Rear Speakers cracking after i installed capacitor

[FurbiesAndBeans 10+ year member]

So before i was running my system pretty decently without a capacitor, but people kept telling me i should get one because it made the bass hit harder... Anyways, once i installed the capacitors, the bass got louder, but also the back speaker's cone started to crack. I didn't change any settings at all. I unplugged the bass amp to see if it was giving them too much power, but they sounded fine. So i turned down the bass amp, but it still kept making the speakers crack (now they are even quieter than before the capacitor).

Any ideas on how to fix this?

...uninstall the capacitor? It's a nearly useless upgrade and if it's hurting your system more than benefiting, why keep it? Another idea is to just ditch the rear fill.

well i have the capacitor at the moment because im planning on selling my car.

when i bought the car, it was already wired with 8 gauge. I just made it longer to go in my trunk and installed crossover, 3 amps, subs, and speakers in the back. I had already blown a fuse without the capacitor from turning it to loud. So with the capacitor i can turn it louder without blowing my fuse.

Also i've tried opening up the backseat so the air can flow more freely into my car, but no success. Only thing that's worked is opening my trunk.

Edit: this is my setup

Subs: two MTX 8512 in a ported box

Sub amp: EVD 2200 set at 4 ohms (i know it's suppose to be at 1)

Rear Speakers: Two 6x9 JBLs 545s

Highs amp: Soundstream (i think its around 60W x 2 rms or something)

Mids amp: Legacy (forgot the model)

Yes, i know i could do better but all that stuff was free except the bass stage.

Ditch the 8 gauge and go to 4. Then ditch the cap, that should make up for the lost voltage and blown fuses. Someone correct me if I'm wrong. And again, ditch the rear speakers or turn the volume down on them. Do a search and find out why.

ugh... didnt read my post. im selling the car soon, so im not gonna spend more money on it. and i cant ditch the rear speakers... i dont have front speakers, lol

Oh wow, my bad lol, reading>me. It's late. I still say ditch the cap and put in a new fuse, just before you let the car go turn down the gains so the new buyer doesn't go to high on the volume knob and blow the fuse and come bìtchng to you. Hopefully someone with much more knowledge than me will chime in.

Then take out the capacitor and put a bigger fuse in there, what size fuse was blowing? You are running too many amps to have just 8 gauge wire, I think you already know that.

You're pretty right on //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif//content.invisioncic.com/y282845/emoticons/thumbsup.gif.3287b36ca96645a13a43aff531f37f02.gif

Psh, im not give the new buyer anything but the head unit and the old rear speakers. Currently im running the amp at 4 ohms, which means about 360w rms. The fuse is a 30 amp fuse.

Yea i know 8 gauge is too small, but it was a convenience for me =)

My next car im thinking of either going 4 gauge or bigger with the same set up, plus front speakers.

Wouldn't hurt to go 1/0 gauge just in case.

Cap = FAiL

You can run a bigger fuse on the 8ga without any problems. Try a 60A.
