Ok this is the frist F150 that Im mounting my amps behind the rear seat. My question is should I mount them on a amp board or can I just screw them to the parts of the back wall that stick out? Which would be better?

 

I think ever one has used a board. It's the smart thing to do.

 

I have a standard cab and the peeps that did my install just mounted to the back wall. Thats all great until you want to change something then have holes. Id mount them to a board, gives you room to be flexable and to change later with minimum holes. Im about to redo mine.

 

some amps dont react well to being mounted to metal....could cause floor noise.....not all amps.....some....

 

Every amplifier instruction manual I've read say not to mount the amp to metal, but to mount them to a board. Noise being the main reason.

 

yep.. the potential is there.

 

what exactly is floor noise

 

usually ground loops. more than one path for ground. interference, signals, etc.. picked up through the ground..mount a metal amp to metal is like adding another ground

 

ahh that might be my problem i am having with my alternator whine i will go pick up some MDF and remount my Amps this weekend when i rewire my system
thanks for that explanation JJDH

 

definately be sure the ground is good, rca's seperate from power wires.....etc

 

i mounted mine right to the cab wall. but there was the wall linig there from the factory so thats the only thing between the wall and the amp. a board would of taken up to much room for me. space was critical.

 

i am right there with you my amps are pretty thick but i hope once i remove the lining behind my seat i can mount mine with a thin piece of MDF or something along those lines

that is why i am rewiring my system grounds are good wire locations and routing not so much :o

 

i used 1/2" oak plywood from homedepot and wrapped it with fabric from joann fabrics.(the wife went with me)

 

alright cool i will try some of that if i cant find anything around the garage thanks JJDH

 

Well I mounted my amps to a peice of wood just used some 1/2 plywood which made it easier to mount the amps Now I have another problem the box i got out of a trade in at the dealership I work at came out of a chevy but fit prefect in my truck then I bought a Kenwood sub put it in the box and installed it in my truck and my sub sits right on the carpet. So now I have to figure out what Im going to do about that. Any suggestions?
