question

[ydnap]

I'm selling my car in about a week's time (well gonna start marketting it) and was wondering something.

How hard would it be (or expensive) to get a psu that would allow me to use the MPS indoors?

If it would be cheaper to get an amp (house amp) when I get home then I will leave it in the car, if not, Ill take it with me.

Bear in mind I can get a small NAD amp or the like in the UK for about 90 pounds, so it would need to be cheaper to get the MPS working indoors.

Cheers chaps.

Besides the necessity of acquiring a 12v power supply to use the amp in a home setup you have to consider how you're going to load the amp. Do you know what kind of power you're going to get with the typical 8 ohm loads of speakers designed for use in a house?

You only need a 40 amp power supply if your paying attention to the rated output of the amp. I have one but it weights like 48 pounds to ship, but its a Lambda linear type power supply so thats why its heavy

You could use a switch mode power supply to save weight and money I use a Lambda 90 amp switchmode < about 15 pounds tops> on my bench with a couple 1/2 farad caps just for good measure across the outputs but thats enough to run a much larger amp like a 2125 or the like at low ohms.

Like JED said the MPS will not play loud at home speaker loads so you would need to stack loads to get the MPS to humm along for you mate....C

It would likely be cheaper to get a home amp, when you consider the current your MPS amp consumes. The power supplies that car audio shops use in the sound demo boards cost upwards of $1200.00 at least thats what the ones at the last shop I worked at cost. I have a small 4-6 amp power supply for bench testing stuff and it was $80 8 years ago and it would never do what you want it to for more than 30 seconds max anyway.

I was going to keep the 6x9 point reference and box them
