i was wondering what everyone thought of the Eclipse AV3423. yes i know that its non detach but i dont care lol. thats for any and all input left

It is a great unit. The only downfalls to it were a somewhat low preout voltage and lack of sub out, both easily corrected with a Audio Control 6XS.

if theres no sub out on the unit how would you hook up the audio control 6xs?? isnt it a signal booster ( i really dont know) if theres no signal to start woth how does it do it?

The 6XS takes the front and rear rca outputs from the AV3423 and then creates another set of dedicated subwoofer outputs from them. It retains full fader control on the AV3423. The 6XS then allows you to mount the subwoofer level control up front so that you have the ability to control your subs independent from the main speaker levels. The 6XS also provides you a line driver on all channels and a darn good crossover at the same time.

how would that work along side the rockford bass control?
