Its funny. Everyone keep saing if you get in an accident its gonna exploed and catch the car on fire. Ok what do you think will happen if the battery is located inside the car. For example you get rear ended, The battery is gonna exploed with you in the car. Wow that makes sense!!

If you aint drag racing or a show car. You should leave in stock location!

Oh and i have mine mounted on the passenger side fenderwell also. Just get remote battery terminals and you go too go..
