I have just replaced 2 of my 12inch subs with another pair of SAME RATED subs and I am getting dramtically LESS AUDIO. What's this all about?
I do have a basic system ~ here it is! Perhaps someone could shed some light on this!
Amplifier: Pioneer GM-X802 (7 years old) 2CH 100W x 2 @ 4 ohms RMS 1CH 150W x 2 @ 2 ohms RMS ~ (amp is 2ohm stable)
Original subs x2: (7 years old) Rock Fos RFP-1812 12inch 8ohm SVC 200 RMS/400 MAX
New replacement subs x2: (new) Rock Fos P212S4 12inch 4ohm SVC 200 RMS/400 MAX
I have kept the wiring the same in parallel after installing the NEW subs. I thought for sure using 2x 4ohm subs in parallel (2ohm load) would be louder/powerful than my original setup with 2x 8ohm subs (4ohm load).
BUT THESE NEW SUBS ARE SO QUIET.
Any ideas???
My guess is these 2 new subs are "under rated" and I need a more powerful amp. Perhaps 300 RMS to each sub?
