Came in yesterday, thought I would share. W.W.

So my friend just got a new Sundown amp. The recommended fuse size is 200 amp. He just told me on the phone he currently has a 60amp fuse on his fuse holder. He asked me if it was fine to use what he had, I said I was going to ask around first to see if it was ok to do so. Is it ok to use a 60 amp fuse or will there be any problem/risk or anything?

my mind keeps changing ever day while i'm trying to save on what amp to get. i know its going to be a sundown. but which one? i was leaning toward the 4500. but the used 3000's looked nice. now the 3500 seem to be offering a little more. so after looking, the 3500's do not have any fuses. i really dont like fuses because when i did, it kept blowing (it was a low amp like maybe 50 or so for the whole system, 3 1000w amps and a yellow top, after the stock battery). so i upgraded it to a 250amp monster fuse, worked perfect. i have seemed to have lost my fuse so someone said "Get a circuit breaker instead". just wondering whats your ideas on Fuses and on Circuit breakers.

This topic is to help a friend at work. He recently bought a 1996 Lexus ls400, he loves the stock system as far as clarity just wants to add some bass. It has a stock free air 8" in the rear deck but its guttless on any bass. He doesn't want anything outrageous just needs to get it bumpin a little bit. What do you guys suggest he do? He has mentioned maybe just find another free air 8 to replace what's there...who makes a decent free air 8? Maybe do a LOC and just add a sub and amp to the trunk?..but he has a stock amp and I have no clue how that works.. Another question he asked me was if he changes his stock head unit, will he lose the ability to use the stock amp and e…

so what would be the best way to run rca for 6 amps? HU has 3 rca outputs front rear sub, and if i understand corectly i can only do 1 amp in master and 1 in slave, so this would b ring me down to 3 for my sub amps what would be the next route?

Its a 2000 watt volfenhag amp. not sure of the exact model. i had it wired at 1 ohm, and from what i have read online the lowest it should be wired is 2 ohm. It started cutting off after 10 mins, then 5, then 2, then it stopped working. I took the cover off, to look for burnt pieces, but i found nothing. it all looked fine. now, what could cause this? can it be fixed cheaply? if not, could i repair a memphis pr 600 using this amps parts? im uploading pics now and yes, i know this is a POS amp, but currently im saving up to buy a fi btl then a sundown amp. ok, photobucket is being gay so ill get pics tomorrow.

OK. I know this is a HORRIBLE post and probably an open ended question... I am wondering what can be added to my setup to make it better "overall"? I am seeing a bunch of stuff about things which i have never heard of and am currently researching a few different things to see if something might be missing. My main thing is the speakers or rather all the settings on the amp for the speakers. Last time i was getting ready to install my system i just turned the volume ot the max I would ever play it and then started screwing with the amp until it sounded good. IIRC i had it switched to HPF and then just started tweeking the freq. and such until it stopped sounding like …

I need a new amp for my SI Mag. I had a Massive P1000.1 amp running it that does 880W @ 1ohm, but that amp is now powering my newly fixed Adire Brahma MKIII that Fi reconed for me and instead of getting a new amp for the Brahma, I'm thinking about getting one for the Mag. Now here lays the Problem. I'm down to these: Sundown SAE-1000 (1000W @ 1 ohm) - because I know Sundown is high quality. Massive P1500.1 (1250W @ 1 ohm) - because I've never had a problem with the P1000.1 in the year I've used it. and Hifonics BXi1206D (1200W @ 1 ohm) - largely because it's easy on the wallet. I won't ask which one I should get. I'm pretty sure EVERYONE's going to suggest the Sundow…

I have a 99 3 door Z71. I've upgraded the big 3 to 1/0 ga. I've put 200 amp Iraggi alt. in. I've got 2 Kinetik 1800's in the back. My amps are a RF T600-4, T1000-1. My volt meter still jumps alot and my lights still dimm a little. I just bought the 2 kinetik's new about 3 weeks ago. I put those 2 back there because I was planning on upgrading sub amp and 2-12's. But if it can't keep up with what I have there's no need. Is there something I'm missing to do or what? I don't listen to stereo very often with truck off. I just don't understand what's going on.

