I have currently a 250 amp fuse on my wire from alt to battery, would upgrading to a 300 amp fuse help or hurt in anyway? Does a bigger fuse give me more amp current to the battery (off a 180 amp alt)?

Ill be getting my 270a alternator in Wednesday and was wondering what size fuse to use for the wire between the alt. & batt. I'm assuming a 100a ANL will be insufficient when the alternator is running full tilt.

Got about 12-15 feet of 2/0 run from battery to trunk, going to be running DSC1500.1D @ 1 ohm 1500 rms and DSC280 @ 4 ohms 160 rms. What size fuse should I put next to the batt? Was thinking 250 amp, would that do it? Thanks. If it matters, stock alt 80 amp, Yellow Top 55 ah, Big 3 done in 2 gauge welding cable.

I have a JBL BP1200.1 powering a rl P-12. From battery to amp is about 9 ft and ground is about 4 ft. The amp's plug looks like its for a 4ga. Should single 4ga runs be sufficient? if so, who wants to buy some 1/0 and sell me 9 ft of 4ga??? (from the old setup)

I just ordered an Audioque 2200d and I want to order the wiring kit now, not when the amp gets here and want to know what size cable does this amp take? I'm speaking of the main (+) and (-).

ok, for setting gains with the DMM method, do i use 0dB tones, or can i get away with using, say -6dB or -3dB tones? I've heard recommendations for using as much as -6dB tone (that seems a little much to me) so i guess what I'm asking is how loud does most music get? does it regularly hit 0dB, or more like -3, -6, etc?

I ordered a 270 Amp alternator from Singer a little over a week ago, and he said it should be ready for shipment by the end of this week. I'm looking to upgrade my battery under the hood now, and in a few weeks throw another one in the back if needed. there's a ton of batteries to choose from...and from what I've read around on this forum you want a AGM/Deep Cycle batteries but if thats all your looking at there's a LOT of options. So my question is what specifications from batteries should you look at when related to car audio, right now I'm looking at a DieHard Platinum. What specs should I look at when comparing this battery to say, a Yellow Top Optima? Is t…

I had originally planned on buying a Q2200.1D to power my Ethos. After reading a thread of clamp test numbers and seeing it puts out less that 1.6k after box rise and voltage drop I'm not so sure any more. I've been looking through ads on a local audio FB page and found a SKAR 2500 for less than I'd pay new for the SQ. I know SKAR isn't well liked because of the owner, but I'm not putting money in his pocket. Just looking for the best bang for the buck. Whatever amp I decide on, what should I look for/check? I've always been leery of buying used, but I could stand to save half the cost of a good amp.

Hey everyone, I was at the USACI/Second Skin show this last weekend, and I won a couple SSA subs, the 12'' DCONs. Anywho, I wanted some input from you guys as to what I should use to power it. A guy I know that works for Diamond Audio suggested this: Diamond Audio D3 600.1 Someone else said that amp isn't going to push enough power. So, what do you guys think. Any suggestions?

i just got my autotek mean machine 1500 hooked up to my 2 type r 12s and i got the ssf at 35 and the lpf at 80...what do you guys run yours at or suggest i run them at

What do I use for some wire terminals...? Anyone have a tut? I am making my own box and i plan on using screws like most of the other people, for a tight seal. It's urgent!

Looking to get a 40 amp fuse for my sundown 1500d. Looking online I can't tell wether I need and ATC fuse or a MAXI fuse, just wanna make sure I get the right one. Thanks, Nick

Is the Powerbass ABA-1 Bass Accelerator good, they are selling me one at a very good price, but want to know if its something useful

Would I need a H/O alternator or another battery to run an AQ2200D? The stock one is 150amp and im looking to either run an HDC3 18" or FI BTL 15" in an 02 Trailblazer.

What voltage is bad on amps.

I read the sticky but I wanted to make sure I was correct, I have a alpine type r 10" dual 2 ohm sub and a kenwood KAC-9104D amp which is 500 watts rms @ 4 ohms. So is it; Voltage = sqrt(500 watts x 4 ohms) ?

What was your favorite amplifier you have ever owned, and why was it your favorite? Just a fun topic that involves some retrospect. I was listening to my system, just taking it in today on the way home from work. I had to do too much thinking about my favorite comp set ever and still haven't really nailed down my fave, my favorite sub was simple, but the amp took a little thought. I had to weigh out a few, but the top few were definitely easy to recall. So give it up... The favorite you ever owned and why.

Ok so i got my aa-3,800.1 this is my first system where i will need to upgrade my electrical.. i dont have to much more money i can play with so what will i deff need to power this amp? i will be pushing two 12 DSS Ethos.. and i have a alpine 4 channel for highs... not trying to half ass it but i dont have much doe i can spend.. i have asked a few people but i get differnt answers... so what do u guys think ill deff need?

what wire should i look into? im not really sure how to ask all these questions so lemme know if i get confusing. im pretty sure im running 1/0 gauge wire from my battery to my amp. (my amp is a sundown sae 1200 v2) .....let alone what fuse to run?? now what size and kind of wire to run from my amp to my sub? (sub is a 10" fi bl) ALSO what RCAs to run??? there are SOOO many brands and so many options. (i have an alpine ida x001 headunit if that helps too) i also am not sure how much wire i need for anything yet. just curious what i should look into. i plan on measuring out how much i need tomorrow. i know there are a lot of questions and i prob said something confusin…

I was just wondering what's the biggest wires you guys can use for the sub to the amp and the wires for wiring the dvc terminals together (if you have dvc) the biggest i've seen were 8g, is that the biggest it can go?, personally i never tried this so i wouldn't know and im planning to upgrade my wires sooooooooooon

I have a DD M3a and when I see set ups on youtube or forums they have 3k or 2.5k or 4500Ds I want to know if my amp is around the same as the ones they use. So my question is what is the DD M3a similar too in output, their site says 2200 at 1 ohm, but everyone says they are underrated and get to 5k at .5. And lets assume my electrical is good enough for a .5 load. What amps would be very similar? SAZ-3500D? DC 3.5k?

What would be a good amp to run for 4 aa 8"s d4

I recently purchased a fi bl 15 with the cooling option and was wondering what might be a good amp for it thats under 300 shipped. I was looking into the audioque 1200 but it seems as if not many people have experience with them. All sugestions are welcome. The sub is a dual 2 ohm and going into a ported enclosure around 3.5 cuft(tuning suggestions welcome as well) maybe bigger if i can fit it, theres not too much trunk room in my saturn sc2.

My current car is running off the stock 80 amp alternator. I am planning on soon putting 1200 watts RMS through the system. How will I know if I need an extra battery, or new alternator, or what? Thanks.

i bought a new zed audio amp at the beginning of may. zed was giving away free refurbished amps with a new amp purchase. i got a free us acoustics amp. i bench tested the amp as soon as i received it and it played music fine. i put it back in a box and never installed it. on june 2nd it sold on ebay for $160. the guy left me good feedback on june 12th. on august 7th the guy PMs me on sounddomain and says that he finally got around to hooking the amp up and it blows his power wire fuse (the amp doesnt have onboard fuses). i respond immediately, telling him how i tested it. i asked him to measure the resistance of the inputs with a dmm, and look at the circuit board for a…
