amp wiring location for mitsubishi

kahlilj wrote: i'm a newbie at this so please have patience with me.. i'm trying to install an amp in my 90 eclipse and am not sure where to penetrate the firewall to run an 8 gauge power wire. for any folks who have done this on similar car, where did u take your wire thru? an existing hole/location in firewall or did u drill a new hole? if u did drill, where would u suggest to penetrate to avoid any damage or problems?? i'm assuming since my battery is on passenger side & amp will be as well, that is the best side to run power wire thru right? thanks for your help!

Ok this maybe a newbie question but what the heck is a firewall.

The amp does not neccarassararrily have to be on the same side . it'd be great if the wire is not so long though. 

Then run the RCA wires on the driver side.

Not neccesarily, I just find that there is usually a hole already there or is easier to drill on the drivers side. Every car and truck is different, so just look around inside for the best route.

thanks guys. well last nite after giving up on finding an existing hole to run power wire thru, i drilled a couple of pilots holes.  i say couple because the the 1st hole i drilled (from the interirorpassenger side footwell area) did not show up in the engine compartment!!  i used a small bit size (~5/32" or so) and drilled right thru.  poked a hanger wire thru  at least 10" or so; looked in the engine compartment for it, but could not see it!!    

i am not sure if the hole was drilled in some pocket on the engine side of the firewall or what.  i'm pretty sure it did not go in the tire well area tho.  ...????

anyway i drilled another hole closer to the center of the car & slightly lower, but  SAME RESULT!!!???  i have no idea where this hole leads to. i saw NOTHING in the engine side even after poking hnager wire several inches thru.  what gives!?!?!?!  i feel like a dummy or something.  this should not be that hard!

i located what i thought was a clear area in engine compartement side just below battery level and its corresponding side in the interior; drilled and got nothing.  has anyone ever done this on an eclipse before??  or can someone please tell me how YOU determine the best area to drill thru firewall?    please help!! 

that's what i did.  unfortunately i must have been misaligned.  i even used a tape measure to get the vertical height (from the ground).  took that same tape and placed it in engine side on the ground to ensure it was about the same vertical height. but it seems myabe my horizontal distance was off??  any suggestions on how to locate the exact location when its only one person?
