1000w Amps cutting out on me....HELP!!

Try turning your gain down on your amp and if it stays on longer than usual, than your ohm load is off, if its shutting off on a big bass note double check your connections make sure there isnt like a strand of wire touching the other terminal

sorry for the delay in response, im at work. just got done installing an 2channel amp (not mono) in a tacoma. i dont know what slammedyota91 is talking about....i dont think he does either...no offense. heres a link to how to wire a dvc sub in either series or parallel. you gonna end up either having to run the amp mono and the sub at 8ohm which will have no power, or run the sub at 2ohm on one channel. the amp will run 2ohm stereo which means 2ohms per channel. or one voice coil per channel and that will run the amp at 4ohm stereo.

<img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) --> hope you figure it out

thanks guys for the info, tomorrow ill hopefully put the sub back in the trunk and connect it and see how it goes.

ill get back to you mikey asap.

1) you can run a 2 channel in mono mode. but it is not a mono block amp. mono amps are bridgeable, you do the bridgeing at the speakers. bridgeing by the simplest terms is a means to drop the ohm load.

2) just for future knowledge thats not what a capacitor is for. its a power storage device. the real reason for it is for the amp to draw power from it instead of the cars battery thus keeping the amp at constant voltage and also to decrease other things like headlight dimming and voltage fluxuation. im not gonna get into who knows what. im just correcting wrong info.

if you want some pretty good info on ohms law and wiring in series and parallel check out . they have alot of good info on their site.

Use a multi meter and OHM your sub, meaning test the sub at the connector on the box:

if it says 2 ohm, unbridge it. 2ch amps cannot run bridged below 4ohm

if it says 8 ohm, you can bridge it( but then this means your amp is probably toast, maybe from runnin 8ga ground with 4ga power.

if there is no ohm reading then take the sub out of the box and test the coils. possible one coil is bad or a wire came lose. If you still get no reading then the sub is dead.

a 12 volt car electric system works in a reverse loop (thats why when your read in the repair manual every time to disconnect the ground) .... its kinda hard to explain...... but the ground is more important then the positive connection.... its not a good idea to run a ground all the way from your amp to the battery.... thats to far for the current to have to travel and will cause the wire to build heat..... the best thing to do imo is use the same or larger gauge wire that you used for the positive side for the negative side...... the boss bl1000 is bridgeable and will run a 2 ohm load but not while bridged..... depending on how you have it wired will depend on what kind of ohms the set-up will need.....

# Minimum Impedance Unbridged 2 ohms
# Minimum Impedance Bridged 4 ohms

with the minimum impedance bridged being 4 ohms and your sub is dual 4 ohm..... if you have both sides of the sub bridged to the amp its pulling 2 ohms which isn't a safe load.... which is more then likely the problem your having.... so id suggest wiring one side of the speaker to one channel and the other side of the speaker to the other channel....

This last post is the only one that is accurately explaining the problem and solution. Chances are inside the box the sub is wired parellel. If you open the box, and run it series, then the problem will go away. Problem with doing that is the amp will not be putting out it's full potential power. You either need a dual 2 ohm sub or another sub, or a mono block amp capable running 2 ohms
