I recently have hooked up 2 15w3 jl audio woofers. I have a Hifonics Brutus 25th addition amp 1200w it pushes out 450@ 4 ohms which isn't the max of these speakers i know but they just arent hitting clear. i don't know how to tune it if someone can help it would be appreciated.

to compensate for the low power...build a bigger box
or keep your box...and get 1k going to each sub...they will love u for it

80

its not a power issue. they are 550rms top speakers. jl's bang for a low ratting. i have a box costume made for these woofers. i know its just a problem with the amp settings. i know i need a better amp one day soon but, i also know enough about systems to know these woofers should be banging regardless if im maxing them out. just wondering if anyone around knows jl"s and could help.

sounds like the subs are out of phase, or you have the vc's wired wrong. I'm not sure of this, but it looks like they come in dual 2, leaving you with either a 2 or a .5 ohm load. make sure that your gain isnt maxxed out, your bass boost is all the way down, and your low pass filter is set to about 80 hz.

Make sure your subs are wired up right and not out of phase as said before. Use this link to verfiy your wiring.
JL Audio
(this is if you have the JL audio W3 version 1 or Version 2 only which have dual voice coils.)

JL Audio
(this is for the single voice coil W3v3 only.)

you can tell if you have them wired up in phase, by taking a 9-volt battery and putting the + speaker wire on the + of the battery, and the - Speaker wire on the - of the battery. Both speakers should pop out towards you. If one moves one direction and one moves another, they are out of phase. If both move in, when you have the positive and negative matched up with what's on the battery, then the are reversed phase (also out of phase).

Now read how to set your gains on your amp.
JL Audio

Or in dummy terms, just turn the gains on the amp about 3/4th the way up, bass boost should be no more than 1/4 to 2/4 the way up. Make sure the RCA output from the deck is connected to the non-fader (subwoofer) output. Also make sure the crossover switch on the amp is set to Low Pass. If it lets you adjust the frequency range for low pass, set it to play about 80 Hz and down. Your amp manual should tell you how to do this.

Hope this helps, if not, you will just be better off taking it to a shop and letting them do it for you.

Also make sure your subs are wired in the right ohm load for your amp. Wire it too low, and the amp will blow or not perform right. That's about all I can say.
