okay so im running 2 12 inch alpine type E's and one polk audio dxi 4 ohm on a 1100 watt mono boss audio amp but when i turn up the volume to much the amp goes in protect mode is it cuz im overloading???

seems reasonable... is the gain turned up all the way?

what are the subs rated at?

ohm load for amp cuz if you have them wired like so:
that could be the problem
thats assuming they are all 4ohm SVC

First and foremost...
Gain: It is not a volume knob. Gain "matches" the input of the amp to the output of the head unit/stereo.
Alright, now the issue. Most likely your amp is going into protect because it's clipping. A clipped signal is basically a sine wave. Not only that, but a speaker "load" actually changes based on temperature, frequency it's playing, etc. So your amp isn't "seeing" a 1ohm load. It's all over the place...
In addition, you need to verify that all 3 subs have 4ohm coils. After you verify that your speakers are 4ohms a piece fix your gain. Clipped signals destroy pretty much everything in car audio. If you ever had a friend and their equipment failed...most likely it was from a "clipp'ed" signal. 90% of car audio failures are from clipping. Owners are just ignorant as to what happened and it's always "over powered" this or "under powered" that...Luckily you're a smart dude!! You have a an amp w/ protection mode
Sorry if I came off as brash...I just like to be direct

Unless you have oldman's syndrome.
"not loud enough, turn up the volume, just a little more.... a touch more..... *BOOM* damn...."

i have them running as positive to positive and negative to negitive and i twisted the three different postives together and same with negatives ? is that an ohm overload?
10-25-2010
Yes, unless your amp is stable to run at 1ohm... Thats like what they pointed out, with them wired like that your at 1.34 ohms and most good amps are only rated to run 2ohms or higher. Cheaper amps are rated at 4ohms and will overheat and go into protect very easy when running anything less. So either turn the **** down, or buy a super amp that is 1ohm stable. Or wire them all into serries which will give you 12 ohms and put out very little power but your amp will be saved. 3 is a tricky number which is why its not a common setup...

Look into an aq amp if you wanna keep running it like that then. I've had mine down to .7ohms with no problems at all.

lol i have my 1200Ds strapped at 1ohm so each amp sees .5
i've also had my old hifonics 1606D wired to .5 for daily then had a fellow bass head wire it to .33 burp and get 23xx watts out of it lol
go class D regardless

Unless Im missing something here why 3 subs that dont match? and odd # subs always create ohm load problems unless you have a good amp that can handle the low ohm load why not just run 2 subs and each of them getting more power, a more stable ohm load, and turn the gain down. Again its not a volume knob like the others said. I highly suggest looking into learning how to "clamp" and amp thats the only correct way to run and amp.

okay what i did i found this wiring diagram and i wired them to a 2.7 ohm load and because i got 2 subs for christmas and i bought one at discount price at work
11-02-2010
1 of 2 things.... you have something wired WRONG or the wiring is correct and the amp cant take the ohm load... ok 3 things.. LOL the type E's are 2ohm... cant mix and match subs(diff ohms)
11-02-2010
there could be other stuff wrong also... gains and xover settings, start with the wiring first
