The dsp is only if you want it, the Sony radio I installed in my other car has one but I rarely use it but it does have a front left and front right selection(along with a couple others) which does great for getting the center stage in front of the driver of front passenger but it is worthless if you don't position the speakers just right I installed my front tweeters slightly above my ear level in the a-pillars quite a painstaking process to get it just right in order for the timing to be just right for both balance from woofer to tweeterOriginally Posted by 2005_ESCALADE
The subwoofer needs to be crossed over or it won't sound right and can be damaged.
Also nice system I am using the stock radio in my truck and am getting great sound surprised me the difference (I hate Bose) even ditched the stock "sub" for a 8inch under the center as I like stealth.
Btw how does a three way setup sound as far as sound staging goes I am thinking of doing one sometime just have to decide on if I want ribbon tweets and mid's or dome's as I will be doing a custom setup.(leaning towards ribbon as my home audio speakers has them for the tweeters)
