Default Fitting a Sub

OOPS, Should have been the NW240SP 2 channel amp :-(

The HU power feed to the amp was the one I meant, to put a on/off switch.

would I be able to power both amps from the HU on/off wire?

Cheers

Have seen this http://www.mutant.uk.com/nw480sp.html, would it be ok to
power the sub?


No, it doesnt appear to be bridgeable to me. Though I might be wrong.

Why do you want a 4 channel amp? Are you planning to use the spare two
channels to power your front speakers or???

A bridgeable 2 channel-er or a D class single channel or, even simpler an
active sub (i.e. amp built in) is what you want.


Would I be able to wire the switched power to an ignition live and put a
suitable switch on it, so I can turn the sub off when my young lad is sat

in
the back of the car. and keep my existing amp wired up as it is, to the
HU
switched power?


No. Definately not. Do not switch the power feed to the amp. There is a
simpler solution. ( A reasonably powered amp (say 200w RMS) will pull
25-30amps under full load. You'll end up setting fire to something. )

The Amp is switched by a remote lead which runs from the HU to it. This
comes to +12v as soon as your power up the HU and carries only afew mA.
Put
a switch in this if you want to disable the sub.

EQ - equalisation - tone controls.
