subs you used in your truck?

I only said Pioneer subs... The rest of what Pioneer does, is pretty good! I just never really been impressed with their subs...

I would like to figure out how many dB's I hit now, especially since I dynamatted it...

Second that. I used to use there slim subs and I was never really impressed with them.

Remember that when building your system that you need to be able to power these amps and subs. A single battey system no matter what amps your using if you do the calculations can only produce 900 watts. A single 10" or 12" subwoofer system if designed correctly should be able to hit around 140 DB. That should satisfy anyone for just cruising.

When your running a single sub system and want more out of it, before you go out and buy all new shit check message boards and forums to see if you can get it louder by changing the enclosure. I've seen at least a 4db change in different boxes. $30 in MDF is alot cheaper than a new sub and amp. I have never trusted manufactures enclosure specs. There more a basic formula to follow that will be a good size for any box shape (and lots of other variables) and any vehicle.

Thats my 2 cents.

HAHAHA sorry dude but single ten or twelve at 140db? your smokin crack, show me, i have been around stereos a long time and no way bro, also a 4db difference is huge considering every 3db is twice the amount of power... and how are you going to say that a factory spec box isnt up to par, do you think that the factory doesnt know whats best for the speaker they are building?? you do realize that when a speaker shows you the amount of db at 1 volt 1 watt is used in a box specific to their specs given to you.... and thats my dollar

Trial and error. Thats how I base my opinion on this. Like I said, they give you the best airspace for a number of different applications. They don't give you tuned specs. Plus they can't know every different application so they give you the best guideline they can.

I'm not going to knock you opinion and laugh at what you said because I have respect for what you think. I knew that posting my "opinion" would cause controversy. I've done stereo's for about 10 years now and I am not new to the game. In the future I'll keep my "opinions" to myself and not try to help anyone out. Later.

not knocking your opinion just think its far fetched, also dont get sand in your vagina, nobody is saying dont voice your opinion its why the site is here to do so, im not 10 years into the stereo scene but about 5 years and have never seen such a drastic improvement ie:4db by switching out a box. and thats a lot of work to do to a box not knowing if its going to change anything...?? very true you give you the best possible specs on a box size, applications vary yes, but the specs they give you are not universal by any means they are what that speaker is made for, also why some boxes have tuned frequencies because thats what the speaker is designed for,... anyway im out, not tryin to argue just speakin facts as you are.

Having an enclosure in a vehicle is way different than having it in a room perse... You have to play around with your imaging to get the best bass out of the subs inside the vehicle. Optimizing all your factors of things like the enclosure, imaging, sound deadening are things that can be changed outside of the subs capabilities. When you introduce a sub into the vehicle, the vehicle alone gives about a 6 dB increase. Being smart on how you provide power and enclosure, etc. gives you the best bang for your buck!

Eh, you may see some people with a HUGE enclosure for their sub. Inside the port is LONG. This allows that bass note to lengthen out so it all hits inside the truck and not 10-20ft. outside it!

Just a little info.... So 140 dB's is'nt impssible with 1 sub!

You guys need to move to southern California. You can run them as loud as you can stand it. It's not unusual to hear them half a block away with the windows up. Actually you feel them before you hear them!

not sayin hitting 140 is impossible with one sub, but with 1 10" sub thats what i have have a hard time believing, a 10" sub only has so much excursion, and the amount of airspace moved isnt very much.

It's more of an educated guess with doing calculations. In theory it may be better but only "real world" results will tell. More often than not you will always improve but how much is the question.

I know there is quit a bit of subs at 10" that can hit! Maybe not 140 dB's, but pretty close! All without doing any improvements to the manufacturers box specs.

Try an Eclipse titanium pro series woofer, or an Orion H4, a MTX Thunder 9500 or JL W7. Theres plenty more woofers out there like these that have MAD excursion and power handling to get the job done with a 10" sub!

This reminds me of the new line of subs Focal is making. They did'nt look very impressive at all really, but I was mistaken when they put the subs in the high-end room, and come to find, the subs made the glass shake!

The wonders of surface area, excursion and how air is compressed that makes a subsonic wave, is really mind-blowing...
