Just by the gain adjustment itself. Should be around 2/3 of the way up..visualy it looks about even. but if it were just a hair off between amps, it wouldn't cause the difference that im seeing. Were talkin about a huge difference in volume between the subs when played...i did swap subs to be sure it wasnt a coil. when I first hooked it all up the excursion of both subs when played was even. I heard it fail that day. it was loud and then I heard I difference all the sudden. I looked at the 2 subs n one was moving way more than the other. I think If I order a dc or crescendo amp im gonna order a smd gain setter also

Yea I unmounted them n swapped em n I plays low on the other sub too. I even hooked up 2 12s n a box. one sub to each amp, one hit alot lower than the other. Called the ebay seller today and the are gonna let me return them Thank goodness. Im gonna run both on a Crescendo bc3500 at .5 ohm n be done with it. Shoupd sound better with that amp anyway.

i see what ur saying. but when i first hooked it up, they sounded and looked like they were hitting the same then all the sudden there was a huge difference the way the 2 subs were hitting. to match the excursion by eyeing it i had to turn the gain down on the good amp almost all the way to mach the bad one. i know there shouldnt be that much of a difference

i hooked up 2 PSI 18S and 2 Soundstream tx1.2000d amps. Gains and freq levels were set the same on each paired amp n sub. The first lil while i played it, everything worked fine. then all the sudden i notice one sub were playing lower than the other. wtf right...checked the impedance on the coils and they check out fine. So over the last few weeks ive done everything i can think of from checking connections, swapping subs around, new rca cables, even thought it might be the bass knobs, and still one of the amps is putting out less power. I can tell there is an issue because when i play a test tone, what ever sub is hooked to that amp suffers especially in the low range 20-30hz compared to the other sub n amp that is playing at the same time. i called Soundstream and they said it either plays or it doesnt, theirs probably nothing wrong with it...wft i duno what to do. has anyone ever ran into an amp like this? i know somethinng is wrong with it even if it is playing somewhat. im def gonna try n return the soundstream amps again and get a Crescendo 3500 of SSA that ought to take car of the issue haa

yea i saw that the Zcon 15s require about the same box space as icon. so i could def sell the icons later n upgrade woofers n still use the same wall... kool

i have a 98"GMC ext truck that im going to wall off soon. i was wondering what set up would be better. 2 SSA Zcon 18s 2250w rms each= 4500w rms 4 SSA Icon 15s 1250w rms each= 5000w rms i have room to build either set up and lets assume i have the alt, amps n batts to push it..

thanx for the advice Truconcept

thanx for the ideas )

do you know anywhere i can get a used amps?

ok kool

probably like $600 max as of now and i need that amp or amps to push 2 2250w rms subs

I was thinking of getting 2 SSA Zcon 18's.. im tring to keep a budget, so for now i was gonna run a Hifonics Brutus 2400.1 on each sub until i can afford better amps...The are supposedly CEA certified.. any thoughts???? Are they worth a crap?

im thinking about getting 2 zcon 18's next week, but for now i was going to go with Hifonics amps until i can afford a better amp. Was gonna run each Zcon on a Brutus 2400.1...They are supposedly CEA certified. Is anyone running Hifonics amps?? Are they worth a crap?

yea ive heard that SSA is really underreated. i might go with an amp on each sub that puts out 2500- 3000w rms or so each. And a wall with just two 18's? ok

I am planing on getting SSA 2 Zcon 18's and a Crescendo 3500d next week. I have a 98' GMC ext cab truck. What type of set up is best in my vehicle? wall? ported box with subs up? subs forward?... need some advice..
