Subs kick in and out frequently

[pkwon121]

So I got a set of used subs and amp from my coworker a couple months ago, they sound great!

But lately when the volume is too high, the sub kicks out and there is practically no bass. I have a 15 Kia Forte and my original head unit that uses a line in converter. I know it's a bad setup but I didn't want to get a new stereo.

So I was wondering if it's the amp that's going bad? It runs really hot but I know that's typical for amps. Maybe it's the power wire cause the guy who installed it used 8 gauge wire. I told him to use 4 but he insisted they wouldn't draw that much power for 4 gauge.

If anyone knows relatively what the issue is, that would be great. I'm assuming it's not the sub because they sound really good when they are on.

By the way, I know the equipment I'm running is really old stuff but I'm happy with how they sound.

Yeah plan on sanding that black painted part down so it's all bare contact

I'm right there with you buddy. My sub is doing exactly the same thing when I get the volume on my radio up to 3/4. It just quits playing. Does Arron at low volumes, then hits that spot where it just goes away then back when I lower the volume.

Yeah, so my stereo maxes at like 42 or something and past 35 the bass gives out. But after about 40 minutes of driving it cuts out regardless of the volume level and kicks back on for like 5 minutes at a time

It's really frustrating

What does the terminals say on the back? Can't tell. Should say 2 or 4

Or it might say it in the back of the magnet sticker.

But just by looking at that sub, it look like it's wire up at 1 ohms or 2 ohms.. and you have two subs... so that amp is seeing a .05 or 1 ohm load...
