ok so i have two kicker cvrs and a rockford 325.1 amp. would it be better to install one to the amp or two? im planning on building my own ported box for my hatch.

 

Can you put up a link for the subs you have and thier voice coil config.

 

there just like these except that the ones i have are 12'

You can useboth of them. I personally just use a single sub. Just make sure you build the box to specs.

 

well each one is rated at 400w rms and the amp is rated at 375 rms. would it still sound good?

 

If your going for SQ, I would use both subs in a sealed enclosure around 1 cube per sub.

If you want something loud that will sound ok with music, Build youself a ported enclouse tuned to around 30hz. That will play nice and low, overcome the weak amp with the increased volume from the port, and still provide some sound quality.

I would contact kicker and ask them what there SQL box dimensions are and optimum tuning frequency.

 

what if i want it to sound really loud? should i go with one or two?

 

Use both in a ported box. You could use an ABC box but thats a little to complicated

 

alright thanks for the help i think i'll build the box tomorrow for two and see how it sounds. how big does the port have to be and where should it be for the best sound?

 

THere are two different port styles to use. Rectagular and circular. The easiest thing to do would be to design the enclosure to put a circular prot in between the subs and slightly offset. 3 inch pvc pipe is a great port making material, plus you can get a hole saw that will cut just about a perfect circle.

I will build a box tonight to play with my $10 visonik sub and will take pictures of the progress.
