I have the motor out of my car and of course did not tag any wires, just figured I plug in wherever they reach! :D I have just bought a new Pyle cd player, would like put in and try but what do I need to hook up to the battery to get power there? Can I just go straight from battery to stereo or do I need to get power to the fuse block? Will the stereo run off of 12V or is there some type of transformer that bucks that voltage? Please I really want to hear my new speakers graemlins/beers.gif

For a test, you can run directly to the battery. Use a fused wire with fuse close to the battery. DO NOT HOOK UP BATTERY CABLES ... Just run ground, power and memory wires directly to the battery. Even if you are running an AMP, this will work, but eventually begin to drain on your battery .

thanks that what I thought graemlins/thumbsup.gif

Are talking high power here? It is always beneficial to connect stereo equipment directly to the battery especially if you are running power amps. But a word of advice. Fuse both the hot and the ground leads. Run hot and ground to your amp rack. The reason for the fused ground is so that your starter or some other high current device (or short) doesn't see your amplifier's guts as a circuit path. Direct from the battery power will have less alternator whine, ignition noise, and present very little voltage sag if you're pulling watts. I have two rubber all-weather jumbo ATO fuse holders with 30 amp fuses in them for my power feed. I then fuse it down to the appropriate size for each load.

Cool idea! Are you saying I should bring two seperate wires from my battery, thru 30 amp fuses, then thru proper fuse size, right to my stereo leads? ( power memory and ground)

Would I need a temination block somewhere? I have a 200w Pyle, with 250w rear speakers now. I plan on two more 4" speakers up front, posssible subwoofer and an Amp in future.

Yes, two wires, hot and ground. For those who may be wondering, this does create a ground loop. But current takes the path of least resistance. For the engine, that is through the short cable between the block and the battery. But the wire you run to the amps, if properly sized, will present less resistance than the frame and body. As a result, you get less voltage sag and you have a clean connection to the battery with no other loads connected to it. But fusing the ground is important odd as it seems. Foil traces within your head unit, cd-plater, amps will vaporize if a ground fault occurrs during a start or a battery jump if the negative feed isn't fused.

Darn the luck graemlins/angry.gif
