im putting my old 15s SPL Dual Voice coil subs in the wagovan. when installing it tho ive run into some problems i just dont understand. now it could be something as simple as i need a new head unit because either this one is too old or the RCA jacks in it are shot. i dont really know, and dont know of where else to turn. ive got the power cable ran with a 100v fuse(fuse is not blown already checkd that) to the amp. amp is HIFONICS 1600 watt. has a good ground. sanded down to bare metal. when i ran the remote it was getting power but not much so i looped the remote and power and the amps got more power. next i ran the RCAs and there brand new. so everything to my knowledge is hookd up. amp has power and comes on but when i went to plug the speaker in.....nothing. so i thought maybe speaker was blown, untill i wired it up in my buddies car and it hits. sooooo......i really dont know if the radio in it is f*ckd or what.....someone told me to get RCA jacks for an ipod and hook that directly up to the amp and bi-pass the radio so gonna try that later. if anyone has some advise or knows anything to try please help me.....
