small car amps
 
Does any company make small amps? Most amps available now are large, showy, and aimed at the image/shiny lights crowd. I'd like an amp that can EASILY be hidden anywhere in a car. So any options available to me? At the moment I have a Sony Mobile ES series 4ch. measuring about 7x2.5x10.5" without endcaps that works great but is tricky to put anywhere in my small car without taking up valuable space and kept hidden.

The problem is heat. Most car amps are class ab and highly inefficient, in the range of 20-30% most of the time. With that much heat being burned off in the amp, they need a reasonably large heat sink, and they also need to be mounted in a place with adequate ventillation. The smaller the chassis and the more "hidden" the amp is, the higher the risk of frying the amp.

Anyway, Linear Power used to make some small amps, you can still find them on ebay or the FS section of many car audio forums. Xtant had/has a small full range mono, but since it's mono you'd need several of them, which kind of defeats the purpose.

Yah, I understand that..it's just annoying that most 2 ch now seem to be bigger than my 4x35 sony.

If your are thinking of building one yourself, http://www.41hz.com/ have some class d amps fairly cheap..
And then you can make a custom case for your car that could fit in anyway you want
Im thinking of getting the amp2 myself for a bassamp for my band.

The new Alpine PDX range of amps are full range class D, in a TINY PACKAGE!! They are about half the size of an A4 piece of paper, and with plenty of power on tap!! (4x150wrms @ 4ohm)

As for sound quality, I have not heard one yet but word is they are good.

I just checked and they are about the same size as an A4 257x192x62 (10"x7.5"x2.5").

All people I have spoken to who have held them have said they are smaller then A4.

Either way, they are tiny amplifiers.

They are small for the amount of power they put out. But unless the Alpine website is wrong they still are close to the size of A4 paper.... :)

Dimensions
Width .................................................. ...............257mm (10-1/8)
Height .................................................. ............. 62mm (2-7/16)
Depth .................................................. ............. 192mm (7-9/16")

Not trying to start an argument, but just getting facts straight.

You could try one of the old Blaupunkt PA series. The plastic case can come off to reduce size. They use Tripaths Class-D (refuse to call it class-t) chips. I believe these are all the models in the series.....

PA275, PA2100, PA2150, PA2200 and PA4100.
