  1. I recently upgraded my audio system - added 4 channel amp for door speakers, subamp for subwoofer. Work is complete. Now i have to set the gains on the amp. I'm trying to see if anyone might be willing to let me use their dd-1. Thanks,
  2. Battery in front with engine? I wouldn't use the seat bolt. Found that our the hard way myself. Lol. What happened in your case when you used the seat bolt as ground? and what kind of difference did it make when you changed the grounding point to something else. It would cut out and my subwoofer would try to play. But would only play on very low volume levels. Now I can listen it it at my normal listening volume without it cutting out. i don't have the problem of amp cutting out. Its just that the woofer sound is very feeble
  3. I have a eonon gm5151 for mazda 3. Now using the stock head unit. RCA are being run straight to sub amp. I live in china town. 29th and king drive. THanks.
  4. i went the easy route and bought the sub & box combo from rock ford fosgate internally wired to create 1 ohm (DVC) http://www.rockfordfosgate.com/products/details/p3-1x12

  6. Car: Mazda 3, 2009 Speaker wire to sub: 12 gauge Power/ground wire: OFC from http://www.amazon.com/gp/product/B001U636NQ?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00 Grounding: Rear seat bolts. Please ask if you need more info. I'm a total nooob in this.
  7. I have two amps in my car. one powers the door speakers (400 amp rms - rockford fosgate amp) and other power 12in subwoofer (750 amp rms - rockford fosgate amp). Both the amp is getting power through 4 gauge wire and grounded with 4 gauge wire. The door speakers work great, but the subwoofer hardly moves. I tried two different head units (stock & after market) and yet the sub hardly moves. The after market HU came with dedicated subwoofer output, while with the stock HU, i had to splice into front speakers wires to get signal for subwoofer. In both cases, the sub was weak with gain all the way high.The sub is getting signal, but its not moving the way a 12in should move. It only starts to move properly when i increase the bass boost & punch eq (i know this is not good). I went through some trouble shooting - making sure ground is securely attached, power etc etc. Yet, still can't figure out what is happening. I took it to a stereo shop and he agreed to diagnose for $65. But i've always had issues taking my car to shops and i'm wary of taking the car to the shop. What do you guys think is happening? Is there any one in chicago who might be able to take a look and help me out !!! Thanks,
  8. i didnt make the measurement at the head unit out of fear of damaging the rca. I did the measurement from the RCA cables coming off from the head unit.
  9. This is an after market HU. It has stock RCA outputs. The amp is rocford fosgate and it comes with punch eq and other bass boost knobs. I don't want to use them as i've read some where they are bad. At the moment, with gain all the way up, the amp hardly moves the sub.
  10. Nope, since you had a speaker wire unplugged while you were testing your amp wasn't actually pushing any watts out so there was very little current flowing through the power wires. You could have had it wired up on 16 gauge wire and it wouldn't have made a difference. Now that being said, doing your big 3 will be beneficial once you get everything figured out. So here is what I would test next. Unplug your RCAs at your amp and test the voltage your HU is putting into them using the same process you used before. I'm curious what your HU is putting out for voltage. Let us know what the results are. Sorry for the delay in getting back. I carried out the measurement using the DMM at ac voltage setting by unplugging RCA going into sub amp. The reading i received was just around .2V. This was with the sub setting turned all the way high in the head unit. Does this explain the problem i'm facing?

  12. do u guys think this has anything to do with not having the big 3 upgrade. like the amplifier not getting enough juice from battery. i'm using 4 gauge for both power and ground
