i got 2 diamond subs and 2 mtx subs all four are 10 inchs and i have a standard cab truck would it sound bad to add all 4 because they are different brands? id rather have them in my truck then sitting in my garage thanks

 

Depends on the rms range. If they are similar ranges, like 400watts rms for 2 of them and 450 rms for the other 2, you'll be ok. The other factor is gonna lie in the amp/s you use, and how the subs are wired in ohms. IMO, I would just put the 2 better subs in, because you probably wouldn't have the needed airspace to run them effeciently, and you'll eventually burn the voicecoils from constant overheating.

 

well said Rip ^^^^^^^ more aint always better either when it comes to audio. I have had 10-10's in a rig then went to 4-15's and now it is going to be done with 4-8's and focusing on sound quality rather than rattling the pictures off the neighbors walls and cracking the fiberglass top on the truck (back in 95). plus trying to push that much gets expensive in the amp, battery, alternator dept. but it was fun! LOL

 

actually if they are all the same ohm you can run them together and running them sealed you will have enough airspace.....the main thing is to no turn your gain up to high on your amp.....but check the ohms and then you can configure your resistence(ohms) and match that to the lowest impendence that your amp will go to

 

Thats what I was going to say megaboom. I think you would be better off running two amps, on to run each set of subs. 4 subs are going to need lots of power, and too little power is very hard on subs. Also getting the correct ohms is going to be tuff with 4 subs. Do you know what there ohm ratings are? Do they have dual voice coils?

 

I'm saying what I know from experience. I had a 05 1500 4x4 standard cab with 4 12"s, had them sealed and good airspace, ran 1200 watts to them, then I went to a ported 2 12" setup.With 750watts the 2 12s outperformed on the lows and mids, but couldn't push out the highs like a sealed enclosure. From the looks of it you want some heavy bass. I live by ported boxes, they do very well on 10s and 12s, and straight shake the truck with a 15.

 

cool thanks guys the mtxs i have the box i can look at the ohms and stuff tomarrow but as far as the diamonds i got them from a buddy and im not sure what they are ill have to do some researching maybe but thanks guys i appreciate it i planned on running 2 amps i have 2........ but once again not sure what the watts and everything is
