You're getting some weird interaction between the new power supplies and the DC-DC convertor. I'm not even gonna speculate any more on what's actually... -
You might want to look at using a couple of the 2 channel Icepower boards. Reasonable price, great specs. Be careful looking at car audio stuff and...Leave a comment:

Just try something like this. You need plain and simple since you're already starting out with DC from the power brick. The input and output filter...Leave a comment:

The page at parts express shows 12V @ 1 amp. PG02S2412A shows a minimum draw of 42mA and a max of 167 mA. I don't think Sure would have specd the current...Leave a comment:

If I'm understanding this correctly the hum starts when you hook up the DC-DC convertor without the bluetooth board. It's possible that the hum is caused...Leave a comment:

Yup. Rule of thumb down a decade from the switching frequency of the supply and a simple 2nd order filter as a starting point. +- 20% is usually close...Leave a comment:

The only reason I knew how much they were is that I borrowed a pair from a friend who works for Molex. He laughed when I asked him about buying a pa...Leave a comment:

Why overly complicate things. Use a 7812 voltage regulator, good for an amp and half, and a small filter cap, 47uF, to feed the bluetooth module. 2...Leave a comment:

I don't think you're really going to find anything that's a "similar" design using modern drivers. The Kenwoods kl999dx were a 5 way with a...Leave a comment:

You could try playing with Hornresp. It lets you change the space that you're radiating in. Also, take a look at boxsim, it also lets you change the...Leave a comment:

That's an understatement. I've been playing with and measuring the midrange and high frequency horns that I got. Little changes in the crossovers make...Leave a comment:

Theoretically yes, but in reality maybe. It's all dependant on how the measurements were made and how they are reported. You're dealing with an electro-mechanical...Leave a comment:

12 or 14 gauge is overkill, rule of thumb is no more than 5% loss. Oxygen free copper zip cord, SJOOW even landscape wiring is fine.
Here's...Leave a comment:

I always take my measurements with a grain of salt. It doesn't take a lot to change a measurement, but it does give you a fairly reasonable comparison....Leave a comment:
