I have put a flip down screen in my ford expedition . Stock radio put a fm modulator . The problem is that its making a nosie . The guy at the radio shop told me i needed a new aftermarket headunit. Can I upgrade the fm modulators they put a cheap one in with a filter. Thanks for reading.
I have 2 12" hx2 subs that were free . The problem is that one of the sub is 4ohm and the other is 2ohm. If I hook them both up in parallel what ohms would that be. Is there a way i can hook them up.
