Kicker ZX750.1 @ .5 ohm ???

[psych0ticnemes1 5,000+ posts]

I purchased a BNIB Soundstream T4 from a local dealer and he said it is a dual 2 ohm sub. So, I wired it to 1 ohm (because I have run this amp at 1 ohm many times for 10-20 minutes and the amp never became more than warm).

Well, I glance at the box and it reads Dual 1 ohm, which means I have the sub wired at a .5 ohm load (if it is indeed a dual 1 ohm sub) I have not put a DMM on the coils yet, so I'm not positive of the coil configuration... YET.

I ran the amp at this impedance heavily for 20 minutes before I saw the actual coil configuration on the box. The amp was barely warm at this point but the sub, rated at 900 rms, was bottoming out slightly at near 3/4 volume! This obviously alarmed me because this amp should not be bottoming out this sub. I have the gain set to a 1/3, which is where it should be for a 2 ohm load.

My questions are:

-How much power might the sub be seeing at .5 ohm if the amp is rated at 750rms @ 2 ohms?

-If the amp doesn't get hot, am I still damaging the components?

I will check the coils with a DMM (if I can remember how) and re-post later today.

Thanks!

check the coils, that amp should go into protect at 0.5 ohms. I don't think anyone has ran that amp at 0.5 ohms, so it will be hard to know how much power your getting. i could guess in the neibourhood of around 1100-1300 but thats just a guess. Yes you are still damaging the components if its being ran at 0.5 ohms even if it doesn't get warm. Check the coils and if they are dual 1 ohms than wire the sub for 2 ohms and call it a day.

WOW it IS dual 1 ohm... I am very impressed with the ZX line of amps. It played heavily for 20 minutes at .5 ohm without getting more than luke warm.

Needless to say I wired it in series for a 2 ohm load, but it is still impressive!

i was getting ready to ask why you werent wiring it at 2 ohm
