Mobileaudio25 Posted April 14, 2013 Report Posted April 14, 2013 I'm running 2 DD3512's firing forward sealed off. 180 amp alt, 3 agm batts all 0 ga wiring.... I was running 2 hifonics brz1200.1's (one on each sub wired at 1ohm) my subs are DVC 2 ohm. It was hitting pretty well i had a few people say between 142-144 if they had to guess... I wanted more power because my speakers were swallowing those amps so I bought 2 brz2100.1's and got them wired up today. They are turning on, not going into protect and im getting pretty much the same voltage at all fuses, batts, amps within .03 of a volt. My speakers are hitting no where near as loud as it did with the smaller 1200's and its on almost double power now ! another thing i noticed was at full tilt with the 2 1200's at idle i dropped down to 12.8v and with the bigger 2100's im not dropping below 14.0 on full tilt..... Any suggestions? Ive double checked wiring and everything. Didnt pull the speakers out of the box or change any wiring other than running 0ga for the amps and getting rid of the 4ga. Gains were set with a dd-1 with both setups and then gain matched with a DMM.. competition in the morning and Im clueless.... Any help would be appreciated.
russtezecustoms Posted April 14, 2013 Report Posted April 14, 2013 Could the polarity be reversed on the speaker outputs? Or one of the polarity switches fliped? ' Just s thought. I just wish i had a funny sig.
Mobileaudio25 Posted April 14, 2013 Author Report Posted April 14, 2013 The speakers are both hitting out and not in....

Mobileaudio25 Posted April 14, 2013 Author Report Posted April 14, 2013 Found it out.... Bad rcas. Something must have happened I have no clue. 145 db
z_jarad Posted April 17, 2013 Report Posted April 17, 2013 Man this sucks I have had this happen with an old system took me a few hours till I finally tested the rca's
Mobileaudio25 Posted April 17, 2013 Author Report Posted April 17, 2013 Yep, I was completely lost w cause it worked fine prior to switching amps. I was happy with my 145.0 spl score inTrunk 1 though getting a new alt and a tach , hopefully I can pull a 146-146.5
