Hey just a quick question . I recently purchased a car speaker amplifier and after doing research i still have one question. When you wire the speakers to the amplifier do you unplug the wire form the speakers to stereo or do you leave both of them connected. Thanks
Google it?? funny. Speakers can only have one power source per inputif the amp is powering the speakerthen the radio cannot. Perhaps the radio can provide a signal by way of the previous speaker connections.which is usually done with RCA connection insteadbut that is about all those connection are good for since you have the amp powering the speakers now!!! Unless this is a serious installationseveral thousands of dollars. the trick is to try and reuse as much of the factory speaker wiring as possiblewhereever the best points may be. I have software to tell me these points and each car is differentso maybe you should stick with the back of the stereo where you know all the speaker wires are instead of tearing apart several body panels.
There was a time when a thirty watt per ch at eight ohm amp would have been considered quite adequate. Stock, most cars came with less. Save at the very high end. If your speakers are standard oval Rear Deck speakers, it probably still is. It might otherwise depend on the magnet and coil size, and compliance of the speakers, and probably, they are 4 ohm drivers, so 30 watts rms at 8 ohms usually outputs 60 watts of control to 4 ohm speakers. If you have typical oval deck speakers with say, eight ounce magnets on them, getting a whopping big amplifier wont do you any good. It just means when you twitch the volume control a little to far, you will turn the cones inside out, and ruin them. If your car is an ultra quiet veritable concert hall on wheels, a really expensive rig might, might, be worthwhile depending on your musical tastes. If you are just drowning out engine knock, keeping up with the sports, FM radio, I wouldn't bother.
