Subwoofers are working but aren't that loud.. help me!

Me and a friend hooked up my amp and subs today I have 2x 12'' Rockford Fosgate Punches and a MTX amp 404 thunder not quiet sure the watts but should be able to handle them just fine I believe... but the problem is my subs are working sound coming out of them but there not beating like they should I mean my trunk should be vibrating when its on full blast and its not my Pioneer 6'' speakers and pushing out louder and more bass than my subs...which is sad when I close my trunk you cant even tell I have a sub or anything.. Someone help please, this was our first time installing maybe we messed something up I dont know..

    I'll tell ya everything we did.. Connected a wire to battery I bought one of those power blocker things with the fuse we connected to the the same wire then connected more wire to the other side to the B+ on the amp then we got a thin wire and connected that to the fuse we put into the fuse box for the remote" which didnt work" still stays on when I turn the car off, so I gotta pull that fuse everytime to turn the amp and all that off now" ok then we Grounded the what we were supposed to, to a bolt on the frame of the car.. Ran wire from the subs to the amp from both sides ( its rectangle box with both subs in it..) then ran the red and white audio cable from my JVC cd player through the car to the trunk connected it to the amp (only thing that looks pro was me running the wire through the car, cant see it at all :)) the audio wire from the cd player to the amp is rockford fasgate also..we put it into the sub outlet on the amp and we turned it on and nothing so we moved that audio wire to Rear outlets on the amp and they work but I mean not like they should ya know..

    The amp is a MTX thunder 404 thats what it says at least...I got the amp and subs from a friend used...well I turned all the nobs clockwise and moved the x over to lpf now sounds a little louder not what it is supposed to be my buddy came over a for a minute to listen he said that its not even close enough to being loud enough and he has installed alot.. he said he'd fix it for me for 75 bucks but I really dont want to pay that ya know when im so close and its prolly something easy

    I also that an equalizer thing but I dont know how to hook that up to the amp I have power, ground, and remote connected to it but cant figure out how to hook it up to the amp, thought that should help alot but I cant figure it out.... Also have an older Kenwood amp but didnt think I would need it plus I dont know how to connect the 2 amps thought I should at least figure out how to fix what I have going now before I hook up the other amp

This site is badass for helping the DIY’ers in hooking up their audio and setting it up right. It’s all about how your amps paired with your subs. If the amp and subwoofers aren’t paired together correctly your not gonna achieve the bass you want

Not a bad set-up at all. i can help you i do need some more info though. what head unit do you have? what type of box is it just the normal rectangle box with or without divide sealed or is it ported? measure the size of the box and give me the dimensions please? how did you run the cables and how did you hook up between the deck and the amp? does the amp have built in crossover this could be problem just a little tuning? if it does make sure you selelct lpf mode and turn the hz knob all the way down ( counterclockwise) check the gain control should be another knob turn it clockwise all the way. you might need a little flat screwdriver to reach all these. is this amp bridgeable and if so are you running bridge mode ( 1 channel) if not look where you hook up the speaker and look and both channels and you will see a pos connect on 1 channel and neg connect on the other, put both neg wires on neg terminal and put both pos wires on pos terminal. in this set-up you will have full raw power. let me know about this and i will help you the most i can. good luck and happy booming.

    aorry i lost the message i was typing to you. not sure if you got the previous message or not about how to get the amp hooked up to turn on and off with key? let me know if you did or did not, computer did wierd things. if you did you should be looking at the amp now. now turn the amp on the side where all the buttons and knobs are, you may need a little screwdriver start looking at the knobs that say gain / lpf hpf full/ 2 channel or 4 channel. turn the gain all the way clockwise, switch to lpf and select 2 channel make sure that the speakers are wired in bridge mode the corresponding channel that you have the audio cables plug into. out the 2 pos speaker wires together and same for the neg and install on that channel in bridges mode, pos will go on 1 conn. and neg will go on 1 con all this on same channel. speakers will work in reverse polarity sometimes really well and sometimes that could be the problem your having. double check that polarity is correct amp should say bridge mode and have a line going to proper terminals the terminal will be different. pay attention only to the bridge drawing or you will get confused when it shows you where to hook. give me the exact model # of the amp you have and i can help you more then this with more precision. example rtp 404 road thunder amp that rtp makes a huge difference with them. the rtp has got to go bridge mode or you will not have enough watts, only 45. in bridge you get 150. the other one is bigger then that need to know this. if you have the rtp 404 amp the you need not adjust the front gain your audio should be plugged into the rear to the right of that should be a switch that that says rear x-over move that the lp next to that is a knob that says gain turn it clockwise. using the pos speaker wires connect them together and install on the pos side of rear channel, using the neg speaker wires connect them together and install on the neg side of rear channel. try this and let me know what you get. you did say you had punch p112 x 2, as long as they are p1 punches then you should have enough juice if they are p2 or p3's then you may not have enough. did you buy the amp new or used? all right let me know what you get and i'll check back later with you. good luck

