A friend of mine has a 2007 Lexus IS250 that keeps killing amps. It has gone through 4 now. We have never had issues an any other cars until he got this one. We have tried upgrading wiring, checked grounds, and made sure the subs weren't running at some crazy ohm load. We cannot figure out what is wrong. Can anyone give us any pointers?
Current set-up
2 kicker CVR 12" 4ohm DVC - coils wired in series up to 8ohm and subs wired in parallel back to 4ohm.
Skar audio 4 guage wiring
Line output wired from factory amp to subwoofer amp
It is currently on its now second toasted skar audio 1200.1D

I'm in no way anywhere close to professional. I've never built anything custom (boxes, kick panels, etc) but this is disgusting. I do all my friends installs (mostly cause i don't have a car or the funds to do my own) and i would never ever do anything like this. What would make them think it's okay to glue tweeters to the cone of the midrange???

depending on how much power your system is, i would suggest upgrading to audio batteries
I think its that sony 600w, his stock should be fine.
But it never hurts to upgrade electrical op.
it's not the sony amp. just used it as an example... i'm planning on running two amps. a 1600W and a 700W crunch
wasnt sure if that pic was the actual setup, or if it was used just as an example
it was just an example

Yeah prolly posting in the wrong section and 95% of the time the people using caps don't need them. Very rarely do they have an actual use. Don't worry about hooking it up, sell it and do the big 3.
i'm getting a diesel which will have 2 batteries and i plan on doing the big 3, you think i'll be fine with that?

Because you are probably posting in the wrong section.
it's general... i should be able to post anything here

i know how to wire a capacitor normally but i'm looking into one that has built in distribution blocks so can i wire it like this?? ps. why do all my posts keep getting delted?

Umm as stated above that is not a 8ohm sub that is just the resistance it is wired to. So you could wire it in parallel + to + - to - and get a 2 ohm load to the amp if it has d4 coils. For more power from the amp you would not need as big an amp that way.
But yes you can have more ohms then the amp is stable for so if the amp is 2ohm stable you can run anything 2 ohms or more to the amp like 2,3,4, exe. but you get less power the higher resistance. But you can not run less then 2ohms like 1 ohm or .5 of the 2ohm stable amp.
Thanks again! you just gave me the answers to things i've been wondering for awhile now

X2 that works great it is wired in series.
Edit: That might be peak but ya it should run off 400 watts @ 8 ohms
Thank you!
now one more question...
i always do all my window shopping on sonicelectronix and when looking at amps i always see things like RMS bridged @ 4ohms. i never see anything talking about 8ohms. so an 8ohm sub will work on a 4ohm stable amp correct?
-
It's a completely valid way of wiring. I would assume by the name that it is a dual voice coil 4 ohm sub. That means it's wired like this:
ok so on the bottom of the sub it says 800W, so that would mean RMS it would run 400W at 8ohms?

so i pulled this subwoofer out of a limo my dad is driving. the wires were cut and it was being unused so my dad said just take it. it was hooked up to a normal stereo amp with no low pass filter and i'm pretty sure the sub is blown. i don't have an amp to test it right now but when i pulled the subwoofer out of the box i was kind of suprised. now i'm no audio pro but i would say i know a decent amount. (i did hook up my friends whole system in his truck even though his subs are over powered right now due to the amp he had) my question is. does this wiring set-up even work? i've never seen a sub wired like this before, please give me as much info as possible. include info about what it does to ohm load and yada yada yada.
sub is an AudioTech AT - 1044

wish i had a system to slap. my system's bone stock :/

There is an LOC between the factory amp and the subwoofer amp that is converting the signal
