I HAVE A BANDPASS BOX HOOKED UP TO MY KENWOOD WITH A ALPINE AMP MY BOX WAS GOING IN AND OUT THEN I LOST POWER TO MY WHOLE SYSTEM I CHECKED ALL MY FUSES AND THEY ALL LOOK GOOD...CAN ANYONE HELP ME WITH THIS PROBLEM?
Make sure you check all the fuses, this means the fuses on the radio Red and or yellow wire, the ones in your fuse panel, The ones under the hood, (if any) the fuses in or connected to your amp. The best way to do this if you do not have a volt / ohm meter is to buy new fuses of each typ used in your sustem and just swap them out. As you say your whole system is dead including the Head Unit (radio) after replacing the fuses you will need to check to see if all the wires to the radio are still properly connected especially the grounds. If every thing above checks out then you have a dead radio and it will need to be replaced. Again as you say the WHOLE SYSTEM is out I assume you mean the radio as well.

I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!
basically as long as your amp has enough power to run the woofers the system will work but factors such as box type, vehicle, woofer direction, amp tuning, etc. will have more effect on the system as a whole. so here is some basics...
> what kind of vehicle?
> what kind of box (sealed, vented, bandpass, etc.)?
> what kind of music do you listen to (how much rap in percentage of all music you listen to)?
> what head unit, amp, and woofers?
> how much bass are you wanting?
> are you building this system on a budget and if so how much are you expecting to spend?
that mainly depends on the type of music you will be listening to. If you need clean, punchy bass, use a sealed box. For more growl, and louder bass, use a tube ported or slot ported box. I would not recommend a bandpass box for 15"s but they do make them. I have 2 kenwood 12"s in seperate slot ported boxes with a SPL 1500 watt amp, making about 149Db in a 93 Eclipse. Let me know if this helps :)
Did you have it hooked up by a professional or did you (or someone you know) do it. If a shop/pro didnt do it make 100% sure everything is hooked up right. Increase the size of your power wire from your battery to the amp. Check your gain settings on the amp. If the vehicle you have this in has a trunk (not a hatch back), position your speakers against the back seat facing you as your putting them in the trunk. If none of this works, buy bigger speakers and more power!
That amplifier is 900W x 1 @ 2ohms.
If your subs are 4ohm SVC wired Parallel, resulting in a 2 ohm load, each sub will only see 1/2 of the rated power. (450W ea.)
Your gain (sensitivity) setting should be between 75% and 85% to max. You will be fine.
