Help!? Alpine power pack
Recently after my research on here I purchased a alpine cde-147bt headunit, alpine power pack and Polk db 6.5 rear 5.25 front. My problem is I turn it up too about 23 on the hu then after bout 10 secs the hu turns itself down then back up to 23. I didn't solder my wires and I only used that strap on the back of the factory radio as a ground. Do I need a heavier wire for the amp? Better ground. Also I adjusted my settings on my hu I set the frequency to 50 hz for front and rear and it didn't seem to do it anymore but I have never had to do that before on anything.
