Hi, i'm thinking of switching fro my cda-9825 head unit to the cda-9855 with the 7 channel eq , 4 volts from 2 and alot more features. will this add power to my amps i have the mrv-f345 along with mrd-m1005 and type x running off that. will my sub get louder not just from the 4 volts but just from having a eq when right now i dont have an eq. please help.

Won't make a bit of difference. You will have a few more features to play around with, but the volume will only increase with bigger amps.

Read the "Preout Voltage" thread in the Amplifier Forum cause I'm not going to go through explaining it again.

you can see a difference if you completely switch brands. what are you looking to change?

i was just wondering if the eq will help me set the bass better

yes it will be a difference dunno how big because i don't know how you are going to utilize the HU. if you were to say get an active frontstage then yes, it will make a big difference but not quite sure how you will utilize the HUs capabilities? what exactly do you need to control the bass better?

i just switched my cda-9825 out with a cda-9831 and i can tell a big difference. Also the 9825 can't play mp3's. it didn't make my system louder, but it does sound alot cleaner and i can adjust the eq to sound better. The cda-9831 is a big upgrade over the 9825. I would take a 9830,9831,9833,9835 over any new alpine deck. i do not like glide touch and the new ones have less features for the same price
