  1. I do have stock speakers I can try hooking up, but yes the headunit does not matter. When I test another speaker I'll come back here
  2. I got KnuKonceptz Kolossus Flex RCAs and they are routed on the opposite side of power wires (I learned this when I did my first sound system haha) The Big 3 is 0 gauge Soundqubed 0gauge, both amps have 4 gauge power wire bot hOFC, and 4 gauge ground wires connected to the 2+2 fused blocked with a 0gauge wire connected to the car for ground. Volume level and gain level does not effect the hiss no matter what. Once the amp has power and is on, and a speaker is connected, the hiss is there. The hiss comes from all 4 corners, and its a lot louder from the rear coaxials compared to the front components (which i notice the hiss from the midrange and tweeter) Honestly guys, I believe its the amp itself causing it. Some internal parts somewhere like a noise filter or something is doing it. So I think its normal for this amp and I have to deal with it until I get a different type of amp.
  3. Correct. Volume at 0, RCAs disconnected. The hiss is constant, same volume, never changes. And when I play music and turn up volume, it stays the same volume in the background. The louder the music goes, the less you hear the hiss. Only at Mid to Low to No Volume you notice it
  4. Yeah, forgot to say that. The gain does NOT effect the hiss. As long as the amp is turned on, and a speaker is connected, the hiss is there.
  5. Well, I don't know if this is good or bad news. But I changed the ground behind the HU and the constant static-like hiss is still there. It must be produced from something inside the amp. I'm assuming this is normal and until I get a new amp, I'll have to live with it.
  6. Oh wow ok, I guess that makes sense. I'll change it anyways and test it out. Thanks for that info!
  7. Nah the hiss doesn't change with HU volume. And it's all factory ground behind there, I did solder the wiring harness connected behind the headunit.

    Quick Question

    The Amps are mounted on a 3/4" mdf piece screwed to the box, I guess on the back? They are in between my rear seats and box. I'll keep a close eye on their temps, I havent been playing my system too much because I took the sub out. The amps are more in shade than anything else

    Quick Question

    I like the sound of that haha. Ever since I started throwing subs in my car I've always been worried about thieves. But now with the tint, unless you got really good lighting, you can't see inside the rear. And thank you! Recently moved from expensive ol' California and I am happy to be here. Only negative is the heat but I can deal with it.
  10. Got the amp hooked up to Hertz Energy 3 Way in front and TX65 coaxials in rear. From the very first day I hooked up this amp, I've always had this constant static-like hiss sound coming from speakers (more noticeable from TX65 coaxials). I've also had the amp replaced brand new from Skar so this is my second one and same exact scenario. I have been told this is normal and not. The sound is constant and happens with the amp being powered on and speakers wired up in any channel of the amp. My Ground wires for both Skar RP amps I have, are connected to a fused 2-2 distribution block with 1 0g wire connected to the body of car, does this matter? I do not notice the hiss from the sub at all RCAs do NOT change it. Headunit volume does NOT change it. Car ON or OFF does NOT change it. My guess was Speaker Sensitivity with my coaxials having 89db(most noticeable) and my Hertz components 91db(less noticeable from Tweeter and Midrange) This is my first time ever having a 4-channel amp in my car sound system.(I've had the amp installed for a few months now) So I am just curious to why this happens, is it normal, what would I have to change to get rid of it (speakers or amp)? Curious if others have this too. The constant hiss is most annoying when your surroundings are quiet with no music, and with music at lower volumes you slightly notice the hiss in the background of the music. Also noticed my computer speakers (Mackie CR3s) have a similar hiss sound, so I am assuming it's normal which is why I haven't been too concerned. Thanks

    Quick Question

    So I got a Scion tC with a Rockford T2 15" black cone in the hatch. Recently moved to Arizona and I am wondering how worried I should be about the sunlight damaging the sub? The way I made my box, has the sub facing up at the window and port back towards rear. Windows are tinted 5%, the box is painted black. Let's say my car is parked outside 5+ days a week for over 6+ hours cause of work and when I am home, the car will be in the garage. I do have an extra sun shade that I cover the rear hatch to help the amps and sub. Also I bought ArmorAll Protectant to clean the sub. Should I always use the sun shade whenever I am out? How often should I use ArmorAll or is that not a good product to use? I took the sub out for now thinking of getting a cheaper sub to replace until I build a new box with the sub also facing the rear like the port, should I stay with this? Thanks guys
  12. I got a feeling it's too outdated. Someone near me is now in TX. Thanks for the info, yeah I like my Skar, just unsure about the Hifonics for the same price
  13. 1500 is good for the sub but I feel it can easily handle a lot more. Yeah I'll have to see what batteries I can fit and just pick one. And yeah I do wanna tune my setup properly before I get something, all the DD-1s are sold out so I'm trying to find someone nearby that has one I had my friend tune my amp with a DD-1 but we just set it to whatever volume level we felt like because he said we couldn't find the max nondistorted volume level without a speaker amp (not my sub amp). Which is wrong I believe so that's dumb..
  14. Ok I'll check out some group 31s. Any recommendations on a better amp. I was thinking close to 2500rms preferred. Also that clip light on helps me tune the amp, I still don't know what volume for my CDA-105. Waiting to find someone with a SMD DD-1. If anyone near Vista, San Marcos, Carlsbad, CA area with a DD-1 hit me up please?
  15. Sup SMD Forums, I've been thinking a lot about my current sound system and what to do next. Money is tight so trying to make the right choices here. So in my '15 tC I got a Rockford T2D215 hooked up to a Skar RP-1500.1d, with stock battery 530cca, and stock 100amp alternator with Big 3. The way my amp is tuned I still don't know 100% if I'm getting full potential because I don't know my headunit max clean volume level. Still sounds really good though, no overheating, burnt smells, and no distortion. So I wanna get a bigger amp for this one sub, currently looking at RP-2000.1 and BRX-2400.1 I wanna know what I need to do for electrical to support it. I've always preferred having a single battery so was wondering if I can manage that. A high output alternator costs some money but can I manage with my stock one Still? If I stay with my stock alt, is there a single battery that'll work or is a secondary required? Picking a secondary battery has been difficult mainly because I don't know how much more amps I need, and also I have no idea how I'll mount it since my box takes up 90% of space. If I can't get answers then just mention what numbers I need to look for and what math I need to do. I built my own box so I can figure some things out but I don't remember everything now and I'm gonna have to relearn when I make a new box lol. Purpose of this post is for advice, discussion, and maybe help others that are similar to me. Thanks in advance
