Ive had 6 blown subs in the last 6 months

I bought two 10 inch P3 subs, and im powering them with a 600.1 rockford amp. I had them professional installed, and one of the subs kept blowing out. the people at the store kept getting mad at me but, i swore it was not my fault. when it blew again i finally just took things into my own hands. I took the subs out of the box and immeidiatly realized that one of the subs was a 4 ohm. i was so angry i went back to the store to show the men it was not my fault it was theirs, and maybe get my money back after buying the same sub 5 times!! but with my luck the store had gone out of business(i wonder why!). I orderd 2 new 2 ohm p3's of the internet and installed them myself. they are wired properly to my 600.1 amp and i have i very nice brand new pioneer deck. Once the system was finally hooked up correcty, it sounded better than ever! but in just 7 days one of the subs blew out! It just doesn't make sence. each sub handles 400 watts and i only have 300 going to each. Is there some other aspects that could be causing my subs to blow out. or did i just get the one malfunctioning sub when i finally got it right??? please help!

    ok since you have two subs and one amp...what are your RMS watts on the subs and the amp? also how are you wiring them into your amp?

Be careful with fosgate amps. They are more powerful then what is stated on them. I found this out when I blew a 15 with a punch 260ix. These amps are made for competion use. The 600.1 does not push 600 watts as stated. I had one tested and it actually pushes close to 800 watts. Turn ur bass level and ur gain to about 3/4 power and this should solve your problem

I have two 12 inch rockford p1 punches powered by an 800 watt sony explode amp (2 Channel) and i want to install another 15 inch kicker with a 1200 watt amp not sure the model, i got it from a friend and...


I have a similar setup & I just run the second amp straight off the other amp by running positive & remote wires directly from 1 amps positive & remote inputs to the others amps inputs. But my head unit has RCA inputs, (sub in & front & rear inputs) so from my 4 channel amp I run 2 6 inch alpine S's to the front to the front RCA inputs of the head unit, & 2 Pioneer 440w 6x9 inch speakers to the rear inputs. & my 800w 12 inch sub from my 2 channel amp to the sub woofer inputs on the head unit. Has blown my eardrums for nearly 12 months now great stuff! Hope this has helped

Connect rockford fosgate amplifier & speaker together


Assuming your P3 has a single voice coil (it will have only one place to plug your wires into) you will be running this in a bridged mode. You will take the left (+) coming off the amp and plug it into the (+) on the P3. Then take the right (+) from the amp and plug it into the (-) on the P3. This will make your amp push 500 watts to your sub. Now on the amp make sure your adjustments are as follows: Signal input switch is set to unbalanced for RCA input. Left Phase switch is set to 0. Right phase switch is set to 180. your X-card should be set to low pass. And adjust the gain for both R and L equally so it has equal power from both channels.

Same exact problem


Hello phatjay_31,

It's likely that the sub has been damaged by too much power. The Type R's in both 10" and 12" versions can only handle up to 500 watts RMS. The 15" version can handle up to 750 watts. The Rockford-Fosgate T3000bd1 amp puts out 3000 watts RMS into a 1 ohm load.

I'd check the voice coils. They are probably melted.

Hope this helps.

Is it enough to power to 12 volge=ahagen 12oowatss dual 4 ohms


your Volfenhag 12" subs are rated at 1200 watts they are only 600 watts rms and the Rockford punch p4004 is only 200 watts rms so the answer is yes it will work but if you get a amplifier that pushes out 500 - 600 watts rms you will love the sound from subs
there is nothing wrong with the Rockford amp it just wont pound out the bass as hard but the good news is you will never blow the subs with it
when buying amps or subs make sure to look at rms rating that is the true power they actually have ie. (sub box says 1200 watt you think powerful but if you divide it in 1/2 you actually get 600 watts rms) don't get me wrong that's a nice rating. for a sub but you will want to match that number with the amps rms rating or lower. The RMS is what makes the car pound the higher the RMS the better
hope this helps

Subs sound terrible (Ive tried so many things)

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.

Cant figure out my car audio problems!!!!!


There are a couple of tests you can perform. I'd first recommend checking the shield ground. You'll need an ohm meter. The details can be found on the following page.

RCA shield ground test

You can also test the output with the multimeter. Set the multimeter to AC volts. If it's not an auto-ranging meter, set it to a voltage range of ~2v AC. Disconnect the RCA cables from the head unit. Touch one meter probe to the outer ring of the head unit's RCA jack. Touch the other probe to the metal contact in the center of the RCA jack. With the head unit near full volume and a clean signal source, you should read at least one volt on musical peaks. If you have a bass disc or a test tone disc (~60hz sine wave), use those.
