i am looking a getting a sub for our boat and my first question is everytime i see a sub like installed somewhere its like turned backwards why is that? and then i have a question about the RMS watts. is that like what you should power it with or ive heard that is like the efficiency of the speaker? then i have some like poll type things. <BR> <BR>what would you say the medium to high end sensitivity dbs: <BR> <BR>this ones about amps. <BR>are fans good: <BR>what is a crossover <BR> <BR>sorry im stupid just got interested in them after listening to one of my friends.

There are no stupid q's... <BR> <BR>Most of us point the sub toward the boat occupants, since subs are very often in the front of the boat this means they point backwards. <BR> <BR>Fans are just another means to cool amplifiers required to keep the electronics within thier operating temperature range. <BR> <BR>A crossover seperate the high frequencies from the low frequencies so you can send them to thier respective speakers. Crossovers are also called filters, chokes, coils, caps.

k so if i was to hook up a 2 channel amp to 2 subs then does the freq response come into play and could i do it would it sound good

Two 2 ohm subs, hook one to each channel, cross them over somewhere between 100-200hz, whatever sounds best to you in that range.

John - Sensitivity is the efficiency of the speaker, the higher the db the more efficient it is. A 90 db speaker will req roughly 2x the power to play as loud as a 92db speaker. RMS is the true way to gauge power output. A speaker rated @ 100rms will play best when attached to an amp rated for >100 rms power

is 100hz-200hz good deep bass

How do you drop Ohms?

depoint, <BR> <BR>I'm too lazy to post all the possible combinations, send me your speaker/amp specs and I'll make a recommendation. <BR> <BR><a href="mailto:mikeskiw@gmail.com">mikeskiw@gmail.co m</a>
