Searched everywhere but it seems like no one has had this problem, I literally signed up just to see if anyone can help..Im no noob to car audio but i dont know everything. I pretty much upgraded from one amp to two amps. Honestly it could be alot to read.......
My Current Setup:
4 gauge power wires(150 fuse close to battery)
Distro block for ground
Fused Distro block for power(60A fuse)
(1)4 gauge in (2) 4 gauge out to amps
Kenwood KAC-9013D - Sub Amp
4 channel Soundstream EGA1000.4X Edge Series - Speaker amp
Alpine iDA-x100 - Headunit
Audiobahn 4 ch RCA - Speaker rcas
Uknown brand RCA - Sub RCAS
Front - 6.5 Boston acoustics component speakers(65w rms)
Rear - 6.5 Infinity reference 2 way(65w rms I believe)
Sub - 15 Inch Eclipse titanium(750w Rms,4 Ohm Sub)
Specs on Amps: I have a 4 ohm sub so im only puttin out specs with 4 ohm ratings:
Alpine Mrp-M500 : 300w Rms,500w MAX
Kenwood KAC-9103D : 500w Rms, 1800w MAX
Soundstream EGA1000.4X Edge Series : 2000w MAX
125 watts x 4 chan. RMS @ 4 ohms
250 watts x 4 chan. RMS @ 2 ohms
Bridged: 500 watts x 2 chan. RMS @ 4 ohms
To make it short I have 2 amps one for sub and one for speakers..Speakers get good power from amp and sounds amazing...Sub amp is putting weak *** power out. I went through two SUB amps and they both gave out about the same amount of power even though they were connected to the same power and grounds and one amp even stronger than the other.The amps are connected to 4 gauge power wire to distro block with 4 gauge out to amps..The 4 gauge is fused by battery with 150 fuse and distro block fused at 60A for power only. Remote wire is ran to amp1 and from amp1 another wire to amp2. Both amps turn on fine. Could 4 gauge not handle the power for both amps? Ive heard of people running just as much power as i got with 4 gauge..Why Would I not be getting enough power out of my sub amp but enough power in my speaker amp?
What Ive done(Failed)
-- switch sub rcas using the audiobahn rcas but using only 2 channels for sub
-- Instead of running 4 gauge from distro, ran 8 gauge
-- Hook up sub amp ONLY to just the regular 4 gauge power/ground with no distro blocks and only having the sub rca plug in on headunit/amp(sub was still not putting out enough power as it should)
-- Switch amps between Alpine mrp-500 and kenwood kac-9013d while it was hooked on the distro blocks with the speaker amp. Still gave about the same amount of power to my subs even tho the kenwood is stronger. They both sound like they were only giving my sub like 100-200 watts..not loud at all but there was bass.
-- Double checked just about everything from connection to amp,connection to distribution blocks, connection on the battery, settings on amp and headunit,making sure rcas were correct,making sure positve/negative was correct,settings and gain on amp were good
-- Did not turn the gain on sub amp past about 70%, I know not to turn the gain all the way. Even at 70% it was not giving enough power, my rear view mirror should be shaking
Thats all i can think of right now that ive done..maybe done a few more minor things..Its been a headache and i cant figure out why my sub isnt Bumping. I know nothings wrong with the wiring inside the sub box because i had it hooked up to the soundstream amp bridged which puts out 500w rms. It sounded amazing loud you could hear me from down the street. I just decided to power all my speakers with the soundstream and have a mono amp for the sub...
