Custom PG amps

you just ground the amp to the neg of the battery, i do this all the time when playing/testing stuff.

i have a battery pack/jumper i use for testing smaller amps and if i need more oomph i use a spare car battery.

i use an old alpine headunit that's ran off it's own little 12v supply and just plug rca's in and away we go!

Oh cool, easy enough then. A battery pack from an RC model shop might work I guess, for a quick test anyway. I can use an RCA lead from my preamp as an input to my PG's, then run my Dynaudios (which are 4ohm anyway). I'll go battery hunting soon

the battery pack i use is 12v jump start battery pack, not sure if rc ones will work, i can only advice on what i do on a regular basis..

not sure if I would recomend a small battery, smaller then a motorcycle really. All you need to do is to connect the + and - on the amp and the battery.

After some thought I have decided I may try and simplify this a little, closer to what I had originally imagined, so bear with me. I think I will most likely stick to a 2 way system up front with rear sub/s. So this eliminates some of the extra amps. This will obviously keep it more compact and a touch less heavy. I'll just keep the spare amps in my stash. So I'll be drawing up some different layouts for this soon...

MS275 - tweeters
MS275 - mid-bass
MS2250 - sub/s

Dude,

If you want to loan my power supply , you are most welcome, it's a 14A unit and will power most things up , I had it on the Da-Vinci while testing and it works really well.

That's kind of you, but the return postage would likely be epic to the UK!

I've never looked into power supplies, but it's a pretty good idea. I wonder what they go for?

mmmm, I am based in the UK... London North to be exact.

Still not done, but hopefully I will wrap it up soon!

Later,
Jason

You care to pm me the dimensions on that handbuilt unit
