Re: Stereo Wiring Help Needed... '08 WK with RER/Boston System
The 500/1 is a bit overkill for that sub... Im running the 250/1 on my stealth box and i can easily max it out and im only at 1/2 gain... Just sayin! LoL
Your issue is with the canbus system... I had the exact problem when i first installed my system... thats when i realized the stock radio uses the canbus system to feed the stock amp. I would up using a $20 LOC off the rear channel of the boston amp to feed my 250/1. Works absolutely flawless
I even installed a sub level controller up front so i can independently control the sub and kill it when i dont want any bass.
If you want a cheap fix, ditch everything you just did... and run two LOCs off the BA amp to feed your 300/4 and use the pre out from the 300/4 to feed your 500/1. This will give you full volume control from your RER, but have everything powered on your JL amps. Just remember use one common ground point for your amps. I used one of the bolts that secures the stock ba amp as my ground point.
Hope that helps!
