When I turn the amp up loud enough to annoy the neighbours it cuts in and out, in time with the bass. It's as if the speakers are drawing too much current, they have been ok for 5 or so years though, it's only just started happening. Could a capacitor have gone or something?

this kind of problems usually happen when the amp is not getting enough current to power up the amp. the moment a loud low frequency hits the amp it fails. cud be ur power unit not giving enough power to the amp or u have a loose connection somewhere on ur power line. besides 8gauge is a bit small. try using about 4gauge. should have good ground too. they draw large current so ur battery should be in top condition as well.
If amp has pre out power in connections the try driving another amp from pre out stage. Try driving power in stage from another source. Swap round inputs to check preamp section Always start at low volume, check sound is ok at low the make it loud.

Use a multi meter,set it to 12v,turn system on use some bass.while music is playiing hold pos of multi meter to poss- neg to neg- on amp see what voltage is running at at what its dropping to it sounds more like a voltage drop problem.if you hooked it up back words u could fry unit..Have you done the big 3.what size is your alt,and what is your amps draw..
The problem is in amplifier section caused by change value resistor or leak capacitor or cold ,loose or crack solder joint parts this the common problem of over heating and shuts out the amplifier caused by abnormal distribution of current,try to check all the capacitor and resistor and replaced the defected parts ,so your receivers works normal again.
Normally this denotes a protect condition. Remove the speaker wires from the back of the amp and see if the green light stays on. If this fixes the problem, then there is a short circuit in your wires, speaker level volume control or speakers. The amp sees the short and goes into protect. After a couple seconds it closes the connection again and if the short is still present it goes back into protect.
Sounds like you like your music like me... LOUD. If you've done this a number of times, there are a few things that can happen:
1. You've blown the speakers... but you've said it operates for 2 seconds, then cuts out.
2. You've damaged the amplifier modules within the amp and they immediately overheat upon power-up. Does the music come back like 5 or 10 seconds after the unit cuts out?
3. Thermal switch has malfunctioned and just cuts off the power to the amplifier modules as soon as it sees any heat.
4. If you've gotten the amp really HOT during playing, it's possible that it's as simple as the amp modules are only intermittently connected (fatigued/stressed or cold solder joints) at the on the PCB. Just resolder the connections of the amp module to the PCB. I've seen that happen numerous times and that's where I'd place my money.
