I was wondering...

Are there any amps in production that have:

Class A: Left & Right channels

Class D: Power stage for a subwoofer.

All in one package / Amp case?

If there isn`t.

Is there any reason why this couldn`t be done or hasn`t been done yet?

there are a few 5 channels that have an A/B for the mids and highs, then a D class for the rear,

for example the Kicker KX 700.5 and Memphis Belle are like that

Class A is expensive, inefficient, tough to cool. Hence you see so much A/B.

Class A is expensive, inefficient, tough to cool.

And totally kicks ass But for 12VDC, they're tough to implement. That's why 99.9% of all Class A amps you see are going to be used for home audio, where the inefficiency and size penalties don't matter.

ya i wanna hear one of those tube amps with my system. Heard it has unmatched SQ from any amp. Theyre hot. Literally.

Pure class A for car audio = teh sux0r

Nothing like running an amp that has a maximum efficiency of 25% off of the limited power supply available in a car You wouldn't, however, need to run your car's heater in the winter From what I'm told, the old Monolithic amp's heatsinks would literally glow at night (and they aren't tube amps).

Like Denim mentioned; there are a few 5-channels that have class A/B front end channels, then a Class D subwoofer amplifier. Then you have something like the Alpine amps, which IIRC have a psuedo-class D technology that they use on all channels.

Thanks Guys

Just had a funny idea about getting some amps made up.

Doesn`t seem like a good idea now.

Oh well.

Any ideas about the DEI 5channels ?( D2205)

I think they are a 4ch a/b and a mono D because they caxn take a 1ohm mono load
