Thread: Wiring Diagram of Inverter and AMPS. Will this work?

1. I know it's undersized, but what are the negatives to powering the entire setup (400watt inverter, 2 amps, and computer) with a single 8 guage wire

Too little juice going to all the devices. Run a larger cable, you're better off. If the 8ga is already there run a separate lead for the inverter since you'll probably want a relay on that line anyway.

2. What are the disadvantages to running 6 small stock speakers off a 2 way amp?

To low a load for the amplifier would be a big draw back and will probably make the amp shutdown. Draw back #2 is most factory speakers are only designed to handle about 25W Max. Add some distortion in there and those speakers will be toast in a hurry. Check the specs on the amp before you connect it to make sure it'll be stable. Also check the impedance on the factory speakers, it's possible that the tweeters and front speakers are wired together to create a 4 ohm load in which case if you wire the front and rear channels together in parallel you'll present a 2 ohm load to the amp which is probably well within spec for that sony amp. Beware though that your power rating is probably measured at 4 ohms and should be 70x2 @ 2 ohms.

3. Is there a way to have the Inverter turn on with my car key? It has no REM wire. Also, I prefer to leave it on 24/7 as long as it won't run down my battery when the car is off.

Yep put a relay on the power lead so that when the key is turned off it disconnects power from the inverter. I've run my 300W inverter for 4 hours without it killing my battery, however it was a brand new battery at the time. If you want it on 24/7 get an opus, it won't draw nearly the current that an inverter will.

Thanks for the help. So do you think I would have enough power using one 8 guage for the Inverter and a separate 8 guage power wire for the 2 AMPS? Also, where can I get a relay, radioshack, oreilly's? and how do I wire it up to the ACC. I've never used a relay switch.

Lastly, so I take it if your inverter is directly connected to the battery and left on, eventhough it is not powering anything, it will still drain your battery in a few hours.
Thanks.
