_paralyzed_ Posted August 13, 2014 Report Share Posted August 13, 2014 Both amps are mounted under rear seat. I was told it's not getting enough power. I need to move the amp closer to the head unit and shorten the rca's??? I'm not sure how moving the amps and shorter rca's are going to help you. If you need more power, you probably need to have 0 gauge power wire. And i'm sure a better battery would help also. Not for under 1000 watts, 4 gauge is plenty and any battery can handle that. Did you set your gains properly? Also remember those pioneer gm-d series amps are designed, as soon as they detect distortion, they will reduce the output to almost nothing. Try turning down the gains on your 8604. I have the 8604 and it performs great, as long as gains are set correctly. The gain is at normal. (4v which the head unit has 4v pre outs. You cannot guarantee the head unit is putting out clean power all the way to 4v. Turn your gain down a little at a time and see if the problem goes away. The "normal" setting is just a mark, you need an o-scope or a dd-1 to set gain properly. Link to comment Share on other sites More sharing options...

thefourth Posted August 13, 2014 Report Share Posted August 13, 2014 What are your crossover points set at? Thanks alaskanzx5 I might just do thatI can recone a sub myself. About a year ago I took 2 12" power acoustic mofos and made one sub. I took the magnet and the motor off of one and j b welded it to the other motor and magnet. I had to wind my own voice coil so it would work. After I was done hooked up to 2 boss 5000w amps. And shattered my back and all my side windows came to this thread to recommend soundqubed and ct sounds. OP goes with soundstream. oh lawd.

alaskanzx5 Posted August 13, 2014 Report Share Posted August 13, 2014 Hook a dmm up to the pos and neg on the mid/high amp. Replicate the issue and measure voltage drop. That will tell you if that is the problem. If not Turn the gain down and see if that helps. If it does that was your issue If not Then check all the wiring in the whole system. Make sure its your kids and highs and not just the highs or just the mids. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.

I see about 1k depending on how the 4 channel is set up. I do see mentioned that he has double grounds, not sure what he means by that.

hispls Posted August 13, 2014 Report Share Posted August 13, 2014 That's why as soon as it detects any clipping-distortion, it automatically reduces the output. Sounds like a protection feature to me. Still I'd wager that OP is trying to push that amp beyond it's limits. OP. Disconnect the remote turn on lead from the sub amp (tape up the loose wire while you test) and see if you can replicate the problem. Link to comment Share on other sites More sharing options...

We don't know what battery he is running. To say any battery can handle that, is just not true. We do need to know what these double grounds are about, and what they are hooked to. Size of stock alt. Battery specs. truthsayer Link to comment Share on other sites More sharing options...
