Which is better Passive or Active? After askin on other threads i figured out the difference, but not sure which one is best. All i can figure is Passive would be better because you can use one channel of amplification and get 2 or 3 way crossover, and have that one channel power 2 or 3 speakers. So = better use of power. For Active you need one channel for one speaker. so more power is required by needing more channels, but that give you more control, right? Will one sound better than the other?

I have a 5500watt amp that is 70% efficient which makes 3850watts to use. I have a 250amp alternator and my car uses up 27amps of that alternator so i have 223 amps from my alternator. i have replaced my BIG 3 with 0 gauge, and will have my system (an 18" Fi BTL dual 2) ran with 0ga and the speaker wire in 10ga. If i worked everything out correctly using 13v i should be looking for a 31ah battery but i know that i want to go much higher to run off of my battery and not my alt. What do i look for in a battery? and if possible what kind would you all recommend? should i use more then one?

I dislike the dimming of my lights and i never want to it happen again. Right now i have 3 Fi SSD's with a RF t1000.1BD and a T500.1BD powering them. I have a 200Amp Alt and one optima yellow top. I haven't installed the equipment yet, so i don't know if it will dim. I have 2 electrical fans that drop my volt gauge from 14.5 to 13.5 and when i have my lights on theres no volt drop at all. Considering the fans draw 20-30 amps each, that isn't that bad. I have the Big 3 upgraded with 0/1 awg. Grounds from my frame to battery, body to battery, block to frame, and frame to cab. I have damn grounds everywhere The real question is, i want to be able to run my fans, lights, ster…

im looking for someone that has ever used a Quantum Audio 4000watt amp or any of the amps at all... im just wondering if that put out anywhere near the rating? thanks

I've been reading and reading and I guess I haven't really seen it explained in a way that I understand 100% so I must ask. Let's say I have a dual 1 ohm sub, If I wire it in series to a pair of strapped amps each amp will be seeing a 1 ohm load right? When I wire it I simply sire in series to the 1st amp and just run the RCA to the slave amp?

I was wondering if the IA20.1 is underrated? Looking to get one to power my DD9515 d2 subwoofer. Also, does anyone have one they would like to sell?

hey guys ill be running a Jbl 1200.1 watt amp at 1117 watts rms at 2ohm on a fi bl 18in do i need to get a new altenator to power that amp or will i just be fine with a capcitor ill be running this while the car is on. i hope i just can use a capacitor cause my money budget is low

so i have 2 18" fully loaded BTLs waiting to be put in with 2 2400 watt rms hifonics amps....1 amp for each sub... but i need to know how many batteries do i need ?? also what brand / model ?? i know XS Power Batteries but which model ..im thinking the HC2400 for each amp ??. i wanna get 1 battery for each amp ... and then 1 battery for my cars electrical... also how many amps does the alternator need to be ... i know i need to upgrade the alternator.... im pretty sure i wanna go with DC Power alternator ive heard nothing but good things about them... what brand ?? where can i get the alternator ?? also what gauge does the speaker wire need to be ?? 12 gauge fine ?? im no…

Well i sent the piece of junk db electric alternator back and went for a dc. cant wait for it to show up ill be sure to get pictures and even a video. from everything i see it should be awesome cant wait.

So I'm going to buy a new car but before I do I want to finish buying everything i need for my system (alt+batts) my current car has probably 70amp alt and I'm wondering if it would be ok to hook up everything without a ho alt until I can get the new car really my concern is with ruining the batts (5 duracell amg 105ah g31) I'm getting a CTEK battary charger so could I just charge them every now an then or would it be to much strain on the batts? Thank you for reading Current alt 70-80 amp 5 amg duracell 105ah per Audio qubed q1-7000 2 sundown xv1 18s

how are they? do they have good SQ they throw their rated power? do they sound accurate? is it worth to pay the expensive they are?

i have a ram mega cab and a sundown 2000d amp. what is the best 12in sub.

I recently caught a GREAT deal on one of these.. only problem is that the CD player isn't functional. That isn't an issue at all considering it's got USB & iPod inputs. However, I tried plugging a thumb drive into the USB input & it won't read it. It shows iPod when I connect it but you need the iPod integration cable to use it, so I know nothing is wrong w/the USB input. Does my flash drive need to me formatted a certain way? Do I need a certain thumb drive? Why isn't the one I've currently got working? This is the drive I'm using: http://www.walmart.com/ip/Sandisk-4GB-Cruzer-USB-Flash-Drive-Aqua/16648010

Hi guys, I've been driving a lot more now and I was looking to get some better sounds since my current set up is factory. I'm hoping to spend around $600 NZD (~$400 USD) on it all.

