Just a quick question, in the Alfa 145, where can I feed the power cable from the interior of the car to the underside of the bonnet? If nowhere, do I have to drill a hole and whereabouts should I drill. If anyone has any links to websites that can help that would be greatly appreciated. Thanks

The wiring to an amp i normally large for a reason (unless its a particularly pants amp), it can draw a lot of current and thats why it goes straight to the battery via a fuse of its own, much in the same way the starter does.

I would not want to be anywhere near your dash if the amp pulls its max current through the cars standard wiring, a honest bit of advice would be move it or at least beware for the smell of melting plastic, if you smell it turn the stereo off straight away if i where you.

1+ on what Hybrid said!

I really would recommend binning that off and buying a proper sub wiring kit with the correct sized B+ cable and the very important fuse! Although, your sub may work correctly, if you give it some hammer it will draw too much current for the wire to handle. The wire will get very very hot, the pvc insulation may melt and/or catch fire and/or short out along with other cables, foam insulation and bits of plastic and before you know it, you have turned your car into a barbecue! no3.gif

The feed you have tapped into may also be the services for the cabin such as radio, cig lighter, clock etc... At best this will be a 15 amp feed but once everything else is powered this will be considerably less. Given that most of the tiny little under-seat subs can draw up to 10 amps and for example, my cheapo 12" 100w powered sub can use up to 30 amps... You see where I'm going with this? Also, you may have tapped into a non-fused feed so if your B+ wire to your sub snags along any earthed metal and shorts, well we're back to the barbecue again!

Amplifier wiring kit

Keep left unless overtaking - Use mirrors and signals when changing lanes - Keep within the white lines - Don't tailgate

Its not exactly f**king rocket science is it?


If you cut a horse in half, then bang the two halves together, you get exactly the same noise as someone riding a coconut!

but my point (and fins) is that IF it does break it wont be fixable unsure.gif

But at the end of the day its your car and your choice, as long as my conscience is clear that i have let someone no the danger involved i can sleep easy when i see the 'BBQ 145' thread.