Alright, I just put a new Fi Btl 18 in my 97 dodge ram 2500. It is diesel and has a h/o alternator and duel batteries. I was using a power acustik OVN1 5500D amp. It is connected to a battery with zero gauge wire for both the positive and ground. The gain was only turned up about half way with the BTL running at 1 Ohm. I did not listen to it all that loud, however one day the bass cut out and then the amp started to smoke. I immediately shut off the radio and felt the amp. It was cool to the touch. The amp was only in for a week and had only been used maybe three times.... When I got home I turned the radio back on and the LED indicator came on but no power is coming out …

I have looked every where and have only found very few discussions and i know it puts out decent power for what it is. My question is this can it run at 1 ohm all day long beating? im doing a groundpounder in a integra hatch with 2 18" level 5 DC's and i have 2 of these. I am over seas on a deployment for the army at the moment so i cant wire them up or anything so i need to know if they can run at 1 ohm or not befor i order the 18s any advice would be greatly appricated!

Since im getting back into car audio. How does the new Phoenix Gold amplifiers compare to the older models like the M and ZX series? Reason im asking is it fits my budget plus a local dealer. I was looking at the RSD600.1 or RSD1200.1 to drive a pair of 12" IA Lethal Injection Series.

How do i know what size fuse to get? 20 amp or 300 amp? Is it a preference thing or what? Anybody care yo elighten me...

I have an old KENWOOD kdc138 in my Mazda Tribute currently .. It only has one pre-out which the manual says the pre-out is for the rear/sub signal out .. Currently I have a mono block that is receiving the signal from the pre-out. What I want to do is add an external amp for the front and rear with still keeping my mono block. How can I do this all with only one pre-out? Another question is what is the difference between the front signal and rear signal pre-outs on a receiver that has multiple pre-outs?

I have a chance to pick up a Ultra Linear UL1500X for $50 bucks and was wondering if it was a good amp and price? It would be used to replace my Earthquake PH120.2. to run 2 Earthquake dbx10 10 subs.

i have a client with a 6 battery bank in the bed and dual factory battery locations up front. he has 2 alternators and each alternator is going to its side battery so the driver side alt is going to the driver side battery and passenger alt going to the passenger side battery. i dont know - does having 2 point of voltage input going to two different batteries in an electrical system present any kind of issue? e.g. should these alternators be rewired to both go to a single positive terminal on one battery or is status quoe good enough? we are pushing close to 1200A at full tilt and are considering a 3rd alternator in an after market bracket (current two are in factory loc…

Hello SSA! Does anyone know if 12v 400 amp circuit breakers exist and where to get them? I've got a 300a breaker on the main 2/0 power wire coming from the alternator and front battery then going back to 5 Deka group 31 batts. At about 2/3 power with music, the breaker kicks. And for those who are curious, I'm running 6 BTL 15's on 6 SAZ-3500D's. DB

I currently have a 1000 watt Rockford fosgate. I want a bit more output from my xcon. will upgrading to a 1500 watt amp make a difference? I am planning on buying a sundown from db-r. any input what so ever is appreciated.

http://www.profilecaraudio.com/crossovers.htm i just need something to cross over my subs with, nothing fancy. what are yall opinions on this?

Found thisamp while browsing ebay and did not know much about power acoustik as a company. Are they any good? Thanks, Matt Cusack

Ok I was just wondering what you guys do. I bought some knukonceptz terminals. Here's the situation. Did you guys cut off the factory terminals? And then just wire those into the new terminals? Or get a battery with multiple posts? Its gonna be in a 08 scion xb so I don't really wanna cut the factory terminals if i dont have to.

I can pick these suckers up for 195 each locally, 12v and something like 1200cca ea, anyone every used these before? https://m.interstatebatteries.com/product/26-4163958589-4163958502-2147384763-4294492278-4251616327-4163992330-4163958586-4163958484-2147384903/8D-MHD Considering two for my truck because the price is DUMB considering they're 130lb deep cycles.
