yea im building a box today for them, im thinking my port was way too small and not getting enough air movement

yea ive been having nothing but problems with these subs so im thinking about upgrading soon, but right now im just wondering if the sub that is getting warm is the only one getting power, and the other one isnt, my box has both subs vented to a single vent so maybe the air was moving my one sub that wasnt getting warm and it made it look like it was hitting, from what ive been reading it is normall for subs to get warm, i would try to hook them up seperate but i have them inside the house and out of the box right now

if the way you have shown on the right is the only way that works, im thinking one of your coils is blown out, any the way shown on the right is pushing one coil at 4 ohms, the second coil is getting no power this way (the coils are not connected internally)

ok i just checked my voice coils with a multimeter, and each of my coils are reading 3 ohms, not 4??? is this normal

maybee one of the voice coils is blown out and and not completing the connection with the first way you explained, but when you hooked the positive and negative up to coil one it might work but maybe its just bumping on one coil, not sure though

i would have did it all the same, but 8 gauge wire wouldnt fit into my wire terminals on the box

i have a two channel amp, but i bridge the subs at 4 ohms (each dual 4 ohm coil sub wired at 8 ohms then bridged at the amp for a 4 ohm load) i have 10 gauge running from the amp too the box and then 8 gauge from the box to the subs, all wires are the same length

they move the same, no distortion with either speaker and the both hit just as hard, and there is no burning smell, just gets warm

ok this just started today, one of me subs is getting noticably warmer than the other, they are both wire exactly the same but after bumping for about two minutes the cone on one sub is warm and the other is cool to the touch, what would be causing this, and also nether of them are blow they sound perfect

ok thats what i thought, so i should leave the subs wired at 4 ohms each and bridge it at the amp and it should give me a 2 ohm load, or is there any way i can run two dual 4 ohm coil subs at 1 ohm on a mono amp?

and one more quetion, a bit off topic but if i have two subs wired for 1 ohm each and i bridge it at the amp does that give me a 1 ohm load on the amp or a .5 ohm load?

oh that makes sense, so bridging it on the outside is doing the same thing?

ok this may be a stupid question or im just to dumb to relize the answer to it, but on my buddies crunch 1500.1 mono amp, there are 2 sets of speaker outputs, if its a mono amp why are there two sets ? can anybody explain this to me?

to tell you the truth, im not really sure about that, but im dont think its the headunit if thats where you are going with this, but to be sure ill try it im my buddys car tommorow

yea i checked and the subs were wired for 4 ohm load all together at the amp and my amp is 2 ohm stable, so yea the amp is prolly just junk now, but that gives me a better reason to go and buy my friends 2000 watt hifonics off of him, the only thing that bugs me is id like to know how an amp just decides to go bad from sitting overnight, but thanks for the help

yea grounds good, bare metal, 4 gauge from the amp to the body, 0 gauge from the battery to the body, and DMM says 14.6 volts at amp

i unhooked the subs from the amp and the protect light stays on so im thinking my amp is junk now

Oh yea, sorry i forgot about that, its an SPL Z2X-1600 watt, I know its a cheap model amp, and people are going to say thats my problem, but thats not the answer im looking for

ok first off the amp was fine last night driving home, was bumpin fine, i come out this morning and get going and i dont have any bumps, i stop and i figured maybe the power wire fuse might have blown, nope that was fine, the amp fuses were fine the grounds are good getting a full 14.6 volts at the amp, but the red protect light is on, not really sure what would cause this from sitting overnight, so i hope someone else can help me

looks good, i was just wondering what program are you using to design the box?

i had the same problem, mine would be quiet and them whenever i hit a bump in the road it would get loud, i solved my problem by putting some dilectric grease on the ends of the rca's going into the amp, after doing that i havent had a problem since, although a new set of rca's is probably the best way to fix it
