Static speakers

[Brennan]

I originaly had the bose system in my camaro. A few weeks ago I replaced the front two speakers because I kicked one in. I used some alpines. Sounded better then stock bose speakers. Now today I went ahead a also replaced the head unit with an kenwood. I used a crutchfield Scosche OEM Amplifier Adapter to integreat the new head unit into the bose system. The problem is that the two front speakers have constant static. But the back three speakers which are original don't. Could this be caused by the ohm difference or is it something else?

The ohm issue "could" be the problem since the Alpine speaker ohms don't match the stock Bose speaker ohms.
Does your new Kenwood head unit have a built in amp? If so, you could use the Kenwood's amp to power the front Alpines, you'd just have to run new wires. The Ohms on the Kenwoond and the Alpine speakers would then match. To power the other remaining 3 rear speakers, keep using the Scosche Adapter.
