vroom Posted June 18, 2018 Report Posted June 18, 2018 So im about to install the biggest amps ive ever owned- dd m4 and a s4b. The m4 requires 2 0 gauge power cables a the s4b 1 4 gauge. I was planning on using a SMD anl fuse block at the battery and run the 2 0 gauge cables to a non fused distribution block at the amps and also run the 4 gauge to one of the terminals for the s4b, bad/good idea?

Skullz Posted June 18, 2018 Report Posted June 18, 2018 Might as well add another battery or three out back or more and use that as a distribution point. With that much power you will certainly need more alt power and capacity to maintain voltage. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2
AlpineNut Posted June 18, 2018 Report Posted June 18, 2018 If you are gong to be running those amps I would highly recommend having fuses near them, the DD M4 has no fuses built in where the S4B does. http://ddaudio.com/wp-content/uploads/2015/12/M3c-M4b-M5-Owners-Manual_0.pdf http://ddaudio.com/product-archive/series/product/s4b/ 73456w9vbwevsdb sodtbsorutnvsd sdtuspdun sd d f gsdfiusd gdf n
vroom Posted June 19, 2018 Author Report Posted June 19, 2018 So fuses near the amp and battery or just near the amp? I was planning on running the biggest XS or Optima battery with a 300amp alternator, will that be enough? Just to be clear im not competing just doing a loud daily driver
Crazy 8s Drums Posted June 19, 2018 Report Posted June 19, 2018 Depending on what subs you use and how you set them up, those two amps combined are approaching 5kw. You will likely need an additional battery. You could run two 2/0 from the front battery to the secondary battery (probably in back) and you will want 4 fuses total...1 for each 2/0 out of the front battery and an additional fuse each going into the second battery. From the secondary battery, run two 2/0 to a 4 way fused distro block, 2 fuses for the M4 and 1 for the 4 channel and the other for whatever or empty. It aint going to be cheap but those amps are serious stuff and you dont want to skimp. Orion XTR amplifiers Skar subs
vroom Posted June 19, 2018 Author Report Posted June 19, 2018 Would a large capacitor at the back with the amp be good enough? Or definitely a second battery?
Crazy 8s Drums Posted June 19, 2018 Report Posted June 19, 2018 No. A capacitor ain't going to cut it. A bank of them, maybe. That m4 is 5000w RMS and is going to need around 500 amps at full potential. The 4 channel will need another 100+ amps, give or take. Those little crapicators you see on the market, mislabeled as 20 farad or whatever...all bullshit..they aren't going to do crap to help you. Orion XTR amplifiers Skar subs
Crazy 8s Drums Posted June 19, 2018 Report Posted June 19, 2018 Using XS Power's chart, you can get an idea of what you are going to need... https://4xspower.com/support/wattage-chart/ You are going to have about 6000 watts RMS on tap with those two amps...and you need to consider what your car needs for driving too; lights, A/C etc...

Joshdashef Posted June 19, 2018 Report Posted June 19, 2018 I use a d3400 in the rear on a Mechman 240 and I'm only running a DC 2k (200A) and a P600x4 (<100A)... so i'd say get the extra battery / bank of caps SMD Tool Map (2024): https://www.stevemeadedesigns.com/board/topic/226545-smd-tool-map-2024/ Great Box Bracing Examples: https://www.stevemeadedesigns.com/board/topic/202148-best-way-to-brace-a-box/?do=findComment&comment=3055002
