  1. i hear ya. i'll report back after trying a few things.
  2. oh, and just to clarify, the amp itself is emitting a buzzing noise as well as the speakers.
  3. i have the front battery ground wire bolted to bare metal on frame and rear distribution block wire bolted to bare metal on frame. both 1/0. rear frame ground is better than the front, so i'll redo the front. but there shouldn't be a problem there. both sub amp and 4 channel amp are on an smd ground block and that block is straight to frame. frame grounds are snug and painted over. i'll check the head unit ground tomorrow. the 4 channel RCAs are rockford.
  4. as the title states, my mids have been hissing and a buzzing noise is coming from my crescendo 4 channel. i just added a rear frame ground to the trunk thinking it was the chassis ground that was causing the problems.. the new ground is reading very low (.2) from rear battery to ground block. i think before it was like 16 ohm from rear battery to ground block. the speakers hiss, before (months ago) it was only the left side speakers, now it's all of them. the sound is louder when i apply the break, and before the new ground, i could easily hear engine noise. i'm not sure if the engine noise is still present. any speakers added will buzz/hiss. i'll post this now to see if anyone has anything i can try/check. i'll unplug the crescendo tomorrow and check if my rockford does the same thing. could it be the head unit, the fact that the speaker wires are running alongside the power wire through the cabin, the rca's? (rcas aren't ran with power wire.) again, there has been noise in the mids for months.
  5. i'm sure i was clipping it, probably due to my voltage being at 11 and the wolfram wanting 14 instead of my gains being ignorant. i smelled glue, but i heard different opinions on that glue smell. either way i won't have those problems anymore. thank you for your time. **edit** also, it's strange it'd go out while sitting instead of being in use.
  6. thank you. that's what i was looking for. so i'll learn how to recone a sub soon i suppose.
  7. i have a d2 sundown sa-12 v2 that, when pulled out of it's previous enclosure, was working well with no signs of anything being broken or damaged. it's been sitting for a few months now, and i got a second one with a new enclosure. disconnected, it reads ~26 ohm. i wired them together, and the reading at the amp was something like 26-30 ohm wired series/parallel. i can push the dust cap/cone down and it'll feel just like the new sa with no scratching but scratches with bass playing. i knew there was a problem at that point, and i'm wondering if anyone has any insight here. is it easily fixable by an amateur? is it worse than i think?
  8. thanks for the help. i guess i'm a crackhead, because my single set of fronts and rears doesn't please me, haha. i might just end up trying the crescendo 6x9 coaxials on the rear.
  9. i was trying not to be confusing, i'm sorry. i was just looking for some direction with my mids. i have 6x8s in the front doors, 6x9s in the rear. if i add two 6.5s to each front door for more output, should i remove the 6x8s? understand that i just don't understand how 4+ channels work yet. i'm not looking for any miracles, i just want to know if i could do anything with the 6x8s and 6x9s or if i should just phase them out.
  10. sorry if my formatting was weird. it isn't a comp setup, but it's my first build and i want to go over a lot of different options for the experience and to learn more about building a good system. i plan on adding more bass, and i want my mids to be louder. running the 6x8 off the deck was just an idea so i'd have output from them plus room on the amp to push the crescendos. the final impedance and load of multiple speakers is confusing the hell out of me.
  11. hello, i'm a bit confused on the wiring for mid/highs amps. i have a crescendo s4 4 channel: 2ohm: 220w x4 4ohm: 140w x4. i have two infinity kappa 6x8 2ohm 100 RMS and two 6x9 2ohm 110 RMS. does 220 RMS per channel give me enough space to run four 50 RMS or two 100 RMS midrange speakers at 2ohm x4? i'm planning on adding a pair of 6.5 to the rear and two pairs to the front in addition to the stock location speakers. since they're mixed, would it be smart to run the 6x8s off of the deck? no specific speakers in mind, but maybe some crescendo PWX 150 RMS and 80 RMS super tweeters. the front channels would each be pushing 300 RMS @ 2ohm with two PWX 4ohm in each door, right? a second amp for the speakers isn't out of the question.
