subs doing very weird things

[brettley 10+ year member]

I have a setup-in-progress currently.

2 12 inch L7s

2 kenwood KAC-9104D amps

2 Power Akoustic capacitors (3f each i think)

Pioneer AVH-P3300BT head unit

KNUKonceptz 4 gauge ofc wire from the battery to the fuse at the firewall

rockford wire from the fuse back to the trunk

rockford distributors and everything

the problem happens randomly, I will be driving along (started today) and all of a sudden my bass will stop, and my capacitors will start beeping from low voltage. I checked my battery connection, I checked the fuse connection, I checked the ground connection, I checked the distributors connections, the capacitor connections and the amp connections and did not find a single thing loose.

I have had THIS setup running over winter, and into the spring with no problem, this just started today. I have just bought my big 3 wires (0 gauge OFC wire from KNUKonceptz) but have not installed them.

what do you guys think is the problem? this happens randomly, and only cuts the subs out for about 5-10 seconds. then music starts playing again. also, sometimes the capacitors will start beeping.

the capacitors are on there way out the door once i start building the battery bank, so don't mention those unless you think they really are a problem.

thanks guys!

BTW this is what the trunk looks like:

voltage dropping too low? you have stock electrical...

and the subs arent doing wierd things, your doing wierd things to the subs

If you keep doing what your doing you are going to fry your alternator, battery, amp and subs.

You have a lot of work to do guy

Ive seen the in one best buy.. I have 4 within 20 minutes and the all have diffrent brands. One has kicker one has fosgate, mtx and alpine

I NEVER will buy from best buy. Will the big 3 fix most of the problems? why has this never been a problem before? I built the box myself, thanks for the compliment on the box!

Electrical system might be getting weak. Those caps will mess some stuff up

 

[brettley 10+ year member]

once the big 3 is in, I think I can remove the caps, or atleast rely on them less. Will it help alot?

caps like that fail. i'd start by removing them and upgrading the big 3.

remove caps and buy a stinger volt meter and install on dash and see what ur voltage is doing. I bet you are dropping to low 12's high 11's which would explain the issue you are having. Oh did I mention REMOVE the CAPS they might look pretty but to anyone that knows audio you look like a noob plus they prob are hurting ur voltage more then helping.

What you need to do is this.

Upgrade all power wire. BIG 3, Get a H/O alt. and get a nice deep cycle battery under the hood and a few in the back.

 

[brettley 10+ year member]

I actually plan on this: I have the big 3 hardware, just need to get a way to lift my car to put the alt wire in (alt accessed from under car). I will be starting to replace my capacitors with stinger power cell batteries (the smaller ones for trunks). And lastly, a RED top battery or similar will be going under the hood. First the big 3. then the engine battery, then lastly will come the trunk batteries. does that sound like a good plan?

The reason my big 3 isnt already done, is i jut picked up a light duty table vise this morning to clamp down the terminals. I also have not yet figured out how it will connect to the power terminal since i do have factory battery terminals (uh oh).

why is that a bad thing? you pay over 1000 dollars for junk subs, junk amps and end up gettin bullshitted into buying capacitors since mostof those people dont know shitt and the best buy guys know even less. take the ****** capacitors off, they shouldnt be used...ever. they are only making the problem worse. the only place they are applicable is a system with no electrical issues and in that case they wont help anything.
