    Help! Sub not acting right. Is it blown?

    Okay so I’ve had this Sundown Audio SA-10 v2 in my car for about 1-2 years. It’s been running at 1000 watts rms which is 250 over spec however everything I read up on said these subs could take way more than that. Anyways here in the past few days the sub had been cutting out making very little autible noise in the cab of my car. However it’s still moving and I’ve attached a video of what sound it makes. Thought Maybe tinsel slap or something of the sort? Don’t think it’s overpower and topping out because I’ve ran it exactly like this since I’ve had it. Could it be blown? I’m going to test impedance tomorrow and will update just looking for a quick response If anyone knows what this is. 4D4E29B8-1524-44E0-A390-13CCCD33BA21.MOV
  2. I recently installed 2 6x9 Alpine SPR-69 speakers in my 2012 F-150. I added an Alpine MRV-F300 amp to power all speakers. The headunit is a Kenwood DDX9703S. It sounds ok but something seems off with the distortion and can't get the clear bass I'm after. I'm wondering if having 2 way speakers in the front doors now with the factory tweeters still hooked up is causing issues with Ford's factory crossover? I've messed around with every setting on the amp and headunit and just can't seem to get it right. I was thinking about moving the SPR 2 way speakers to the rear doors and just installing component speakers up front. Any advice would be greatly appreciated!
  3. So I have a somewhat crappy aftermarket head unit (Boss 460BRGB) so that if my car is broken into and it is stolen it wont be too bad a hit. Anyways I recently installed a Hifonics Zeus ZXX-1000.4 amp for my 4 kenwood 6x9 speakers. The two door 6x9s are rated at 115w rms at 4 ohm and the rear 6x9s are rated at 45w rms at 4 ohm. The amp is able to deliver 125w at 4 ohm x4. I have the amp set at a low voltage until I am able to correctly set it. The amp is connected to the head unit through 2 sets of rca cables. For some reason when I turn the head unit past half way the speakers start smelling and burning up. There is no possible way the amp is delivering more that 45w rms at that low a volume. Before I added the amp the head unit by its self was able to hit 115db with the same speakers. The head unit can supposedly output 18w rms x4. With the amp added the speakers start smelling at 110db. The only possible way I can figure this is if the head unit is delivering serious distortion through the rca output which is amplified by the amp and causes the speakers to rapidly heat up. This is quite annoying problem because I am now getting less out of the system with the additional amp and would prefer not to destroy my 6x9s. My question is do head units put distortion/ clipping into the rca outputs? Should I upgrade the head unit or upgrade the speakers to ones with higher rms rating?
  4. I'm having an issue with my new car audio setup at high volumes. My head unit goes to 50, but after 35 or so the high and low pitch noises become distorted; the mid level pitches sound fine. I have pre-amp wiring going from my head unit to my amp that pushes 60 watts RMS x 4 at 4 ohms to my speakers that take 6-60 watts RMS (120 watts peak power). The only issue I can see in the distortion is the fact that I ran wiring from the amp back up to the head and spliced it into the original speaker wires. That, or I need an amp with a higher RMS. Any thoughts?
  5. Hi guys, i am new in the word of audio system for car, altought i find my way to do everything by myself because i like to understand how thing work together. i came across some problems this weekend after installing my front tweeters,speakers and rear speakers. I got also everything that i needed for the installation to easy up my work. Everything went smooth regarding the installation and next week iam suppose to get my aftermarket radio and its done. (not sur if ill put and amp) So my problem come from my tweeters, i notice when i crank my volume the sound coming from them feel like they are blown... but what i dont understant is that they are brand new, when the car is off and i play only the radio they sound and work really good. But when i start the car they start to distort, and i need to lower the volume so i dont ear the distortion. On top of that all my other speakers sound great nothing bad there. Its only my tweeters, something is wrong for sure and i didnt find my answer by looking on different forums. If anyone had a problem similar to mine, share it its might be my solution. thanks guys (sorry for the bad english)
  6. I recently installed an amp and two subs I was lucky enough to get from someone I found local here on the forums. This is my first amplifier install. The first problem I had was distortion in the left front speaker (not sure what kind of distortion, sounding janky at higher tones usually). I play a song with higher tones to hear it. It shouldn't be the settings messing it up because the other 5.25" is fine. I opened the door and inspected, and realized there was water inside that had gotten on the speaker and the wire. I replaced the speakers with identical new ones and sealed the vapor barrier (that's why water got inside). Problem still there. I ran wire directly to the speaker in the door (14 gauge) to the amplifier. Problem still present. I eliminated that channel (ch 1), and ran the fronts on 3+4, rears were on ch 2, nothing on ch 1. I did test different wire on ch 1 and different speaker, anything on that channel went distorted. I then started having distortion on ch 3. (left front again) That speaker worked fine on ch 4, and ch 3 was putting out the distortion. I switched my L and R on the amp from the RCA's and it was still on ch 3. I don't think RCA is a problem anyway because it isn't on the 6x9 on the same side (only one set of RCA's). I have yet to check if ch 1 is working (got better with time maybe?) Other than that I have some headlight dim on sub hits, and have had speakers (subs especially) cut out at very high volume with high bass, but only sometimes. Power delivery is a question, but my ground is good, and I've checked the power wire. Other than buying a bigger power wire I don't know what to check. If it was a power issue it would be all channels anyway wouldn't it? Other possibility... The power wire is going through the door jamb and it did get slightly pinched, but the wire inside the insulation doesn't seem affected at all. Since then I secured it away from all moving parts, no more pinching. Not sure about the gauge on the power wire since I'm new and can't eyeball it, but it is what I was given with the amp and subs, and this man definitely knows what he's talking about so I doubt he gave me something too small. He will come help me out when he has time, and I do appreciate that. I just want to get ideas of what I could troubleshoot in the mean time by myself, save him the time possibly!
