Did my amp overheat because of a lack of ventilation or am I asking too much of it to drive my system?

Here's what happened and my set up.


I was watching a blu ray movie today, at a decent volume, about two thirds of the way through my amp switched off and the standby light was flashing. The top of the amp was very hot to the touch so I assume it's overheated and tripped out.

The amp isn't enclosed at all except for a glass shelf about 40mm above it. TV unit is an Off The Wall Origin S3 and the amp sits on bottom of the unit.

I have a Denon X2300 AV receiver. Probably a couple of years old and it's never tripped out before.

It's running a 5.1.2 speaker set up comprising of Q Acoustics 2050i fronts, 3090 centre and two pairs of 7000 as rears and heights. With a BK Gemini II subwoofer.

Crossovers are set to 60hz front, 90Hz centre, 110Hz rears and 200Hz height

Speakers are rated as follows.

Floorstanding fronts: Frequency Response (+/- 3 dB), Recommended Power: 25-150w, 6ohm Nominal Impedance, 4ohm Minimum Impedance, 92dB Sensitivity

Centre speaker: Frequency Response (+/- 3 dB): 75Hz - 22kHz, Nominal Impedance: 6ohm, Sensitivity: 89dB, Recommended Power: 25 - 100w

Rear and height: Frequency Response (+/- 3 dB): 95Hz-20kHz , Nominal Impedance: 6ohm, Sensitivity: 85dB, Recommended Power: 25 - 100w
 
Thanks for the reply. I'm using banana plugs so it's not a short. Speaker wire is 2 x 1.5mm Multi-Strand 260 (2x 130 Strand) Outer Dimensions: 6.5mm x 3.1mm. Don't know if that's good or bad. It wasn't expensive.

I'm not sure if this is the setting you're referring to but

I have the rears at -3db each and the heights at +7db each. The other speakers are at 0db.

Any suggestions on an amp with enough power to drive my speakers?
 
Thanks Lucid for taking the time to write a detailed and informative post.

Yes you're correct the cable came from Amazon.

I certainly like the idea of spending £50 rather than £900.

Can I be cheeky and ask for cable recommendation?
 
I bought 2 X 2.5mm 99.99% OFC cable.

Amp hasn't tripped out so far.

Not sure if it's a placebo effect but sound seems to be a touch louder at the same volume than before.
