DireRaptor22 Posted March 23, 2014 Report Share Posted March 23, 2014 Ohay guys, so... gotta couple of upgrades in my car recently... Mechman S Series 240 amp alt Big 3 upgrade 1/0 awg CCA 1/0 awg batt to amp CCA Duralast Platinum batt under hood 2 x Sundown SA-12 Currently running a BRX1100.1D, and I notice very slight light dimming when at full tilt with a heavy bass note/beat. Amp has been tuned properly with DD-1. I am about to upgrade my amp, either to the SAZ-2500D or the Q1-2200D. If I were to get a second Duralast Platinum batt, would the dimming go away? Eventually further down the road I will upgrade to XS powers, but don't have the funds at the moment. Any thoughts? Thanks! “The fascination of flight can't be expressed with words.

Skullz Posted March 23, 2014 Report Share Posted March 23, 2014 Not much you can do about the headlight dimming, if you want to reduce it to a minimum, you'll need to use some 8 awg wire to the headlight from the battery with a relay as close the the light as possible so it isn't snaking it's way through the car from the battery to the dash then back out to the lights. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
DireRaptor22 Posted March 23, 2014 Author Report Share Posted March 23, 2014 I just find it odd that only 1100W on a 240 amp mechman alt still causes dimming. Normally you can't seem dimming at all, but on extremely low notes (sub 30Hz) and loud beats at full tilt, it'll dim. I hear people say an extra battery solves this problem because it adds more power reserve since the alternator cannot "react" fast enough to the sudden demand of power during those heavy beats. Is this true? “The fascination of flight can't be expressed with words. But it really lies beyond the capabilities of human endeavor.

revoracing247 Posted March 23, 2014 Report Share Posted March 23, 2014 only way to know is with an analog volt meter. then you can see exactly what's happening to your voltage. or an O-scope would also work for that if you have one lol but those are even most expensive. but in retrospect you'll see a change in your headlight brightness if your voltage changes at all! even if it's just like 500mV when the bass hits edit: i should probably read your whole post before responding. if you wanna run a 2200 or bigger i'd definitely get another battery. im running an AQ220 and with 3 Kinetik 800's and my voltage drops to like high 12's on heavy stuff. but im also running stock 90A alt.

Aj11 Posted March 23, 2014 Report Share Posted March 23, 2014 your stock 90amp alt is charging all those bats? I'm shocked that op is still getting dimming, are you getting belt slip? jvc deck stinger 1800 front hc 2000 kinetic rear 2 runs of 1/0g big 3/4 ct 60.4 2 ct 1400.1 ct EXO 15 d1 lots of deadner type r comps front stage 6 kicker tweets rear stage lots of great stuff coming soon ho alt more bats ct comps for front stage more deadner sweet amp rack lots of L.E.D lights new deck (thinking 80 prs, or flip out) Link to comment Share on other sites More sharing options...
JakThomas Posted March 23, 2014 Report Share Posted March 23, 2014 check your connections . and what kind of voltage drop are you getting to you have a volt /batter meter? I hope to not be dazed by thingsthatglitter if i ever have more wealth than the low income. Link to comment Share on other sites More sharing options...
Rich Schenk Posted March 23, 2014 Report Share Posted March 23, 2014 Did you do the big 3. What are your grounds like? Do you have a volt meter?

DireRaptor22 Posted March 24, 2014 Author Report Share Posted March 24, 2014 your stock 90amp alt is charging all those bats? I'm shocked that op is still getting dimming, are you getting belt slip? I actually think I'm getting belt slip atm. When I first installed the belt it was fine, then it loosened up and started squealing at startup, so I tightened it and the squealing went away. Now, 2 weeks later, it's starting to squeal at startup again. It's also the proper sized belt recommended by Mechman. I guess I'll just have to tighten it up again. Yea, I'll need a volt meter to measure it, have to borrow a friend's. You think it's reasonable to have 2 Duralast Platinums running an Q1-2200D or SAZ-2500D with that 240 amp Mechman? “The fascination of flight can't be expressed with words.

bigmizzle99 Posted March 26, 2014 Report Share Posted March 26, 2014 The math says that amp will only pull Approx 101 amps at full tilt (using 75% efficiency). You've got 240 amps. There should be NO dimming at all. Either the alt isn't working or the wiring is serioiusly jacked. In your big 3, did you ground the alt case to chassis with 1/0? If not, you should. Then also make sure the amp ground is also 1/0. Camaro SS Build Altima build 2.0 Altima build 1.0 Link to comment Share on other sites More sharing options...
MECHMAN Posted March 26, 2014 Report Share Posted March 26, 2014 I would work on upgrading the duralast battery up front and possibly put a secondary battery in the trunk. 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...
