my wires for the amp is real clean.. like i almost did the same thing u did but i went under the trim and then pulled back carpet up and went under that to the middle of the seat then went into trunk and for the ground i took the carpet up and put it on a bolt then put the carpet back were did u run the power wire because i had to drill into the wheel well and then back into the car on the passenger side but you can barely tell the wire is there
