Hi I am planning to run my mono amp @0.5ohm (soundmagus vs3500.1) Right now alt. is stock, main batt. is Varta AGM 60ah and there is 1 run of 0awg power cable.. fused 150A I will modify my stock alt. at a auto electric shop.. Can electricians do this? (no aftermarket alt. for my car...

Hi everyone Sub stage: kicker zx1500 & 1 type-r. I used this setup no problem for 3 months. Today mono amp started to cut off and work again randomly. (regardless of volume & bass level) Every connection and my electrical seems fine. When I turn the amp's xover down to 35-ish HZ the...

I mean using 4 channels to power 2 comps. Focal's Passive crossovers have this feature

Hi, I have a 2-way component set(focal 165fx) It's xovers have bi-amp feature. HU is pioneer 8700bt and 4ch amp is helix db4(50wrms x 4) I am lost at bi-amping. I guess I have to connect 4 rca outputs to 4 rca inputs of 4ch amp. Then ch1&ch2 speaker outputs to 1 component xover...

I would love to have 2 18s.. hell even 1 18 in a tiny hatchback should be more than enough. (with good electrical&box) Sp4 looks nasty.. I've seen that in a lot of crazy builds. Maybe pay before I arrive to Vegas? I really want 18s.. but can someone recommend me a suitcase that can hold...

will visit Las Vegas and I just found out Vegas is home of Fİ oh wow:crazy: I remember when btl & bl & ssd were extremely popular on forums. It looks like they are still great. Hand built in Vegas? SMD forums mention Fi a lot. Some guy said ssd is way better than xfl others said xfl is...

lol never taught this thing would be worse than nicotine addiction story: At college, installed a stupid system like all young dudes did. Most of them had fun for a week, blew the sh.t, and moved on. But I couldn't lol. On and off this hobby went on and now nearing 30 yo., I should just stop...

Hey everyone, I had an Alfa Romeo 156(105a alt.) with big 3. It had hifonics brx1208d. At 1000rms@1ohm lights dimmed and eventually, alternator died. Now I have a vw(90a alt) with big 3. The amp is kicker zx1500.(I set to 1200ish rms@2ohm) Loudest songs playing full tilt and voltage drops...

I used "Torres Box Tuning Calculator" It is a good program for free. Google it and check it out

Subs will be underpowered.. Nevertheless, output can satisfy most people I think.

that makes sense. 0awg was clearly overkill I have only 1 amp(kicker zx1500.1) and with stock alt current will be low I think. so 100A - 150A would be fine I guess? Some people say fuse needs to be at alt... But fuse at the battery makes sense too. Ex: An accident and wire comes loose from...

Hi, I have done big 3 upgrade today. Car: 97 vw polo stock 90A alt - 72A batt.. new wire is 0ga and I want to fuse it. So I guess 100A fuse would be ok? and it should be close to alt right? Thanks!

ZX1000.1 Signal to Noise Ratio -62dB ZX1500.1 Signal to Noise Ratio -55dB ZX2500.1 Signal to Noise Ratio -65dB maybe noisy by nature ?

well I tested with hifonics and same things happen.. but much more hard to hear. Whine noise is there but noticeably less than kicker, especially when no RCAs connected. hifonics xover increases noise&volts too.. interesting, I didn't knew it had such effect. So I had to set HU lpf 200hz...
