wiring subs

[mli_699]

I have (2) Lanzar MAX12D's dual voice coil subs @ 4 ohms per coil with a max wattage of 1000 watts @ 2 ohms and 500 watts @ 4 ohms each sub.(4ohm nom. impedance). I plan to connect them to a Lanzar HTG 244 Heritage amp. 2x250W RMS at 4 OHMS. 2x500W Max at 4 OHMS

1x1000W Max at 4 OHMS Bridged. 2x420W RMS at 2 OHMS and 2 Ohm Stereo Stable Operation Bridgeable at 4 Ohms

THD: 90dB

Channel Separation: >65dB

Stereo, Bridge and Tri-Mode System Application Compatible

One of two questions is: how do I wire the subs and the amp to get the most out of them. I saw some diagrams on one of the posts about the Fosgates but it was unclear to me because I only saw one positive and negative lead running from the amp to the subs. Was it a one-channel amp? If it was a two-channel amp, why wasn't leads running from the amp to one sub and then the other? Maybe I need to be explained about how the diagrams are set up. Any help?! I need a diagram that clearly shows how to wire subs with a two-channel amp. My other question is: what are the dimensions for a sealed enclosure per MAX12D. I have to have a sealed enclosure because I don't have much room in the trunk. I have a convertible and my trunk dimensions are: 14"(H)x10"(D)x38"(W), which is pretty small. Do you recommend ports, and if so, what length, diameter, and position(top, side,front). Any help would be appreciated.

i would wire the two subs in series which will bring you to 4 ohms. so that would mean on each sub your going to take a wire from the postive terminal to the negative. that will leave you with two terminals left on each sub, which you would take the two postives left over and take them to the postive channel of the amp, and do the same with the negatives. this will leave you with 2 terminals not being used on the amp, that is because your bridging the amp to get the proper amount of power for your subs.

^^^^ thats how it will look.

a ported enclosure is the better route to go, but either will get the job done. decide which kind of box you want before we can discuss proper dimensions.

Thanks for the reply. I understand the diagram except about the channels. Let me explain. Do I connect to the positive terminal of one channel of the amp, and then the negative terminal of the other channel,(bridging)? About the enclosure. I will probably go with the sealed. Any suggestions on dimensions. By the way, you've been a great help!! Thanks!!

yes.

Any suggestions on dimensions.

hmm....tried searching all over google for the recommended sealed volume for each sub, and the displacement of them, but had no luck. do you have this information?

Unfortunately, I don't. Are my figures right on the amp-to-sub connections??
