Lepai LP-A68 Digital 2x15W Mini Amplifier with Remote USB MP3 Media Card FM
Hi, I have a Van and will like to know if I can connect any of this amp to my car.
Any amp that can be powered via 12 VDC can be used in a vehicle.

Would it hurt the amp to wire two 8 ohm speakers into a 4 ohm load (Dayton 2-1/2" full range) to run off one channel while running a single 4 ohm speaker (Dayton 4" mid woofer) off the other channel?
It will not hurt the amplifier, no.

Can you safely tie the two "-" output lines together and run the output 3 wire (L, R, common)?
Yes, the common is the same

Does this amplifier have line out?
No, this amp has many features, including several inputs. There are,however, only one pair of outputs and those are 4-8ohm speaker jacks.I assume you want to use this unit as a head unit and plug it into another amp or sound system. There used to be an adapter for car stereo output to line impedance to allow connection to an amp, but a very quick search online came up empty. There also used to be amps that input speaker level signals and boosted the wattage. I don't know if that would do what you need. Personally, I think you'd be better looking for a different unit. I do have a friend that used a car head unit with similar features and hooked it to his home amp. I would not call the results audiophile quality but it did sound good.

Could I power this amp with batteries?
I am trying to build a portable iPod speaker system. This would do the trick, however, I am trying to use some rechargeable batteries in series to power it to make it completely portable. I may be getting in over my head. Any ideas?
Yes, as long as the sum voltage is a stable 12 volts DC it will work. 8 cells add to the correct voltage but it won't last long on a charge. You could parallel groups of 8 but if going to the cost and weight of that many batteries, look at PE's lead sealed batteries. They will last longer. Just balance the amp hours against the weight( how much are you carrying this device). Figure an approximate 2amp per hour draw times the time of use per charge. I am working on a similiar project and will use these lead sealed batteries. Have fun.

Is This a Class T Amp or Class A/D? If Class T, what is the amp chip used?
Since the catalog page does not specify the class or chipset, I would guess it is held proprietary by the manufacturer. Today a lot of pre/power amp chips are available for use in various audio products. At this price point few can quality compare. Read the reviews, I think at 2 x 15 watts it is hard to beat.
