Alright so i'm thinking of running 3 12'' subs behind my seats cause thats all you can pretty much fit back there ofcourse it will be in a custom box. I was wondering what kind of amp i'll have to buy.


I'm thinking of running 3'' pioneer premier 1500 watt sub. Now idk to get 4 ohm or 2 ohm subs and what amp....

I have 1 pioneer shallow mount with a kenwood 1000 watt mono amp and it worked good. Setting up 3 is a different story.

Doing 3 subs is pretty stupid, because there is no good way to wire them for being effective on most amps. You're either gonna be above or below recommended impedance, with the exception of dual 6 ohm subs which are far and few.

Even so, if you're looking at a 1500 watt Pioneer, it's probably 1500 peak, so 500 RMS and your Kenwood amp may be 1000 watts peak, who also has a habit of rating peak at 3x RMS power on some things. Either way, it would seem you don't have enough power for 3 subs, you have power for 1.

Just get a good one ohm stable amp and a pair of 4 ohm dvc subs. Don't mess around with patching a system together like that. Plan it out from scratch and buy your stuff that way. And I'm sure that everyone here will be more than happy to help you select equipment.

why not 2 rockford p3 shallow 12s with a t500-1bd?

You can get a WHOLE lot more amp for that much. An audioque 750 is one ohm stable and much better Power and for an extra 50 you can get the AQ1200. And Memphis shallows are supposed to be the best. I have a pair of the 10's and I love em.

Alright so i'm bring this thread back. Since i've already had the pioneer i've been looking at different subs. I hear the memphis 12'' shallow mounts are good?

If I get two of them. They are rated at 500 watts RMS each @ 4 ohms. If I run two whats a good amp to run both? It also says it only requires .45^3.. is that right? It almost doesn't seem like enough.


Or in your guy's opinion as far as best shallow mount. Whats good and whats not.

My experiences with the memphis s class is like this don't over power them, make your box a little bigger than needed, don't play them hard for long, and give them time to break-in.

Pretty much spot on

That box may be fine because the suspension is so soft and it has very little throw. You can get them in single 4 ohm or dual 4 ohm, so that will determine what amp you need.

Break-in is total bullshit. It doesn't matter if you stretch the spiders in 30 seconds or 30 years, the result is the same. If you can't play them hard for long, why not get a different sub? That doesn't sound too reliable.

To the OP, I'll stand by saying you'll sound better and be louder with a pair of 10's that aren't "shallow mount". More actual displacement, more motor force, take more abuse.

Damn idk I like the deep sound of 12's. I listen to a lot of hip hop rap. I dont know if 10's get that low. I want to build another box like the one I had for my 12'' pioneer it was perfect for obs reg cabs. I put the bench seat all the way back and didnt lose any leg room.

I just measured it right now. It was about 4'' at the top and about 6 1/2 at the bottom. I probably could of made it a lot thinner for the pioneer but for the airspace it needed maybe a little longer. with those measurements 4'' top/6.5 bottom 13.5'' high/30'' long.

12's "sound deep" just like 8's "don't play low". That simply isn't the case. How low something plays has everything to do with the drivers ability in itself and the enclosure it's in. Size is irrelevant.

Those dimensions are good for around 0.7 cu. ft. using 3/4" wood. That's a box for a 10.

Well ya that was the recommmended space for the 12'' pioneer shallow... Sounded good.

For some reason I still want 12's. I'm hearing also the P3 from rockford arent bad?

I know you guys are answering a bunch of questions i'm just a noob at audio.

Your not listening shallow mount subs suck. Your dick will not get any bigger because you have 12s. Get two decent 10s and you will sound wayyy better.

Eeeeeeeeexactly. Hell, get some decent 8's and sound better!

ibanender, the driver obviously plays a role in the capabilities of the sub but to say the diameter does not effect the frequency? Not true at all. The best 8" sub can not produce the same frequencies as the best 12"...it's physics.

could you run 3 jltw5's? since their a 3 ohm sub?

Then you need to go back to school. Since you're the expert, you explain to me WHY the 8 can't produce the same frequencies as the 12. Details are required, not general statements.

You could, but why would you? That's an aweful lot of money spent for the outcome you get.
