Hey guys, I was wondering if i could get some help. Ive got a 2007 M45 sport infiniti. I have everything i need. I have a 4 gauge rockford fosgate amp kit. I have a t1001db amp, a sealed t1 series 12 inch sub. a 10 farad capictor by rockford fosgate along with a kit for it.. Well when i went to do the install of the amp kit the other day, i couldnt find a hole to run the 4 gauge wire through from under the hood to inside the car. Can anybody help me out with this.?  I have a capacitor i bought used then 10 farad rockford fosgate. Only thing is the guy i bought it form didnt send me the charging resistor? Is there anyway to get around this? i also have a MTX REQ 3. And I was wondering should i pull off the back left or right passenger side speaker or should i run it off the factory bose subwoofer speaker? Thanks in advace guys!2007 Infiniti M45 Sport
