It depends on the power and impedance rating of the 12-inch speakers. If both speakers are rated for 175 watts and the amp can handle the impedance of the speakers, then the 350 watt amp should be able to power both speakers effectively.
To power your speakers, and to ensure that your amp has enough power to power your subwoofers, you would need at least an amp of 750 watts true power.
The RCA's from the amp will be arn to the CD player, then you need to connect the speaker's wire to the output + and - of the amp, this will cause the amp to have musical power from your radio, and the speakers to have the power from the amp..-Shocker
Ground zero should be able to advise you on a power amp and sub.
If its a good after market headunit it should be ok, but an amp will always be the best idea.
A mono amp will not sound good with door speakers. There are to be used with subwoofers
Ohms is a measurement of resistance between the amp and speakers. Most home audio is 8 ohm, if you run 4 or 6 ohm speakers you cut resistance down and get more power out of the amp. Say your stereo is 100X2 @ 8ohm, if you use 4 ohm speakers you should get 50% more power BUT the amp is working twice as hard and can burn up.
Technically, yes. Any speaker can be hooked up to a car amp. Be careful though, car speakers aren't rated for that kind of power normally.
No. The radio or amp would be fused, but not the speakers.
Definitely make sure that the speakers you plan for the amplifier to power are strong enough to handle the amp. That means their wattage should meet or exceed that of the amp. Otherwise, the amp will blow your speakers. Also, it's good practice to use bass blockers on the front speakers. These are very inexpensive, and allow you to hear the high- and mid- frequency signals with more clarity while all the "boom" is in the back.
Hook your speakers up to the amp.
No that would neither be a good Idea or possible
