Getting ready for the summer, so Im building me a new box. Always used a sealed box. Now do I have to use the center divider in the box or can I leave out. I'll be using 2 15's dont know what kind yet still looking. And how do you run two amps together or can that be done. Last ? has anybody ever heard of an amp called Massive is say 150 on it. It's about 24in long and 10in wide and weighs about 10-20 pounds and all chrome.

The purpose of a center divider in a sub box is usually for two reasons. 1.)To make sure each driver has the correct air volume behind it. 2.)To greatly stiffen the enclosure. This is more important than #1 because of the tremendous pressure build-up in a sealed box enclosure. Find the recommended volume(usually in cu. ft.)and build an enclosure that has it. Always add about 20% to the internal volume to counter the amount taken up by the driver basket/magnet.

With regards to the amp, don't be fooled by a pretty face. Do your research and buy an amp that has good reliability and sound quality. There is a lot of cheap, Chinese junk on the market. Caveat emptor.

your subs spec sheet should tell you exactly how much room eash woofer takes up. you definatly need a quality amp it makes all the difference.

Many years ago a buddy of mine had a truck with 2 Sound Stream 10 inch subs in it. They shared a common air space and sounded very good. Unfortunatly one of the subs would eventually blow and then you have one sub working in a space twice as big as it is supposed to, along with a "spring" (the blown speaker) that changes the volume of the box. Needless to say the one working sub would stop working and blow in a short amount of time. After 3 sets, the stereo shop put a divider between the subs and he never had a problem.

Personally I prefer to use a divider because of the info above, and also for the fact that not all speakers are the same strength. When I say strength, I am refering to the magnet and the electronic strength created by the amp for the magnet if that makes any sense. Kind of like your right arm being stronger than your left arm because you happen to be right handed. If each speaker is in thier own enclosure, you can be sure the speaker un affected by anything else, but in a shared enclosure each speaker is dependant on the companion speaker.

Make any sense??

i suppose by running 2 amps together you mean one for each sub.. no problem, you can run splitters from your rcs's or if you have a deck with 2 rear outputs your set.

When I said run two amps together I meant hook them togethter, like two 500 amps and make it = 1000 but reading your comment it make sence to hook one amp to each speaker. (Gotta start using my head).
