More SA8V2 problems :)

Also, could we get a picture of the amplifier settings?


Thanks! Been a while since we talked last, text some time when you get around to it.

I'll try to get some pictures, im at work now so it might take a bit. I hope to have them up today. Rabbit you know what your doing, you have always been an awesome help, even with that box for the SA12s that had gone through so many hands you still helped me. Anyway, I brought my car to the shop last night, and they looked over everything for an hour and a half and could find no explanation why music wouldn't give hardly any sub output if the gain wasn't maxed. (The HU was at max clean volume), play a test tone, and it worked fine, play music.. nothing. But the guy wouldn't tell me what db the test tone was.. (like if it was a -5 or 0db tone) and when I asked he told me it didn't matter.. GEE BILL, it does matter.

LOL I remember that.

It could be a few issues, I'm just trying to think of the best way to explain how to narrow it down.

If you want, video always works great too //content.invisioncic.com/y282845/emoticons/sneaky.gif.7189749b3a3f769e8815b47e8ae87f88.gif

I have been posting a lot about my new install having no bass, I took it back to the shop that installed it and they are now telling me its the box that's not putting anything out. The box was made by DC-Creations and seems fancy enough, made of solid birch and cool stuff. But the guys at the shop said it was tuned to 27hz and that was why my sub had no output, even with high excursion... Anyone have an idea here? id love to hear it

I'm sorry but WAHT???? Boxes don't put anything out....that shops retarded.

Isn't that 80PRS the deck that has the weird setting for sub output, something like factory its set to 0 but to get any output you need to go to negative something?

haha, ill take a couple man //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif But again it will be after work //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif For reference, before I got this system, I bought an SA8v2 and a JL500.1 for my brother for his birthday. We made a sealed box out of scrap wood and a **** load of caulking, put it in his jeep, and it sounds fantastic. I get double the power, bigger ported box, and I can't get close to what he does. I'm not trying to complain it just broke my spirit (in a non **** sort of way) Anyway! I am sad enough to wall my trunk with a 15 and a 2500, but I dont have any money after dropping nearly $2k on all of this + the install.... I miss my bass, even the 12s in that derp box slammed. I remember my brother saying anytime he was near me in traffic he thought he had a woofer in his jeep //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Oh also!! even with the test tones and even after that guy maxed the gain, the saz1000d was putting out ~720W RMS, so I KNOW somethings wrong. 22V @1ohm.. I remember my 1500 doing 52V@1ohm.. That was a fun day //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

With the gain maxed, bad anyways, but only getting that amount of power sounds like either:

-a voltage issue from the deck

-amp issue

-or the sub settings wrong on the deck to me.

Maxing the gain isnt really doing what you are thinking its doing. The gain knob is to match the input voltage from the deck via the RCA's to the amplifier. Have you tried a different CD by chance? Have access to another deck? I would personally try another deck out first, even if its a crappy sony or something like that

this.. check sub settings on deck. back when i was noob i was like da fvck is this so quiet. then i forgot everything reset when i took terms off the batt to install amp //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif

also, what is your remote power wire like? Ive seen people use skimpy wire for that and man, did it do some weird shit

Actually the easiest way to test the RCA or RCA output of the head unit is to snag an MP3 player or phone. Use a headphone to RCA converter and just plug it straight into the amp.

i was actually going to mention that, lol...i have used an iPod before...

I have an Ipod at the shop for just that reason actually haha.

We have a client come by and have a complaint. I will pull the RCAs plug in the Ipod and see if the amp is doing what it needs to(eliminating the source unit from the problem at first). If it is, then I move on to the next of possible issues.

I think/hope its a voltage issue from the deck... But the mid/high amp is loud as balls.. The sub settings on the HU are 0db, 80hz hpf. hpf on the amp is ~ the same, with LPF being around 20Hz if I remember correctly..

Did you just say you have the LPF set at 20hz for the subwoofer?

That's an awesome idea I have a couple at home ill try, as for the remote wire i'm not sure I wasn't paying attention last time I looked. But when you see what they used for sub wiring, you'll start to question everything. Im actually going outside to take a pic, brb rage..

I didnt actually see that was a guess, ill look

20hz?!?!
