I know this should be in tech but it's late and hoping to get help tonight. Anyways I have an alpine cda-9833 and an alpine mrv-f340 amp. Powering kappa perfect components up front and some kappa 2 ways in the rear both 6.5". If I turn the volume past 18 the speakers go out and the blue light on the amp turns red. My other amp and 2 subs work fine just the speaker amp cuts out after 18.
