More SA8V2 problems :)

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..

IIRC it needs to be in the negatives, try turning it to say -10 and see if the sub volume increases. I know just reading the manual it goes from +6 to -24 and I swear this was the deck that needed to be set that way. And 20Htz no workie.....

20hz?!?!

I didn't see that was a guess :| I had nothing to turn it with so ill find out when I get home I guess :\ anyway here is the picture of the speaker wire they used for the sub, just to give you a general idea of how I feel about this whole situation.View attachment 26537075

Set the LPF to 80Hz and see if the sub plays louder.

All pioneers I've used are -24 to +6, and +6 is of course the loudest. Going from 0 to -10 will make the output much lower.

Tiny wire, but it won't cause this particular issue.

If you get a chance on break run out and snap a pic of the settings on the amp. I would imagine that is part of the issue along with head unit settings.

Yeah, but the 80prs goes from +6 to -24. Again, I believe its different but never used that deck.

Nah the zero setting is where he needs to be my 80prs did turn it down a lot when I ran the auto eq though. And I'm betting they prolly cranked the subsonic filter way up and cut all the bass off the system.

Check the subsonic filter on the amp it should be set to around 27-28hz in you case and the low pass around 80hz gain with that deck should only need to go up roughly a quarter ways maybe a bit more.

Here is another example of whats going on, and again points me to RCA voltage.. Playing one song, (cant remember the name) lots of bass, have the gain knob at ~2% (Because the gain on the amp is still maxed after that tard master fiddled with it) next song comes on, I remember this one, its "look like you" by lil wyte, anyone who knows the song knows it has good bass. But I cant get any sub response, only midbass, turned the bass knob all the way up, even turned the deck volume wayyy up, and then I could hear a little bass, and I mean LITTLE, but the highs are derpy loud by this point.. Then next song comes on and its clipping its *** off :\ and I turn the volume wayyy down and drop the gain knob back to 1/2%. so now im stuck with heavy bass and quiet vocals, and then the sub gets stinky. and I /frustrate to the max, and turn the radio off

Here are the amp settings, sorry for the horrible picture out of 6 it was the best //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Turn subsonic filter down to 0 and then turn it back up to 25(ish). Turn your LPF up all the way then turn it down to around 70-80(ish).

Turn your bassboost down to 0

Turn your gain down to 0 and then turn it up a 1/4 turn

do that and then try music again and see how that turns out.

20hz lpf. will cause no output lol

shop will do this to make you think other stuff is junk. when ur tired of dealing with what u brought in they will sell you there equipment, seen it happen alot....

So it's also possible that they wired the sub wrong on purpose too (If it's even the case). Got a dmm?

Ill let you know man, if I get close to 0 output from "basey" songs, what would be the next step?

I would swap to an MP3 for signal to your amp. If that does not fix it, then pull the sub again and check the wiring.

buddy had a btl 18 that came with the trail blazer he bought, took it to a shop which i told him not to... they said it was blown when i checked it on a dmm from the start and they took it and tried to sell him some alphasonics... i told him to go get it back well it was long gone by them. what a dumb ass move by a dumbass kid and dumbass shop. he couldnt wait until the weekend until i was able to do his install...