Will i need an aftermarket alternator if im running a hifonics bxi2608d? at around 2200~2400 watts in a 2000 Hyundai sonata with 1/0 power wires and Big 3 upgraded.....

ive been told that this is a good amp for the money im not sure if this has been posted yet or not haven't seen it. but i here its just about the same as the saz 3000d but cheaper. ive called the place and they said a couple people that have fi subs bought this amp and have good reviews on it. i mean the amp looks good he told me its just as the saz 3000d they don't believe in charging a lot of money on their amps it comes with a two year warranty whether i have it or i give it to someone else i just wanna know if anybody here has had any experience with it personally?? thank you Crescendo Audio :: Amplifers :: 3KWP Monoblock Amplifier

i wonder if it will be ok with a 1.3 ohm load... a friend wants me to put three single 4 pr12's in his x-cab ranger, he already has the mtx....so what do ya think?? 1.3 close enuff to 2 ohm to be alright?? wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Ok I'll explain what is in his car, Alt is stock for now (his excessive amperage one just blew, again) Batteries are two kinetik 2000's( one up front one in back) Runs of 1/0 and 3/0 to the back Big three in 1/0 3/0 wires and 1/0 wires and 4 awg wires to amps Head unit is a double din pioneer and 3 premiums on the back, Subs are two 15" dc xls dual 1's Amp for subs is a saz3500 Door speakers are kicker coaxials powered by a boss 2 channel He has four 6" selenium mids powered by a jl audio 2 channel And that was his setup and everything has been going fine. Now, he just bought two selenium horns and two selenium supertweeters (st200's) and a Boston acoustics amp fro…

Hi, I drive a 2005 e91 BMW 320 Diesel Touring. Stock Allternator with 120 Amps (Diesel) and 1 Kinetik HC 1400 and AWG 4 Power Cables(idk for sure, in germany its measured in square mm, i have 51 mm2) for OEM Batt to Kinetik Batt and from Kinetik to Amp. I want to know if i should do some upgrade to run a Rockford T20001bd perfectly. I'm gonna get a FI BTL 15 soon and don't want to smoke it up because of clipping... I already searched for a HO Alt but wasn't able do find s.th. for my ride. And sorry for the perhabs stupid question, but what the heck is or are the big 3?? Any Input??!?! I would appreciate!

I was thinking about purchasing a SAE-1200dv2 from dB-r and I noticed that the refurbs they are selling don't come with a bass remote. If I were to buy one where could I get a remote? Straight from Sundown/Jacob? Thanks

I just hooked up a rf t40001bd amp in my car, the amp is ran by 3 stinger sp1000 batteries and a 250 amp alt. I played it for a good 40 minutes I than went out to listen to it again and pop the amp smoked and the fuse discolored (but never popped... not sure wat else Im scared to put another amp in... Any help would be appreciated

My new amp (Aq1200d) came in. Verryyy nice. Not a whole lot to say about it yet besides that it seems to push alot more than my old bxi and seems pretty reliable. Looks fantastic. Thumbs up to the guys at Audioque excuse my dirty carpet, it will be cleaned soon.

I was checking out weldingsupply.com, and I'm stuck between #1 and 1/0. Their "suggested ampacity" chart recommends #3 for up to 150 amps, #2 for 200a, #1 for 250-300a, and 1/0 for 350a. But going off these numbers, it looks like at most I'd only need #2, as my amp has 5x 30amp fuses (leaving 50 amps of headroom). On the other hand, this site makes it look like I'd need 1/0 for sure. Sundown said use 1/0 for sure, just wondering if anyone else could weigh in on this, since I can't find a reliable table for ampacity and wire size.

So the other day I was messin' a but with my audio equipment... I noticed a very distinct buzzing coming from my front stage amp... realizing this could be a number of issues, I've ruled out the wiring already... I am going to take this time to upgrade my amp from the Kenwood 4ch to a Soundstream 2ch... Was looking into the Sundown 125.2 but for the money the Soundstream has more headroom.... This is the amp... TRA800.2 : Specs are as follows: * OUTPUT (WATTS):RMS @ 4 Ohms: 200x2 * RMS @ 2 Ohms: 400x2 * RMS Bridged @ 4 Ohms: 800 X 1 * T.H.D.: < 0.02% * Frequency Response (Hz): 10 - 50k * SIGNAL TO NOISE RATIO: > 115dB * DAMPING FACTOR:…
