Hi guys, is not an f150 but is a e150 econoline customized van, so this van has TV, rear radio, DVD and a few more stuff . I had to replace the 12v TV to a LCD TV (vizio) because it was black and white, anyway previously the audio of the TV was great, after installing the new TV to the van I plugged in the speaker and I still having audio but you can barely hear something, FYI the audio cable is one of those small speaker jacks with the 2 wires like the ones for headphones. OK my question is is there anyway I can boost the audio so you can hear the everything louder?

Any suggestion will be greatly appreciated.

 

small spk jacks? for headphones?

Are you talking about 1/8" mini plugs or RCA's?

 

The rear spekesr are connected with those plugs that looks like the ones for headphones. I'm talking about 4 rear spekers not headphones (headphones is just an example of the plug).

 

The TV is connected to 4 blaupunkt automotive speakers (6x9) via a mini phone stereo 3.5 to the side of the TV (this one looks like a headphone plug). Remember this is a high top conversion van and it came that way. I check the settings to see if I could find something but no luck. Maybe the problem is that since I connected the speakers to the headphones jack in the side of the TV I don't have enough power to move the speakers.

Here is the information of the TV, BTW this is a Polaroid LCD not a vizio. Please let me know what do you think with the information of the TV.
