When i turn on my amp, it makes a very high pitch sound, so what could it be or any suggestions Amp is a rf t1500-1bd, subs are 10 chaos, hu- jvc Ask what ever questions u need Thanks

Ok so i just bought the 3000 and it requires at least a 300 amp fuse. my question is where do i put it, do i put it right before the amp like i did with the battery fuse is not supposed to be no further than like 12 inches. i dont want to sound stupid but all the amps ive ever owned like a RF T10001 and hifonics and us merlin amps have always had built in fuses.

yeah, i know, not the best amp by far, but my cousin's truck go broken into, and his audison srx3 will be out of the picture for a little while. we have a powerbass asa 400.4 sitting around, and want to use it until we can get a new audison. now, for the big question... does anyone know if the powerbass in tri-mode capable/stable? we want to use channels 1 and 2 for the comps, and bridge 3 and 4 for a sub. a 15" dayton titanic mk III will replace the 12" type r that was in there, although a type r will be back again... probably. full system rundown 2000 chevy s10 ext cab clarion dxz775usb hu audison srx3... now gone diamond d6 comps in the doors, textile tweets, +3 to…

ok here is the scenario: im running 2 BLs off of 2 1000.1 kickers and am gettin some dimmage(only when i turn it up), everything is stock question(s): whats the difference between a red top and yellow top(which is better reccommended if at all)? or do i need to get an xtra battery and/or cap? should i go ahead and attempt the "big 3 upgrade" to see if it helps any? thx in advance, and sorry, im noob when it comes to this stuff

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…

i got my friend's stock HU from his civic cuz he got a new one and i want to install it into my 88crx but the back of his HU doesnt have wires hanging like most aftermarket ones, it has a slot just to plug the stock car harness into, so now what

Orion Xtreme 1400.2 XTR does anybody know the quality of this any thanks.

Alright guys. I picked up a Hifonics BXX2000.1D for my Fi BLv3 18. A good friend of mine has a scope, so we dialed in gains on a 0db 50hz test tone. I have the electrical to feed it. I’m able to maintain voltage at full tilt. I was reading about power and impedance rise and decided to clamp the amp and get some readings for myself. I’ll save you the time in telling me “it’s a hifonics amp, you get what you pay for... etc” I’m fully aware. I plan on going Sundown this spring with tax money. However, I’ve ran a few HF amps in the past and have been satisfied. I ran test tones at full tilt, 20hz to 55hz, measured AC voltage at speaker output termin…

I have it wired but it doesn't turn off when I turn the car off because its directly hooked up to the battery. I'm thinking I can splice into my remote turn on for the amp but I won't get a voltage reading from that will i? I need a way to get the best voltage reading possible and for the meter to shut off when the car is turned off... helpppppppppppppppppppp

alright heres the deal, I just bought a T shaped distro block with an 1/0g input and 2 1/0 outputs. I planned on on running 1/0g to a sundown 50.4 and a sundown 1500 but when i got the 50.4 today the power input looks like the biggest size i can use is 4g. So im wondering what the best way to solve this would be...can i just put 4g wire in the 1/0g output? or would it be better to get a different dblock? And before i order the 1500 i was wondering if it only accepted 4g max too

Can someone post some pictures of there big three setup and maybe explain to me on how to do it that would be great thank you!

Okay guys, i have a Fi 15" BTL with cooling, 3rd magnet, and hixmax coil with the dual 2 ohm. its the in a 6.5 foot ported enclosure, only 5 feet though after port and sub displacement. Its tuned to 39 Hz and is 1" all the way around with a 1.75" front face. Its also got internal bracing so im not worried about the sub blowing apart the box in any means. I am looking to spend around $500 at the most on an monoblock. I was looking at the hifonics BXi2607d which is 2600 RMS at 1 ohm, but i keep hearing bad things about hifonics and not so sure if i want to go that route anymore. Im looking for an amp to put out some serious power because i want this BTL to be herd from bloc…

