Valentine 1 Remote Speaker
Can I wire the V1 into the factory speakers using the V1 Remote Audio Adapter ?
OR
I have a 9 volt battery operated speaker that I want to add to my V1 using the V1 Concealed Display and the V1 Remote Audio Adapter. Can I wire in the speaker to the car so that it does not run off the 9 volt? What can I do to convert it? I do not want to manually turn on this speaker all the time. Thanks....

you sure can.
1-- you can wire it in but it wont play over what you're listening too, it would have to be dedicated to the aux input and it would be the only thing that you would hear while it was switched on...this isn't what you probably want.
option 2... do you know how to solder? if you get a voltage regulator and a small capacitor you can step down the voltage of the 12-14.4v to a consistant and filtered 9volts

you'll need a LM7809 voltage regulator (found at radioshack for about 2 bucks. and a 220 uF Capacitor (about the same price)
connect the 12v feed to the Input pin, connect the ground to the Common pin and then when you turn on the power, you get a 9 volt supply from the Output pin. the capacitor goes between the 9 volt output and ground. then wire the poss. the lead at the capacitor is going to be a clean/stable 9volts, wire up your amp and you're good to go
oh, and congrads... you just made your first regulated power supply :-D

You may not have to go thru all of that effort to make a regulated power supply for such a simple device. If its not doing a significant amount of internal switching in general (ie:has a microprocessor of any programmable sort) then you dont need to regulate it, just an in-line 1/4 watt resistor, you can pick up at Radshack for 30 cents will work.
Now im sure someone is going to argue this over with me, but just think about what I said first. Ive used this same method plent of times, most electronics already come with a dc to dc converter, especially if the device was originally used in conjunction with a "black box" power supply plug, which looks like the thing you plug in the all on your xbox. Even if it was originally battery powered, it should be allright. If your device acts squirly with a non-regulated input voltage, then by all means do what Scott said, make a mini power regulator.
www.the12volt.com has 12 volt resistor application charts on what resistor to use at what applied voltage and what final voltage application. Pretty easy to read charts.

yeah, resistor may work just well... maybe try that and if that has amplification spikes when you punch it (may not be a bad thing) then go with the regulated power supply. they are both easy and cheap. if you go with the resistor make sure you do the calculation for 14.4 volts and not 12.
edit: actually.... personally i'd go the regulator route first... it's cheap enough and it's only one more wire then a resistor. you probably dont need the capacitor. This will ensure that the volume doesn't drift like with a resistor.

Or Sorry, but I had another idea that I wanted to run by you. Ebay item number 5746044913 is a BELL 12 V DC POWER CONVERTER 1.5 to 9 VDC. I think I can use this then wire into the car instead of using the lighter. Is this possible?
I'd appreciate it if you could tell me the part numbers. Again thanks, Adam
