Anyone know any good models that might fit the bill? My Fozzy's had it.

I wouldn't put an amp under the seat, not enough air cooling and they tend to fry.

If you do get a comp fan under there to circulate air around the amp.

Nice amp if it's got a fan it will help greatly.

I have this Sony Monoblock, doesnÂ´t create that much heat at all. So thats my tip to you.

I'm looking at an Alpine M350... should do the trick.
Glad to hear the CD's getting put though a good system!

If you are running bass and have to stick the amp under the seat then a class-d monoblock will outlive the Fozzy (they run Class AB or class A analogue circuitry - which make a very high-definition sound and very carefully controlled high-freq noise on the outputs but produce a lot of heat)

Class-D on the other hand convert the input to digital, use the digital signal to drive some very large MosFET transistors to create a pulse-width modulated output and then low-pass filter the end result to make an analogue output for the speakers.
The result is the amp will produce a lot less heat for the power. The downside is they produce high-frequency noise (Prof. Nyquist will tell you /all/ about it - but you don't want him too) on the output stage. This isn't a problem for running a sub - as the high-freq noise is too far up the spectrum to stand a hope of being reproduced by the cone.

My Kenwood 1000W amp runs on 30Amps peak and is only warm after hours of working hard.

by which time you've gone deaf and cant hear anything, let alone high freq noise!

I've gone for a class D, Alpine M350... It's running the sub now and did not head up noticeable on the 15minute run I just gave it

Cheers!

Good news mate - a very sweet amp!

@Murf - my ears bleed mate - I have got to start looking after them.