Hey guys, just looking for an ok temporary (probably 6-9 months) to run a single Crystal cmpx2 15. That's going to be 1600 rms dual 2 ohm coils. My budget is around $150 I'm currently looking into grabbing one of the cheap Shark 2500's. Let me know if there are any other options you would recommend. Thanks guys, and I'll be looking for some box design help as well, but I'll open another thread with size reqs

whats up. i just bought a 95' taurus. im running two btls in the back seat walled off, powered by two saz2500s, and also a four chanell. i was just wondering how many feet of power and ground wiring i would need to power everthing. thanks

Im gonna order a ho alt for my 08 yukon but i wont have the $$ for batts till june..my stock alt craped out so i need the ho on there to run the truck. My question is if its ok to only have one battery? I wont fry it? Im buying a 300a+ alt.

Does anyone know what the accurate specs are for the sundown audio SAZ 1500d v.3 is? I lost the paper work for this and i've found 2 sites that claim to have the specs but they are different from one another. I'm just trying to figure out the accurate inline fuse to use and the accurate watts.

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.

Im looking for a list of banned amplifiers for the dbdrag street trunk class.. I cant really find a list anywhere and iv heard that american bass amps are ban in the street classes, but i cant find an actual list.

I been looking around for head units and I haven't found the "perfect" one. I currently have an Alpine 9883 and I wouldn't really buy it again. I use my Ipod and I dont like the way to select music on the head unit. I was on the Sony Xplod site and this head unit looked pretty cool. MEX-BT5100. Has anyone had experience or worked with Sony head units? Or if anyone has a better choice let me know.

I have a sundown x10 d4 in a 2.0ft^3 box tuned to 31 hertz. I have been searching for an amp to run this sub for the past 2 months and can't come up with anything on a budget. My budget is about 400$ and I would like to put 1500 rms on the sub at 2 ohms. I have a second alternator to just power my system it's just your average 150 amp with a run of 1/0 sky high to a xs power 975. Anyone have any suggestions for an amp?

I have my install next wednesday, and the problem is...I only have 1 d3100...and the place that I ordered the 2nd one called me and said that they shipped my 2nd one out...but then they called me back and said that they were sold out of the d3100, so they offered to substitute a d2700, my question is....can I install both of these batteries together for my xtra batteries in the back of my car...or is it wrong to connect 2 different model batteries together???????? damn im bummed right now Thanks everyone for the help Freddy

Looked around for a bit and decided to go with this dual rectifier alt from alternatorparts.com . I ran it via specs of their website ( BTW i got the Quicktifier210 with a 220 amp denso alt). Guy told me it would do full output at 1200rpm( 120 i think at Idle). I upgraded the big three and ran it all with 1/0 Knu Koncept Kolossus wire. I am not running much, Double din JVC HU and a lightning audio 600.2 on a single W0 10. Gain is set to half. Optima Red top batt. My ordeal is, that the moment I put it in gear everything dims. And, if i have a few things on ( IE. air, turn sigs, headlights) things seem to get a bit worse. I took the gauge cluster out and cleaned everythi…

I was looking to do a big three this weekend and was wondering how would you do the bir 3 when the battery is in the trunk. Does it take away from the whole idea?

So hoping others with more knowledge then I, could help clear up the wondering of my mind... What are the benifits of a person running a daily, (non-competitive) sub stage at 4 ohm compared to 1 ohm? Just curious if the pros were great enough, to dish out double the money for an amplifier? Thanks for everyones time and input!

I have a JVC KD-Dv500 head unit. It plays everything, including dvd's. It is dolby 5.1 ready, w/ the digital toslink output. I am looking at a PhoenixGold 5.1 amp for everything except my sub, that has the toslink input. SO, my question is, it I hook up the head unit to the amp with the digital cable, would I still need to use RCA's, or does the digital cable take the place of them? MattB
