ive got a pioneer f910bt ill try the few things that have been said and see what happens

anyone got any more ideas

they sound very good dont sound distorted or anything. voltage seems fine.

yes i do, is this a problem?

the amp is just cutting off after playing it @ 55 on the HU. When I first installed the system is was working fine at 55 and this wasnt for a few mins. I have done the big three already.

so to get what i want i would have to get a higher rms amp and speakers. If i have it on 45 the vocals are drowned out from the bass. I want good bass which i have (to my standards) and still be able to hear the vocals when I really turn up the bass! if i turn down the volume on my HU could i turn the amp up higher?

Hey quick question; When I have my HU on 55 (out of 62) volume for a short period of time my speakers either cut out or my amp turns off. I have the amp turned up to half way maybe slightly more or less. Im just wondering what woud course this to happen. amp is fli 100rms per channel four channel speakers plye 100rms per speaker. With this i thought i could turn the amp up most of the way and have no problem because the rms for channels and speakers are the same. My ground is the seat bolt - which i sanded down to bear metal, bolt and car. is my amp crap - fcuked or something or am I missing something? I have posted an ealier thread about my amp and speakers i got told i could be clipping the hell out of my speakers so I did what the guy said to tuned my amp too so they shouldnt be clipping. any help in the right direction would be great.

well even with some of you moaning at me for my thread you have opened my eyes to what is needed to be loud....its not all to do with the sub and so fourth. I do agree thou, that if your so tired in threads like mine then dont reply you dont have to bitch at me for it. Yes, im not as well educated in the whole audio department and me being silly thinking of coming to a site where it has it own section for audio auestions and me posting a question about audio i was being a noob!! Is that meant to be an insult where im being called a noob - because you havent insulted me i am a noob at this. But you must of came outta your mother VJ and knew everything about audio. AMAZING! Im a noob and with in time im sure I will know a little bit more than I do know, I thought that was the intention of this audio section. for help, advise and other things. Next time just skip it and you wont have to worry your little head about it! Dont forget there are people out there including me that are new to all this..... I'm greatful for what has been said because it has gave me more information/knowleadge about audio!

Hi people, just wondering which subs would be louder considering the specs; sub 1 # 15" 4-ohm subwoofer # polypropylene cone with foam surround # power range: 100-500 watts RMS # peak power handling: 800 watts # frequency response: 20-200 Hz # sensitivity: 88.2 dB sub 2 15" # RMS Power: 400 watts # Peak Power: 1200 watts # Sensitivity: 90db # Frequency Response: 20 - 850 Hz # Impedance: 4 Ohm One sub is JL Audio and the other is fli. Which ever is the loudest I will get two of! )

Well cool, ill have a look in to that. considering im in the UK i wont be using the link. it would cost me more. thanks for helping the limey :-)

what sort of battery should i get? never done this before..I guess i would get two one for the boot and one for the front..

Ha ha ha,yeah that is noted just wanted to make sure I didnt leave anything out that was needed. Thanks alot for your help guys.

Right, cheers for the info. I will get a second battery and use that one to power my amps and stuff. Ill sell the 2.0 cap. Can you hellp with the other questions.....quite interested about the port hole

Hi to everyone, this is my first post on this site. I just have a few questions that im hoping that some people can answer for me as it will help me a great deal. I'm just going to do a Audio install in my car (focus hatchback) and I thought I would come on here and ask the question to make sure Im not going wrong anywhere. My plan..... custom sub box (not doing this my self but im having it made by a carpeter i know) not sure if I should get a ported one made or not??.. 2 * 15" subs.....Fli subs each 400rms peak power 1200 each specs; * 15" FLI subwoofer * RMS Power: 400 watts * Peak Power: 1200 watts * Sensitivity: 90db * Frequency Response: 20 - 850 Hz * Impedance: 4 Ohm * Mounting Diameter: 350 mm 1 * KENWOOD KAC 9104D MONO 1channel car amp amplifier 1800W ( To power the subs ) specs; # Rated power (4 ohm, 20 ~ 200 Hz, 0.5% THD) @ 14,4V : 500W RMS # Rated power (2 ohm, 100Hz, 0,9% THD) @ 14,4V : 900W RMS # Rated power (1 ohm, 100Hz, 1,0% THD) @ 14,4V : over 900W RMS # Maximum output power @ 14,4V : 1800W # Aluminium Die-cast heat-sink with Aluminium dress-plate # Power MOSFET Switching Power Supply # 1 ohm load capability # Gold plated RCA Line in & output # Gold plated terminals # Plug-type Speaker Level Input # Dual Mono Drive # Copper EE-Core Power Transformer # Toröidal Noise Suppression Filter # Ground Isolation Circuit # Variable built in low-pass filter (24 dB/oct.): 50 ~ 200 Hz # Infrasonic filter (18dB/oct.): 0/15/25 Hz # Variable Bass Boost (Variable gain): 40Hz, 0 ~ 18 dB # Variable input sensitivity: 0.2 ~ 5V 1 * Fli Loaded 900s 900 4 Channel 900w ( to power 2 sets of 5*7's) specs; Type: 4/3/2 Channel.

For this sort of setup would I neew to upgrade my alternator? (I have stock) I also got told that I should wire my subs as follows; possitive from amp to possitive sub 1, negative from sub 1 to possitive sub 2, then negative from sub 2 to negative amp....is this the best way? How could I find out what sort of gains I should put up on the amps without damaging the speakers or amps? With the wiring kit I mentioned above I will be wiring it two a splitter with fuses in so i can wire both amps from there....what sort of fuses should I use in the splitter and what size wires should be used to connect each amp? I have done a setup before But I want to make sure that Im doing it correctly and the best way. If I have missed anything then if you could let me know that would be great. As I have said I have done an install before but I still feel like a total newbie. I know I have thrown alot of information in but I tried to cover everything so sorry if most of it is no use... Thanks in advance for any help thrown my way....
