Just wondering what amp you guys recommend i have a kicker ZX650.4 and its not enough... I also replaced the massive tweeters with a set of mb quart ptk40 and they sound great but my mid bass is lacking...
If you're sealed and don't just have dampener then something is wrong. Granted, it'll still be somewhat loud without having something like mass loaded vinyl in there. I ran 300rms to them through the passive and they had plenty. They are power hungry, but that should be more than enough.
For about $100 you can pick up a 37.5 ft^2 roll of RAAMmat and have plenty to deaden the doors and then some.
From what I've heard about the RK6s, they put out plenty of midbass once the doors are sealed and deadened. Are your crossover points too high perhaps? If they're crossed at 100Hz or something like that the midbass will feel lacking. Try 63Hz at 24db, it may be that your crossover points are too high.
the tweeters was the first thing to go... haha I had them for 1 day and agree 100% they are harsh... I got a set of mb quart ptk40 and man they sound great for the cost... also i only have about 2hrs of play time on these so we will see in a few weeks how they sound
Are there some partsexpress tweeters that have been mated to the RK6 successfully? The weakest part of the RK6 are the crossovers making the tweets harsh. $90 for those MBQs is quite a bit. I'm sure there's some DIY tweets that would do well on the RK6 crossovers.
EDIT: Don't want to threadjack, just curious if you looked at any other more budget friendly options.
