i have a kenwood 1800 watt amp and two pioneers 1000 watt each and a ported box . hits hard sounds good but they keep stoping totally and starting randomly. i know this is because of how i wired them but i tryed so many ways, is could it be that im using 18 gauge wire? should i try something different? any ideas would be appricated

 

or maybe your amp isn't powerful enough to power the subs after the stereo impact because when two 1000 watt subs hit at full power they completely drain your amps?

i'm not stereo expert, but it seems your subs are demanding more than your amp can handle.

 

the subs i bought from the kid worked fine with less powerful amp they are dual voice coil speakers btw

 

I have the same amp...
Mine dies every once and a while cause it got too hard
Mine eventually died and I sent it in and got the upgraded version...same wattage but a fan and such haha.
It works alot better now...

 

maybe it gets to hot ever think of that cuz i had a amp at one point with out fans and it would do the same

 

theres alot of variables when ur hooking up amp and subs, are the subs wired in series or parallel? what gauge wire is power/grd? wheres the grd at? in ur case i would have them wired series at the subs and u should have 4g wire with a good grd, it sounds like ur amp is overheating and thats why its clipping so bad so check all that and im sure one or all of those things will solve ur problem, well i think....

 

well i have a 15 also and when that is hooked up everything works fine so i know it has to be with the 12's and btw how much did u pay for this amp "ty Max"?

 

wuts the impedence on the coils of the sub? and how are u wiring the coils? if u wire them parallel then u cut the resistance in half and if it is to low for the amp to take stable, then its gunna make the amp overheat thats prob ur problem

ok im a nube so what is the impedence? i know they are 2 ohms each if that helps i found out how to wire them off a website im not sure what this method is called but on each sub i have the negative to the other negative terminial and then another wire from that terminial to the amp. and same way for the positive terminials

 

Could be that the amp is going into protection mode and/or overheating. It may not like the load, as your description sounds like it might be seeing 0.5 Ohms. If each voice coil is 2 Ohm and you wired them in parallel (that's what you described, which would create a 1 Ohm load), then you wired the subs in parallel at the amp, that would be 0.5 Ohm.

People will need to know the exact model of your amp & subs in order to determine if this is the issue or not. And yes, you should definitely use better than 18 guage speaker wire in this situation, but that's NOT the cause of your problem.

 

TS-W306C/DVC
12" Component Subwoofers with 1000 Watts Max. Power

400 Watts Nominal Power
4-Ohm Single Voice Coil (C) or Dual Voice Coil (DVC)
Recommended Enclosure Use: 0.85 ~ 1.75 Cubic Feet that is the subwoofer info i have two of those with a ported box (sounds awesome when they work) and this amp, kenwood 1800 watt kac-9152d, any help on telling me how to wire these would be amazing

 

Well the amp's specs state "1 Ohm stable", but it rated for the same 900w into a 2 Ohm load, it's output doesn't increase for 1 Ohm. If your subs are 4 Ohm DVC (sounds like it from your description), the VCs are wired parallel and so are the subs, that's a 1 Ohm load for the amp.

You can do a test to see if this is causing your problem. Wire each sub's voice coils in series for 8 Ohms, then parallel them for a 4 Ohm load on the amp. This is supposed to produce 500w, rather than the 900w (<3dB more SPL) it's supposed to do at 2 or 1 Ohm. If it no longer shuts down, then you know the amp can't handle the 1 Ohm load you gave it.

 

well my tc is in the shop right now cause of a accident but i will try that and anyone think it woulding do this if i bought a capacitator? i believe thats what its called

 

^ No, a power supply stiffining capacitor will not resolve your issue. They can be of value in certain installations, but won't help your situation at all.

 

ok well thanks for telling me that i was seriously going to buy one tomarrow thanks for saving me some money and im about to make sure these are wired to 1 ohms thanks for everyones help!

 

If you have the stock headunit my sub will do the same thing. But its due to some quirk in the system. Anything above 40 and the sub will eventually cut out. but 40 and below, never have an issue.

I really need to get rid of the stock HU....

 

if you have it hooked to the stock radio it might the high low converter.

 

u think? never thought it could be anything like that, it cant because i had plenty of systems before this one that worked fine everything works fine when i just hook up my 1 mtx 15

 

today i went out and bought 12 gauge wire. is that big enough? im getting my car back from the shop soon should be before friday and going to put them back in and see what happens i might buy a capaitator too.....sorry about the spelling
