I have a pair of 10" kicker comps powered by an alpine MRP M650 600W amp. I am having issues with the subs making a knocking sound? I figure they are clipping, but i've never really worked with subs before. Reviews on kickers site say the comps kick hard. Mine aren't. I had it installed by a car audio shop today, and found out that they had 2 bass boosts on (one on the LOC and one on the amp), and that was making the knocking, but when i turn it down so the speakers stop knocking on hard hits, I can barely hear the subs. Am I not setting up something correctly? I set the bass boosts down to stop clipping, and tried setting the gain lower so it wouldnt knock.
Are the knocks bad? did I buy POS subs? lol I'm aware I have a 600w powering speakers rated at 150 watts, but they are rated for 86 dbs which should be loud enough to have an affect on my system without crapping out I think.
Thanks for any input.
