 4" wide bands anymore they were limited edition. I just hope the amps don't let the rest of the system down.. I will be using digital output from my media player to the zapco dsp..

The guy that's doing the install is an extremely good installer and is the European champion at EMMA in SQ.. He only charges £200 a day.. I'm booked in for around 19 days..

Post subject:  Re: planing a build with the M series amps

Instead of sharing pictures on this site I will give a link to my installers page so you can follow the build and see his other projects.. I probably should have done this before.. But i thought I'd whet peoples appetites with a few pictures on site first..!

If you guys want a build and you live in the UK then Peter's your man..

Enjoy..

Where did you find these amps in this condition?
Hope you changed the power supply caps...

I have been getting used to the system in the car now I had it a while.

It'ss due another tuning session now it has been run in.. I've seen n heard some good systems, but this things like next level top shelf.. I'm well happy with the outcome but it came at a price all in about £8,000, but I feel its money well spent..!

Post subject:  Re: planing a build with the M series amps

I bought the M-50 for a subwoofer up front but it ended up the midbass is that good in my car I don't really need a subwoofer in the glove box..

Post subject:  Re: planing a build with the M series amps

Your install is looking great.

I don't know if you sorted this out or not, but the M series are Class A/B.

To my knowledge no one has made a Class A amplifier for car audio use. I have seen amps marketed at Class A, but in practice they were high bias Class A/B, not a true Class A output stage. These amplifiers operate in a Class A range longer than a traditional Class A/B amplifier, but they really don't have the same fundamental design as a Class A amplifier.

Now, there might actually be a real Class A car audio amp out there, but I just never came across it.

Class A amplifiers are very inefficient, and very few car audio systems would have the power (current capability) to support them.

For example, I own a pair of Class A mono amplifiers for my home audio. They draw around 1000W each from the wall outlet when they are not playing any music at all. Back in college, they easily kept my dorm room warm, as we left them on 24/7, so they were always ready to sound their best if we used them.

thanks for the comment..

As it happens I have been thinking about a valve pre amp output stage..
