INSTALL in my travel trailer
Hello,
I was hoping to use a couple of old 12 inch JB w1's in my travel trailer and some 3way 6X9 and a couple amps in my travel trailer the problem being how do you set up the conversion from 120volts to 12V or 14V i suppose. I know they make converters but can they handle such a load or power flow..... I guess Im asking how do the boys/girls hook up there power in the stores for there displays. I could make that happen if I know what they use for power conversion!
Thank-you in advance...
Tanner

The way i did it in mine i used a 12 volt car battery and a battery tender/carger and i have never had a problem works very well jsu about everything in our trailer runs 12 volt instead of 120 the first year we had it we were on a none hydro camp site lol so out came the wire battery and old car audio.I ended up doing 12 volt lighting as well works great and is real cheap now that we moved to a hydro site hope this helps

Your trailer should have a power converter built into it. The convertor runs off a 110v circuit from your shore power cord when you plug into a power outlet. The convertor will likely be rated at anywhere from 25a to 50a depending on the age and model. Assuming you have a battey connected, the battery is conected to a charge line from the converter so the converter will charge the battery when the trailer is plugged in.
Remember that 20a to 50a output rating of the converter cannot be sustained because the charge module in the converter will be rated for considerably less than the full output of the converter, likely 10a or so, plus anything else in the trailer that is 12v will eat into that available power as well.
Also if the trailer is an older model before days of electronic power converters, hum could be a problem originating from the 110v side of the converter.
What I would do is connect the head unit to the existing radio circuit power wires then run a 4 guage power kit up to the battey(s) to power the amp(s). If no batteries are on board then I think the amp idea will not work for very well.
You will need to supplement the charge module in the convertor with another charger right at the batteries.
