Sub cutting in and out?
[Question]
Today I was driving to school and all of sudden my sub just cut out. about every 5 minutes or so it would come back working normally but that would last a minute and then it would cut out for another 5 minutes. Could this be due to my wiring?

yes, sounds like you got something crossed.

myiq2high @ 2009-03-11 10:06:02

sounds like a wire might be loose, id check all the wiring ground, power, remote, speaker leads, my amp did this too me once and it was my remote wire was loose.

caraudiosuperstar @ 2009-03-11 10:06:44

Quite possible. Check the wires going to the subwoofer. There could be a short (pinched wire or strands touching) causing the amp to go into protection mode.

what is your sub impedance? how is it wired?

what is your amp class A/B or D ...mono block or 2-channel bridged?

Reaper-Racing @ 2009-03-11 10:06:50

It could be that you have a loose wire or maybe the amp is going bad.

I had the same problem. Everything worked great for 4 days. All of a sudden its cutting in and out. It ended up being a loose power connection at the in line fuse near the battery. Tightened it up and it works great again.

what type of box for my subs?
[Question]
ok i keep hearing people say that , is important what box to choose cause of the sound of it , is this true? and if so which box is better i got 1 15 sub?

it all depends on what brand and watts.

Armando C @ 2009-03-11 09:33:12

PORTED WILL PRODUCE MORE BASS BUT BE A LIL SLOPPIER IN SOUND QUALITY, SEALED WILL BE A TIGHTER, CLEANER BASS........ITS COMPLETELY UP TO YOUR PREFERENCE....MORE BASS EQUALS PORTED

CLEANER BASS EQUALS SEALED

caraudiosuperstar @ 2009-03-11 09:33:53

the cabinet is what ever the sub is best designed to work in....



make sure you go over the specs of what sub you are purchasing or thinking about ...before buying

Reaper-Racing @ 2009-03-11 09:40:19

usually you can work out an approximate volume depending on the amount of watts being run. i have a 12 inch Ground Zero sub which is 500W rms and find that my 27 litre box sealed produces by far enough bass yet is still fast and crisp if thats any help

do u need a fuse for an amp power wire?
[Question]

JoHnNy @ 2009-03-11 08:58:54

[All Answers]
YES

Steve S @ 2009-03-11 09:05:42

yes u do. for any amp if do not u may burn ur amp

Armando C @ 2009-03-11 09:07:15

i would recommend it yes, although a lot of amps have a built in fuse, an in line fuse makes positive u don't kill ur amp

D T @ 2009-03-11 09:12:11

Yes, you need a fuse for your amp's power wire. Here's how to figure out the size you need, or at least, this is how I have heard to do it. Look at the size of the fuse(s) on your amp. Say for example..the rateing of the fuse is "40" amps. You need a 40 amp fuse...haveing a little higher won't be too bad. Just remember, that the bigger the fuse, the more power it'll take to blow that fuse, thus, resulting in more damage to your amp, and whatever else you have running off of that one power wire. Go with a little lower. If your amp has more then one fuse. Like...a total of 2 or 3 fuses, just add up all the values. Say for example...two 20 amp fuses...makes 40 amps. Grab a 40 amp fuse, or a little less. But not too much. if the the fuse rateing is too low for the wire's currect draw, the fuse will blow instantly, or the second you start to turn it up. Another rule of thumb...always make sure the fuse is no more then 18 inches away from the battery.

Hep with choosing the right Amp?
[Question]
ok i got 2 15 subs but i only want to install 1



this is the sub specs



450 watts to 900 watts max

2" parabolic RFL Voice coil

60 oz magnet

4 Ohm impedance

sensitivity 98dB @ 1 Watt. 1 Meter



now remember i'm only installing 1 15 sub not 2





my problem is i dont know how to choose an amp what do i have to look on the amp that will fit this sub, i'm buying it online cause is cheaper , can someone explain what is it i need to look for when comparing to which amp fits the sub, what is 2 channel 4 channel? any help is apreciated thanks and another thing when choosing a amp cable kit can i pick anyone or any in specifix??



thanks for the answer.

OKAY THIS IS WHAT U LOOK AT>>>>>>u have a 4 ohm sub, and its 450 watts rms.........so go with an amp that puts out roughly 500 watts rms at 4 ohms.....it should be a 2 channel amp or a monoblock amp, remember u need 500 watts rms at 4 ohms, NOT 2OHMS OR 1OHM.... 500 watts rms id do atleast 8 gauge, 4 gauge wouldnt hurt either,

caraudiosuperstar @ 2009-03-11 09:32:23

Actually buy a mono block amp( class D easier on cars electrical)...much better for running subs.



When using a 2 channel amp bridged to mono the impedance seen by the amp is half of the sub.....so look into a mono block amp that is two ohm stable so if you wish too add the other sub ...no issues will arise

Reaper-Racing @ 2009-03-11 10:03:44

Yes you need to look for a mono block amp.

And when looking to buy a amp kit make sure you get a good one,or you could end up with something like this.

TIS 1800w Amp / wiring?
[Question]
Does anyone know that amp? I was thinking about buying one, and I noticed a lot of the places that sell them sell them with the TIS wiring kit. But the power wire is 10 gauge. If I buy this amp, can I use that wiring kit with it? this is the amp:



http://stores.channeladvisor.com/thedeepdiscount/Items/tis%20t1802a%20rfb%20v1%20ca?sck=10403603&caSKU=tis%20t1802a%20rfb%20v1%20ca&caTitle=TIS%20Audio%20T1802A%201800%20Watt%202%20or%201%20Channel%20Bridgeable%20Car%20Audio%20Power%20Amplifier%202%20CH%20Stereo%20Sub%20Amp



And they have a 700 watt amp that comes with a 10" sub and a wiring kit..that is not the one I am talking about.

Just be sure to check what the RMS rating of the wiring kit is. If it is comparable to the RMS rating on the amp or less you should be fine.



If the wiring kit can handle way more power than your amp it is more likely you might fry it, although the fuses should prevent this. Wiring kits are fairly standardized except for the gauges of the wires on the ground and positive terminal wire. You can't really do any damage if done properly. Also, don't be afraid to go into your local car audio shop and ask them a few questions if you have any questions.

Joseph @ 2009-03-11 08:58:05

I have never heard of the amp, but I would suggest getting 4 or 2 gauge wiring. That will allow the amp to get the most power. If you get a smaller wire, it could restrict power flow to the amp.

Brian W @ 2009-03-11 08:59:57

TIS is highly overrated, if u buy the 1800 watt amp, its probably gonna be about 500 watts in reality, but with that said, id do atleast an 8 gauge kit on that amp.
