Posted April 27, 201015 yr I finally got my system bought and all put together today!!2 2 0hm 12 inch L7sKicker zx 1500streetwires powerstream 0/1 300A anl fuseoptima redtopso the problem is...i turn my truck on, system turns on fine, as i turn the bass up, it shuts off, i turn it down, it gradually comes back on after a few seconds. And does the same thing each time.i grounded it to the seatpost bolt ( which i found out briefly agok, IS NOT ATTACHED TO THE FRAME)i Wired the subs down to 1 ohm each, equalling a 2 ohm load, but the weird thing is, is that the12volt.com said to wire it one way (for 2 ohm load) and kicker said to wire another way??????so i went with this way- as oppossed to the kicker way. Why is my amp shutting off? bad ground? bad amp? bad wiring? please help
April 27, 201015 yr If you wired each sub down to one ohm then you are not at a 2 ohm load, you are at 0.5 ohms. Each sub should be wired like this:This way each sub is wired in series to 4 ohms, then when added together the load will be 2 ohms.
April 27, 201015 yr Is the Optima Red Top the secondary battery or the main starting battery under the hood? Have you done the Big 3 wiring?
April 27, 201015 yr Measure the voltage at the amp when as you turn it up and when it shuts off. Also measure the resistance of the load from the subs at the amplifier (all wired together).
April 27, 201015 yr Author Is the Optima Red Top the secondary battery or the main starting battery under the hood? Have you done the Big 3 wiring?the redtop is the main, i have no auxillary, and no on the big 3
April 27, 201015 yr That is your problem right there, there is no way a 1500 watt amplifier can get the power it needs to perform. You cant make power if you dont have power, you need to get: a secondary battery, voltmeter and do the Big 3 Wiring. What size is your stock alternator?
April 27, 201015 yr Author i really wanna add a secondary battery asap. and my alt is 105 i believe. there is 4 terminals on the sub, i wired it neg with white dot to red without dot. and red with dot and black without to amp. on both subs. could this be an issue?
April 27, 201015 yr This ohm thing is kicking your ass huh?Seriously, do some research and READ READ READ. YOu have been a mess since you started this and I woul dhate to see you blow your shit up because you are in a hurry!

April 29, 201015 yr i had a blown speaker this entire time cause im a dumbassLOL, you mean you blew your speaker because your a dumbass? Don't feel bad man, it can happen to anyone that jumps into something without doing their homework.
