I have a Hifonics XXV Colossous and 2 JL 500/1's. I want to know which I should use to push my 2 12" W7's to get my full money's worth and the best of the subs. Also if someone can describe how I should...

i highly recomend you use the hifonics colossous and wire the subs @ 2 ohms and you would be right about nominal power handling for the W7 which is rated @ 1000W, and your amp would push about 1100W to it. just be carefull when adjusting. and the best advice i can give you on the settings is as follows: Turn up the volume to the desired listening average level. (what you would normally have it on when driving) then adjust your amp by turning the different controls up, and then back down a 1/4 turn after distortion occurs. in your case with so much power dont turn them up all the way right away ease into it be gradual listen to the change in the sound.

Hifonics BXI 1606D problems

it may be a wiring problem you need to make sure all the speaker positives and negatives are correct. I sell alot of hifonics amps and have never had 1 do that. it may also be a bad rca cable. if it only does it when you use the filter i would say not to use it also make sure the gain is no more than 3/4 turned up and the bass boost no more than 1/2. if you have a dif amp try a temp setup using it and if it still does it its a wiring issue. also try 1 speaker at a time on the hifonics and keep adding 1 till it comes back it may be a bad voice coil on 1 sub .

No sound in my Hifonics Brutus BXi 1206D amp

Have you confirmed that you have a good signal feeding the amp?

Have you confirmed that the speakers are in good working order and don't have any breaks in the wiring?

Amp does not work

make sure your power and ground wires are 4 gauge thats a big power puller also make sure your wires to woofers are correct!and you want a short ground wire and a good spot for it no paint!!
if there out of phase that will shut it off BUT you might be needing a battery cap. MORE POWER!!!!they dont cost much
and save your battery and alt.hifonics is a good choice my favorite are the series 7 they dont make them like that anymore!
hope this helps one more thing your many amps is it?
my honda is only 60 amps your brutus pulls that all day !
(BATT.CAP.or HAVE ALT.WRAPED for more power.

Interior speakers cut out when the volume is turned up

You may have speakers of an incorrect impedance attached to the unit since the problem occurs when audio signal level is increased and the current goes up.The unit is shutting down to prevent damage. I would check the speaker connections and make sure that the speakers impedance are matched for the unit you are using.
