[QUOTE="858SD, post: 8218483, member: 659466"] 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.
