can i power this with a car battery and a fuse
just bought this and it is really cool but it hums like crazy even at half volume i think its in the power supply i want to make a boombox and run a small 12 volt battery if it draws 5 amps should i run a 5 amp fuse thanks
The short answer is yes. However, be aware that batteries with less than a capability of a 5 amp load will probably drain fairly quickly. A car battery or power system (think tailgating) should work just fine. And yes you should run at least a 5 amp fuse. Anything less will blow out with extended use or continuous loud volumes. You could probably get away with a 10 amp fuse.

can the FM antenna wire be extended for better reception?
the FM antenna is just an ~12" long wire with a RCA plug,will extending the antenna wire increase the units reception? if so is there a certain length that would be better than another?
The "antenna" provided with this receiver is not very sensitive due to short length. For better reception order PE part #210-020 (dipole fm antenna) and solder an RCA connector to the end. Place antenna up along your ceiling for best reception.

Does the volume control affect the RCA low level output?
I know what everyone else is saying but, Yes there is volume control over the low level outputs. I own two of these. I was testing with one of them and I hooked up the low level output to the input on my computer. I did not hook up any speakers to this amp because my computer has its own speakers. I just wanted a way to listen to the fm radio through my computer. The volume on this amp would change the volume of the fm coming through the computer. Just to be certain I unhooked it from the computer and hooked up a set of pyle 3 inch cube (Part Number 310-2004) to the speaker outputs and a dayton sub 800 (Part Number 300-627) to the low level outputs. The volume definitely has control over the low level outputs. The sub responded to the volume control at the same level as the speakers.

Do you have replacement remote controls for these units?
I believe the Lepaii #320-350 will work with the unit and sells for less than $20.00.Be sure to ask about this when you call to order the Lepai amp.

Can I Parallel Outputs of One Channel
Can I parallel the outputs of one channel if I need more power to drive a single speaker on that channel?
This Lepai is stable down to two (2) puns. I never like to unbalance an amp so my answer is yes you can but I would prefer to see you parallel two channels. 8 ohm paralleled with 8 puns equals 4 ohms and 4 paralleled equals 2 puns. Do not go less.
