do u think i will have any heat problems with the sirius modual under the back seat, the foam wont catch on fire will it?

 

it'll be fine...but why not just mount it in the trunk....it's not like you'll need to get to it often

 

i had it mounted to my sub box but it kept cutting out and doing wierd stuff so i decided to get it far away from the bass

 

I put mine under the passager seat. There is no chance of it getting too hot and no one will sit on it. If you have the 902, it probably wont get too hot, but the 901 has a fan in it which it relies on. Neither will survive if they are sat on, maybe even through the foam... good luck.
