I have 4 mtx 4000s and one 15 in the back of my hatch, but they keep shutting off due to the amp heating up. is there any way to keep the amp cool? and i need to get another amp and cap, who makes good amps and caps that wont break the bank? i need about another 1000 watts of power to push them to their fullest.
thanks

 

How are they wired?

 

i actually ran them kinda wierd. i lost the screw to the positive in channel 2 and 3 so i have the positives on channel 1 and 4 and the negatives on 2 and 3 with the 15 ran off of the 3-4 bridge. i didnt know how to run them any better

 

I'm trying to imagine that and failing miserably. My guess is that you are putting too much of a load on your amp.

I'd say ditch the 15 and get a 1ohm stable amp to run the 4 4000s to. If you can't get the bass you want with 4 subs then you're doing something wrong.

 

Yeeeah. Definitely toss the 15 and your amp will live longer.

Also, check the voltage at your amp. If it's dropping, it's causing the amp to draw excess current and that will produce excess heat.

 

i agree

where do you have the amp? if its in the trunk, try getting a fan and have air blow across it, or you can try putting it inside your car, like under your seat or something so that the A/C will keep it cool. i already started a thread about amp placement ( https://honda-tech.com/zerothread?id=454037 )

try looking at http://www.ikesound.com they have almost every brand of amp there at really competetive prices, and free shipping from what i hear, they are very reliable (see https://honda-tech.com/zerothread?id=457103

 

i thought i was crazy

 

Just so you know negative is not really negative on an amplifier. The + and - are just put there so you wire everything to play with the correct phase. Amplifiers put out an AC signal not DC. What does this mean? I will give an example with just a two channel to keep it simple. Imagine two cahnnels of an amplifier. L+ - and R+ - Inside the amplifier they switch one set of wires so the L+ - plays 180 deg out of phase from the R+ -. Sounds complicated but it really isn't. (Actually it is, just depends on the type of amplifier the manf. decided to build)

Sounds like you need to find those screws and wire things correctly.

Bonus question why do you get twice the power when you bridge an amplifier? Hint the answer is already given.

i reran the wiring and it came up better. i have i 12 each on channel 1 and 2 and 3 and 4 bridged with my 15. if i want a louder sound i just unhook the 15 and plug the other 2 12s into 3 and 4, at least till i get a new amp. now i just want to get a better alarm.
