Any advice as to where I stand greatly appreciated, these subwoofers were not cheap and I would expect them to last a considerable time. I oversee the fitting and all is in order, my first job upon leaving school was as a car radio engineer/fitter, so I do know whats what.

Given that you purchased the amp and speakers as a package you should expect them to work together correctly. Talk of clipping and so on is irrelevant, if the amp produces a signal that burns out the speakers then the product is not of satisfactory quality and the retailer need to sort it out.

djpleasure, you don't say how long it is since you bought them. If its under 6 months you'll have the best chance of success, and their warranty claim is utter rubbish (and in fact illegal, as they are trying to avoid your statutory rights). If over 6 months it may get more complicated.

Your next step ought to be to put things into writing. Send a formal letter to the Car Audio Centre (you need to deal with them, not Inphase) stating the sale of goods act and send it recorded delivery. Give them a set timescale to respond.

If it isn't resolved you need to look at letters before action and then small claims court.

you can quite happily use a 1kW amp to power 100W speakers its all about set up,was the amp fed a clean signal,where the gains on the amp set set according to the maximum clean signal being fed to the amp,if this was the case was the signal used for set up a singal tone or music.

who installed the equipment,its quite rare to get faulty speakers most of the time the fault is with the installation and set up.

thanks for that
ive just looked how hes wired it up and its a mono amp so why would he want dual voice coils ?

Dual 4Ω voice coils can be wired to either 2Ω or 8Ω.

Looking at the specs for a typical mono amp (Vibe Monobox IV)

500w RMS @ 4Ω

850w RMS @ 2Ω

1400w RMS @ 1Ω

So with a DVC sub you could go from having 500w from the amp, to 850w...

I just bought a Dual-2Ω voice coil sub for this exact eason.

Unfortunately then every "package" in the UK would fall foul of the same thing - if the amp isn't powerful enough, it will clip too early, if it's too powerful, it will melt the voice coils - there isn't really a way round it.
