Hey guys I am having a issue with my amp and trying to figure out if it's my amp or the way it is hooked up. As of right now I have my power wire mounted on the top 12mm bolt on the positive side and my ground wire attached to the bolt that holds the rear lower seat in place. I have my remote wire hooked to a add a fuse in the fuse panel under the dash that turns on with the acc. The rcas are connected a line converter that is connected to the right side front speaker.

My issue is I have adjusted my amp for better sound and for it to hit harder and cleaner. When I get it close to max on my radio and it is slamming super hard my amp cuts in and out. I have and adjustable knob up front so I can turn the amp down when I need to and when I turn it down it still cuts in and out. I noticed that when it's slamming hard the amp shuts down totally. The light on my adjuster shuts off and so does the amp. I am wondering if it is pulling to much power from the spot I have it connected to on the battery or if my ground isn't that good.

Just wanted some advice to see what I should check. My setup is a memphis audio 500w amp with a memphis 10" 500w sub in a ported box. I love this setup because it sounds like I have 2 12" subs and really don't want to go away from this brand. I have had this setup for about 3yrs now but not in this car. In my previous car (kia soul) it worked flawless and now I have this issue. Just seems strange

I'm not a huge audio guy so any help would be awesome!

I am having issues as well. At like 70% volume my sub is kicking, any more than that its like the sub is almost mute.... I thought about contacting PAC audio (that's the splitter I used) and see if it was the splitter. Since you said this I think its more the car..

Exactly what mine does. If i push it to hard it starts to do that big time. I have been debating to get a capacitor to see if that would help or not. I have never needed one with my other cars unless I am pushing over 1,000 watts.

I think it's the car also or where we are getting the power from on the positive block on the battery.

Right from the battery. I think when Kia made the stereo system they hired a 5th grader. I think its due to weak stock stereo amps. If they are weak then I think the more you raise the volume the less bass signal they can produce, so the splitter isn't getting any bass signals to pass onto the sub.

If that were true then I should still be getting power to mine. My power shuts down completly

It's mounted to the back seat. I am thinking of moving it to under the passenger seat

I have noticed that with my F5 and my wife's soul+ that sometimes I will get in, turn on the car, and nothing will come out of the sub. It's like no signal is going to my amp.

Regardless, I have found a solution for when this happens. All I did was adjust my fade in any direction and BOOM! the bass is back.

Idk why both of my Kias do this but that's how you fix it if anyone else has experienced this.

I have tried fading it to the front where I have the line converter setup and still nothing. I just moved my amp power wire to the 10mm bolt that I saw max (knee) say that he puts his stuff on so I will see how it works. I will probably go out later tonight and see how it works. Right now its 105* out lol

I have the same issue with my amp too, I'll have absolutely no bass and then just one simple touch fade up or down and everything is back to normal.

I connected the line converter behind the radio using both right and left rear speaker outputs. Disconnected all speakers at the speaker and turned volume to 100% and adjusted the output on the RCAs to 2.5-3 volts to prevent the amp from going into protection mode from to high of voltage through the low impedance inputs.

I just find it really strange I have had this setup in the car since I bought it in Oct and has been slamming g hard since. It's just this month started to do this. I think my sub might be going out. May have to switch to a alpine 2000w sub lol

Our swimming pools are like 96F-98F right now... so dumb lol
I live in a condo complex and the pool is heated all year to 88*. Really sucks lol

Well I have tracked it down to my sub burning the coil out. I can hear it cracking when at low volume and the inside of the box smells. So I am sure it's causing my amp to go into protection mode. I am going to go to my car audio shop this morning and look into a whole new setup. Going to see what they offer for a good price that slams hard lol

I have a 300 watt Alpine amp connected to a 12" mtx sub. Slams perfect without any real rattle. Saved me a ton on dynamat

Nice! I have been really happy with my setup and get a lot of compliments on it and told it sounds like 2 12s in the trunk. I am going to see what this shop will charge for a more powerful amp and a better sub that can handle some good power and a new custom ported box for the sub. I would put the sub in the floor like some have but I still use the trunk!

Well went to the audio shop here and dude was really cool with me and helped me out. It is the sub that took a crap on me. So I walked out with a Phonix Gold Ti edition 600w rms 1400 peak and he said it would match my amp perfectly. I was looking at the Alpine SWR-10D4 that handles a peak of 3000w but he said I would possibly burn my amp up from it trying to push it because it is a 1000w rms sub and he didn't want to see me back in a week or 2 with a blown amp.

I haven't hooked it up yet so I am not sure how it sounds but the floor model wow! It slammed harder than mine in a sealed box! So I can't wait to install it and see what it does!

What kind of amp do you have? I have never heard of a phonix sub. Definitely glad to hear you were able to pin point the problem. It's just not the same when the bass goes out.
