Twistedmister Posted September 28, 2018 Report Share Posted September 28, 2018 So I'm listening to music and dialing in the max I can give my subs. I just installed an hcca 3k woth 3 skar evls, and everything is fine. Then from one song to the next I have very little bass. If I turn it down the bass cones back. If I turn it up bass goes minimal. Not completely gone. Sounds like I have less than 1 sub. Been running the system for a few days with no issues. I have: 250amp alt Regular front battery. Not sure what A power xs 925 for the back 3 runs of 1/0 gauge from second battery to amp all fused. And 3 runs of 1/0 ground to amp. 2 from battery 1 from fat seat belt all ground down and shiny. Any ideas? Could it be a loose... something that's interrupting power draw? Tia fir any help. Link to comment Share on other sites More sharing options...
DiBo Posted September 28, 2018 Report Share Posted September 28, 2018 You're dropping the voltage on that "HIGH CURRENT COMPETITION AMPLIFIER" into the danger zone guarantee it. I have an XTR 2500.1dz and I need a xs xp3000 minimal in the back and another AGM up front. You need more reserve bro. A lot more. Get your battery bank up.

blarg456 Posted September 28, 2018 Report Share Posted September 28, 2018 Need more power. Your second battery is way small for that amp. Link to comment Share on other sites More sharing options...
SkarredSierra Posted September 28, 2018 Report Share Posted September 28, 2018 Another issue is your seat belt bolt ground. That may work 4 low power draw bot that amp draws alot. Relocate that ground to the frame. Link to comment Share on other sites More sharing options...
finkster Posted September 28, 2018 Report Share Posted September 28, 2018 Did you do the Big 3? Also, do you have a 1/0 run from the from battery positive to the back battery positive? Get rid of that seat belt buckle ground and find something on the frame -- make sure the metal is bare and sanded down. 3 runs of 1/0 from the rear batt to the amp is way overkill unless I am missing something. What impedance are you running the amp at? DAT 4125------>RE XXX comps active Eclipse cd7000 I serve drunks for a living Link to comment Share on other sites More sharing options...

His particular amp has 3 power and ground inputs. Link to comment Share on other sites More sharing options...

Twistedmister Posted September 28, 2018 Author Report Share Posted September 28, 2018 So my front fuse popped. So it was running on the rear battery alone. I forgot to up the amps on my front fuse when I switched out the amp. But I am dropping below 12 sometimes on the rear battery. Sometimes. So I'm going to get a bigger one. I wish the made a big low profile one like the 925. And the bolts actually hold the rear row of seats on. So I'm going to double check but that should be frame. Thanks for the help guys.

Do you think one more d925 setup would do it? Link to comment Share on other sites More sharing options...
