The Nissan Path

i have the normal stereo not bose system, and am wondering if theres a way to get an amp installed without cutting into speaker wires to rca connector thing (already did this once and fried my gauge cluster somehow and cost 1600 to fix, not trying to do this again)

I make this recommendation to a lot of people: go to Crutchfield.com. I've done business with them for over a decade. They have great sales help and tech support, usually provide instructions and adapters with the items they sell, and the prices are fair. If you call their sales dept., just let them know what you want to do and what you are looking to spend and they'll give you some options that'll work for you and can answer any questions. They are also great if you have any warranty returns as they'll have all your purchase information if that time comes.
