Hello,

I have a 2014 ford mustang and 4 Rockford Fosgate p3 in a custom box. I had them being pushed by a rockford fosgate t1500 but like any other bass junkie i have to go bigger so I purchased a rockford fosgate t2500 amp and was wanting to know if this amp will be too much for my subs. I eventually want to replace the subs with something else but not right now. Any help would be much appreciated thanks !

If it was mine I'd go for it.

It's gonna be up to you to know your equipment and set your signal and filters up correctly, when to back-off and let it rest a bit 

But if the box can support the added power and not limit output

I'd go for it... but they're not mine to burn-up... I'm generally vigilant and know my equipments limits, are you?

Those T2500's do pretty decent power so have fun.

I'd like to see a pic of the install, Mustang trunks sure are smallish...

Got a pic or 2 to post-up?

Sealed or ported enclosure?

Going from 1500 to 2500= less than 3 db output so barely noticeable.

+3 db is doubling the sound intensity. +10 db is doubling the perceived volume, so +3 db will make it mar funnerer. In short, if you already got the amp and proper electrical, DOOOOOEEEEEETTTTTTT!!!!

That's why I asked for pics of the install... I'm suspecting sealed
To put it into perspective, this is what 4.2cf looks like in a 17 Mustang. 32wide 13 tall 24 deep, turned sideways 90 degrees. Has to be loaded into the trunk via the back seats, height and depth are maxed as far as getting it in the car goes, You might be able to add an inch or 2 on the width but that's it.

Thank you all for your replys! Here is the only picture I have for now. Until tomorrow the box is ported. I like all your input I like to believe I know my equipment and when things get hot. I'll be able to hear it tomorrow night. My electrical system now is 3 Optima batteries high output alternator and the big 3 I hope that will be good enough to feed this amp. I'll post another pic tomorrow and let yall know how it sounds.

How does that even sound good? Ports toward the bottom section of the trunk and not fired into the cabin thru the rear deck. Correct me if I'm wrong but doing it this way is best for trunk cars.

Actually you're wrong. Sub and port to the rear or to the side is usually best in a trunk. 

Port firing through the rear deck is a common misconception for trunk cars. It most leads to cancellation. 

His box is not ideal because the ports look too small and most likely the airspace is too small for the cone area. 

It might be better to side fire the subs and fire the port to the rear. I've seen/heard that orientation in a 2dr Grand Am and it worked well.

Thx for posting pics Op... if it sounds good then thats all that matters.

Port area looks small for 4 10's but pics can be deceiving. 

As long as you think the amp swap will be fine... go for it 

Kinda looks offhand that the box will limit output to me tho... idk

Mustang neon? Cool.

However I agree with the above said.  Firing the woofers up aint helping much there.  However if it is all you have to work with for now, just roll with it.  

I owned a 2000 for a while.  V6 standard trim. 5 Speed.  The trunk on that one was surprisingly deep for as small an opening that the lid had. Not much cabin space to work with either I imagine...

perhaps your right. I had a trunk car looong time ago, think it was an 87-88 Cavalier and I had a single 15 in the trunk, ported enclosure. I could not figure out for the life of me why I couldn't get any bass at the time. So I drove to a car audio shop to see if they could help. Their suggestion was remove the rear deck speakers so the bass will allow in the rear deck and into the cabin. Made a world of difference. This was prob back in '98-'99 or so...way before the internet was around so I couldn't just hop onto a forum and ask lol.

Removing the rear speakers works when the rear seats don't fold down. It's very hard to pressurize the cabin when the rear seats don't fold and there aren't openings to vent the air from the trunk into the cabin.

That picture makes the port look a little smaller then it really is.

I have to work with the room I have and it isnt much with a mustang sadly. But I made things work the best I can. This is a better pick of the port size.
