Hi everyone!
I want to put a Gainclone in my car to drive my woofers and tweeters and an Hypex module to drive the subwoofer. My problem is the power source. Could I connect the gainclone directly at the car battery?? Or I need to stabilize it??
Another option I thinked about is to unmount two SMPS from some car amps and use it for Gainclone and Hypex module.
What is the best solution??
I don't want to hear noises because of the feeding!!

SMPS is the solution. The minimal voltage for a gainclone is +/- 10 V but that is not a good supply range. Some designers have already make SMPS for gainclone. for yout Hypex module, SMPS devices could be more expensive : big fet, transformer (...) I hope to see soon the result. 😀
The switching of the power component in an SMPS creates "noise" that most here would insist is not conducive to creating a quiet audio system. As a result, SMPS's are generally avoided.
I've thinked for another solution: I could put an inverter dc-ac to get a 220v ac and then use toroids transformers to feed the gainclone and the hypex. What do you think of this solution?? Will the battery dead for the power consumption or it will stay alive?
SMPSs
Then why do ALL Car amps over 25W/Ch use them? Alpine, PPS, Phoenix Gold, Pioneer, Kenwood, Soundstream, etc. etc. etc.
Do a search on SMPS here on the forum, you will see that there is alot of dicsussion on the proper implementation of SMPS technology for both AC-DC offline and 12V DC-DC applications.
Albert, using an SMPS will solve alot of your problems in powering the GCs, but you may need to modify an existing SMPS to fit your exact application. Check out Rod Elliot's website- there are a few DC-DCSMPS projects for exactly what you're doing.