    are you still pulling the fuse to turn off the amp? my first letter to you said how to fix that but dont believe that you got it. you need to pull the deck out and identify the remote antenna wire normally blue or blue with white stripe and connect the remote wire from the amp to that. sometimes you will have two wire that look exactly the same turn on the igntion and using a test light ground the tester and turn the radio on until one turns the light on. once you have found the one that does boom there you go. now the amp turns on with the key. dont worry about the equalizer right now, sorry but i've never been a fan of them at all. they dont do that much and are a pain in **** to tune in, a good active crossover ( wired pre-amp) is a huge help though. for now though lets get you up and booming. have you checked to make sure that the speakers inside the box have the wires on the right terminal pos on pos, neg on neg. if that checks out ok then check the knobs that you turned im going that you do have the rtp404 amp, is there a knob that says something such as lpf gain or lpf level or just level if so reading those numbers turn the knob to the lowest setting normally 40hz, while keeping the gain turned all the way up. yes your right we are close to getting you up and running. what type of deck (head unit) are you running so i can make sure that there is no settings in there that we need to change???? let me know again and we'll get here soon. oh yea my fee is 75 an hour, i figure your new bill should be about 300 now, cash check or charge. lololol hahahaha. just a little humor

    Hopefully all of you (anyone I’ve seen on this website so far, talking about ANYTHING subwoofers..) have learned quite a few GOOD, EXPENSIVE AZZ LESSONS! None of you know wtf youre talking about, and.. I’m honestly very highly confused as to what compels someone to answer a question... and they obviously know less than the person who asked it. “Turn gain knob all the way clockwise.” Yeah that’s correct. If you like to cook eggs on your paperweight of a sub once it’s done. While your at it, don’t forget to season em with +12dB @ 20hz Bass Boost!! lmfao.. buncha clowns. ??????????. How about SOMEBODY use a thing called GOOGLE. And ask, Hey Google, how do “I tune my car amplifier, CORRECTLY?” Anyway gain isn’t volume my dudes it’s a voltage matching system for amps+decks/head units (ThE rAdIo!!!)

RF p2d2 12 smoking

you cooked the coil in the sub when you see smoke you have clipped the sub. improper wiring probably the issue ohms must match gain must be set properly . if you had gain all the way up thats what did it.

Why does my 6x9 amp drop or not let the sound play at all when my subs are on? it just started to happen? they worked together fine before. i turn the subs off and the 6x9 work? but when i turn the subs on...

You probably have too much hooked up for the size of your power supply which is presumably a small car battery. You either need to get:

A) New, better bigger battery.
B) Capacitor in series with battery.
C) Both of the above.

2 12 p3d212 2 ohm hooking up to a rockford fosgate p325 .1 mono amplifier can it work? and how?

Hello a_brake11,

The P325.1 is relatively small to power a pair of P3's. You'll only get 325 watts RMS at 2 ohms (162.5 watts per sub). The P3's power range is from 100-500 watts, so they will work, but don't expect them to be really loud.

For best power, your subs should be wired with the voice coils in series and then the 2 subs paralleled to the amp resulting in a 2 ohm load.

Hope this helps.

I have a Rockford PL2-110 and intermittently I get a loud popping noise out of nowhere. the sub sounds good the majority of the time but occasionally it will make the noise more and more often. any ideas?

Have you double checked the wiring ( + to + and - to -)? When hooked up correctly, a sub should push outward when bass hits. If your wiring is correct and your amp isnt too big for the speaker then its about to go out.

Amp power protector comes on

Dis connect the sub then turn it on, don't let the wires touch or it will have a problem. If your lucky, it's just your sub that needs replaced. If not, your amp needs serviced. Rockford use to have a three year warranty... I'm not sure what they have now since mass merchants beat up the line. Hope this helps

Rockford Fosgate P250.2 - No Power

1. no all amps can go bad with a bad installer !
2. repairs sometimes go for as much as it was new! so somettimes not worth it!
3.1 12 4ohm would sound lot better i reccomed mono amps for subs being they only put out low feqz and are better and more battery effient!

Rockford Punch HE2 wiring question.

if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.

Sub hook ups

There's a lot more factors involved than that.
  • Power capability of the subs
  • Type/size of the sub box
  • Allotted space in the vehicle for the sub box
  • Voice coil impedance of the subs versus the capability of the amp
  • Etc.


You may be surprised to learn that even though there is a negative and positive on the sub it usually dont matter all that much because that amp allows you to switch the polarity of its outputs to allow your mids to sound better... anyways on to your question To wire a sub it depends on how many you have, if they are dual or single voice coils, what impediance your amp is stable at. Tell me what type of amp you are hooking this subwoofer up to and how many are being connected. And ill try and give you the best way to connect the sub(s) to your amp.
