tortoracer Posted May 31, 2012 Report Share Posted May 31, 2012 hey guys, i have a pair of kicker CVR12's paired with a kenwood KAC-9105D. At high bass volumes the amp just cuts out, and i end up with no bass until i lower it down...i need more power im pretty sure. what can i safely push for wattage without damaging the subs, overloading my alternator and needing a new one, or breaking the bank. about my car, its a 1999 BMW 528i, so its hard to get bass in there anyways, stock alternator, and for a 4 channel amp i have a sound-ordinance M-4075. my headlights dim barely at the highest demands (havent noticed it too recently, but at one time i have seen it). main concern is my subs, i dont want to blow them, and my alternator, i dont have the money for a new one.

Riley Evan Houser Posted June 1, 2012 Report Share Posted June 1, 2012 (edited) How many amps is your alternator? Are the CVRs dual 4 ohms or 2? I would love to help you out on this one big guy Edited June 1, 2012 by Riley Evan Houser Quote Link to comment Share on other sites More sharing options...
tortoracer Posted June 1, 2012 Author Report Share Posted June 1, 2012 (edited) i have found no information on my alternator even after a bit of research, but it is a 1999 BMW 528i, nothing too big for an engine, so cant be too powerful of an alternator...any way to tell for sure? also, i have these exactly (but dont remember getting them that expensive, even on sale) http://www.crutchfie...124.html?tp=111 EDIT: i think its 120 amps Edited June 1, 2012 by tortoracer Quote Link to comment Share on other sites More sharing options...
Trey_Dog650 Posted June 1, 2012 Report Share Posted June 1, 2012 see how much your voltage is dipping did you properly set the gains?

Riley Evan Houser Posted June 1, 2012 Report Share Posted June 1, 2012 Hmmm.. You could pop the hood and look directly on your alternator and sometimes it actually just says how many amps it is..sometimes not. Generally, stock is usually 105 amps.. GENERALLY, sometimes less, sometimes more. For instance, my 1992 Buick Regal is 105, my dad's 04 Grand Prix GT is 125, and my 04 Pontiac Bonneville is 140 (because I have air ride suspension) So I'm gonna guess and say yours would be 125 or 105 because you said you lights have possibly dimmed before.. In my Buick I ran a 1200 watt Concept amp and a 480 Jensen amp..but at RMS output it was around 1000 and they dimmed a little when the bass really hit. You have dual 4 ohms, did you have them wired in parallel or anything of the sort? Quote Link to comment Share on other sites More sharing options...
tortoracer Posted June 1, 2012 Author Report Share Posted June 1, 2012 oops a few posts, so most likely no looks at my edit the alt. is 120 amps according to realoem.com (the oem parts site for bmw's) not sure about voltage drop, but i think that the alt power is known so i dont need to check now? (i can if i need to) gains set properly, but whether the gain is high or low on my subs' amp when they reach that special volume they cut out, this does point to volume, right? if you look at the picture of the amp, it is a 1 channel, but it has 2 outputs (they are wired together internally im pretty sure), and i just hooked up the sub's to those...so yes wired parallel.

bassface Posted June 1, 2012 Report Share Posted June 1, 2012 Do you have an extra battery in the back? Quote Link to comment Share on other sites More sharing options...
tortoracer Posted June 1, 2012 Author Report Share Posted June 1, 2012 i do not have an extra battery in the back, nor any capacitators (useless?), nor the big 3 upgrade. i plan on selling the car somewhat soon (yearish) and removing everything and putting it in my next car. although i do not have the big 3 upgrade, i have read from the alt to the battery is already 0 gauge wire....not sure if there is any more to that upgrade.

Riley Evan Houser Posted June 1, 2012 Report Share Posted June 1, 2012 (edited) 120 amps that fairly solid for a decent system like which you have. Here's what I would do man, wire the coils in parallel so then each sub is 2 ohm then run them into the amp and they will be paralleled again down to 1 ohm. Give me one minute and I will look into an amp for you Also, what's your budget so I have a better idea man Edited June 1, 2012 by Riley Evan Houser Quote Link to comment Share on other sites More sharing options...

Don't get caps man, they slowy out more and more strain on your alternator. Big 3 is what you need to do man, no doubt. It's totally worth it Quote Link to comment Share on other sites More sharing options...
