Greggs Unregistered guest | i have 2 12 inch p3's... 500 rms each... ihave them connected at 1 ohm to a audiobahn amp... 1200 rms at 1 ohm... i have in a sealed 3/4 inch mdf sealed box... just wondering if i got a ported box would make it louder?? i had a crappier system and it seems like i felt that system vibrate my car more.... it was a port box but too small for my p3's that's why i went to sealed... if you could help thanks... need more info just tell me.. |

IMO - porting could improve it temp until u buy an amp |

Greggs Unregistered guest | i'm going to stay with the amp.. don't want to spend much more money... like would the ported make my car vibrate that much more than a sealed?? what kind of prices you think would the ported be??? |
|
Greggs Unregistered guest | i was also wondering... i have a capacitor that reads 12.7... when the subs hit hard it jumps down to 11.5 or so.. and the head lights dim .. i got it so the lights wouldn't... i got the battery checked and it is in "good" condition they said.. so i'm wondering if i should just buy a battery that is stronger??? is that a possibility for not as loud as i thought they would be?? if so.. what kind of battery do you recommend...?? run 2 batteries?? if so .. how to hook them up?? thanks |

Everything vibrates in the car now with the new box. For the cost wise, it could only cost you $50 or so if you knew how to do it your self. All you need is 3/4" or 1" MDF board, glue, screws, caulking, etc. |

Greggs Unregistered guest | so if i have all that.. how do i go making it ported??? i'm not real good with boxes at all so take it easy... like right now i have 3/4 mdf box sealed... like if i put holes in that it would be technically ported... but i don't think it would sound better....?? i might just go buy one for 70 bucks done customed..?? |

Post Number: 2026 Registered: Jul-05 | that would be extremely hard to replicate cause i'm guessing that u did not see a cutaway of that box - it has internal chambers . $150 is not bad @ at all considering its a new(?) factory made box . Google or ebay & u might find it cheaper ............ |
