I just picked up a used Palomar elite 400 hd with a cooling fan. I am planning on putting this in my truck to replace the little 100 watt box I am putting in the wifes truck. I have a Uniden PC78 that is supposed to be peaked and tuned and a bone stock Cobra 29, I assume the 78 will be too much but what about the 29? Or do I need to have the radio tuned down to run this? Is there any tips or sugestions on this amp?
