Hey Folks I am getting ready to install a R.F amp and speakers to the stock head unit. Just wanted to get a little help along the way. I get the running power and ground to the battery. Just need a little help with the speakers. Its a four channel amp the R.F.-300x4. How do I go about tying in the speaker from the Head unit to the amp to the speakers. Thats where I am getting tripped up. If you have pics or a video that would be awesome. Thanks guys this site is amazing, your all a huge help!!
