MAJOR PROBLEM...help me out

[michaellane 5,000+ posts]

first off i drive a 2002 accord. 0 gauge welding cable and a big c&d battery in the back. //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif:crying:

i have four of these subs pb10-4

http://www.credencespeakers.com/Clearance_Corner.htm

my box is 25" deep x 27" wide x 14.75" tall

i have one 6" aero port that is flared on both ends. the pipe in between the ends is 6" long. the port fires into the cabin/car and subs are m0unted on top of the box. the port is smack in the middle of the back board (27" X 14.75")

i also have a nine.4 that is working great!//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

well my subs are single 4ohm. i wired them up to have a final load of 4ohms (checked with DMM).

next i ran the positive speaker wire to my FIRST/MASTER nine.1....then the negative speaker wire to my SECOND/SLAVE nine.1.

so each amp is seeing 2ohms. o out put should be roughly 900--1000 per amp. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

now when i play young jeezy welcome back it sound like complete crap. almost as if they were being under powered. if i turn it up like i use to it sounds crappy and the subs almost bottom out AND is NOWHERE NEAR AS LOUD AS IT WAS BEFORE I ADDED THE SECOND AMP. why is this? what have i done wrong???? when i ran them off a single nine.1 wired to 1ohm they slammed, now its crap...//content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif:crying:

both amps are set right as far as slave and master.

no posative from box to master amp then negative from box to slave amp

am i right that the slave amp will have all the same settings gain, lpf, ssf as the master without changing anything on the slave amp correct?

how are they wired for master/slave? I've only done AQ/Sundown amps, so not sure if yours are the same.

NEG speaker wire goes to POS on the Slave amp. NEG's from both amps are connected. RCA's into the master and a single RCA connects master/slave...

yes, master controls everything, slave settings make no diff...

try taking one amp out and running one.. if its louder or better you are doing something wrong.
