i need help with my new system that i got going in my car i put in the new alpine 6 1/2 component set by the way they are very nice and sond wonderful if you are looking for a component set these are awsome and i also purt in a new apline CDA 9815 mp3 player. i installed the speakers with the crossover included and then also installed my deck not knowing there was a built in crossover. what im getting at is are the component speakers being crossedover twice and if they are is it affecting there performance. i and wondering what everyones thoughts are on this and what i can do to get the best sound quality. the deck also had a I personalized thing were you are able to load eq and crossover setups on to a disc and load them onto the deck so if i need a certain set up for the built in crossover to make the components do what they can i would love the help and thoughts... thanks and once again those compnonents sound awsome and the deck is a really fun toy to have there isnt anything you cant do on it
thanks

Sorry we missed answering your question... if you get down the list too far, and no reply, just add a 2nd post like: "BUMP ^" and this will take you back to the top of the list. Someone will catch it.

About your Comps, they have passive crossovers already and all you really need to do here, is determine what the lowest frequency the midbass driver can handle with clean sound. Most drivers of this size are best to use HU HP filter crossover between 60-80 Hz. The tweeter
already has its own "fixed" crossover point. So you don't have to do anything there.

If you have subs, these can be LP filtered at the amp or the HU. Most guys prefer 75-100 Hz. A little playing with the HU features will help you determine what sounds best to you.

I have been reading a bit on that i-personal memory preset down loads. Don't have any experience on how to use that feature to date, but if you read the users maual a while, am sure youcan get something useful from this feature.

Are you using the HU amps to driver your interior speakers now? Am not sure if this model has that special #10 gage power feed line and ~27 watts RMS/channel. If yes, may be adequate power for all but the least efficient interior speakers. However, if less than 20 watts RMS/ch, to get the most from these Comps, an add on amp may be a good option on the future. (50-75 watts RMS will do nicely)

Any more questions or comments?
