Hello all...this is my first post. I just bought an 05 f150 fx4 lariat 1st thing...I put a CD player in it..turned it on & it wasn't all that loud...found out there was the 8" sub under the back seat.. It's not working. I checked all my wiring..seems to be good Checked fuses...they seemed to be good Sooo...I need help to figure out why the sub isn't working??? What am I missing? Thanks Athens Staff
hgray Post up a new thread about yourself in the intro section. http://www.fordfullsize.com/forum/f6/ Check fuses/power to the amp. Check remote turn on wire (usually solid blue) from radio to amp. Sub wiring correctly connected to amp. Test sub, connect C or D cell flashlight battery momentarily across speaker wires, if popping sound happens, sub is good. RCA cables connected to back of in dash radio head unit. Sub is turned on in dash radio head unit menu selection. If all these check good and still no sound amp may be fried.
I'm not sure there is suppose to be RCA wires It's the factory sub that comes with the audiophile package It's a a hard plastic box under back seat Fuses are good I'm lost Athens Staff
I guess that's what happens when I assume you had an after market sub/amp. 2004-08 Ford F-150 SuperCab Car Audio Profile
Did your wiring harness kit have this 8 pin subwoofer harness included? METRA 70-5521 HARNESS Into Car Wire Harness
Ok I found the parts I need Just hoping the 12 to 5v step down comes with good instructions I have no clue on where to hook that one up too Thanks of your help Athens Staff
Sorry for the misunderstanding. Been a long last few weeks for me. Seems the 12v to 5v was only for sub popping sound your problem is no output from the amp/sub. I'd try looking at the 8 pin amplifier harness first.
