ok i have two 1100 watt sony explode subs in my truck. i put in a 600 watt two channel rockford fosgate amp. but im just surprised at how little these things hit. is there something else i need to do?? i have heard that the input wires and speaker wires have a lot to do with it. my wires are pretty small. any input would be appreciated.

 

Bridge your wires to your amp. You say its 2 cahnnel, so theres 4 ports, 2 possitve and 2 negative, To bridge them put the nevative on the negative side for one of the channels, and the possitive on the other possitive side of the other channel. if that makes any sense. and for that wattage and sub, id be using either 10 or 8 gauge wiring for the sub. for the amp id use 6-4 gauge for the power and ground.

 

Before you go bridging your amp, tell us the specs on the stuff you have.

Impendance of the subs and voice coil configuration
2ohm, 4 ohm, Dual voice coil, single voice coil, and RMS power rating.

Also, on your amp, rms power ratings at 4 ohm and 2ohm in 2 channel and bridged at 4 ohm (and if it does 2 ohm bridged, most lower end ones do not).

Then i can help you wire it up correctly.

Cheers!

the subs are 4 ohm dual voice coil. and i think the rms is like 600. and i have no idea on the amp cus it was given to me by a friend. i already bridged it and it sounds a little better but i think i just need thicker wiring.

 

i would run 12ga speaker wire also what type of box are you using that will make a big difference

 

also depending on how you wire them will help to http://www.rockfordfosgate.com/rftec...2&woofer_imp=4

 

Wel, you want to run the voice coils in series, and the subs in parallel to each other, to present a 4 ohm load.

Also, power wire from the battery should be atleast 8 gauge, hopefully 4, and speaker wire should be 12 or 14 gauge ( smaller the number the better).
Also, does your deck have adjustable subwoofer gains? (what model is it)

Greg

 

the power and the ground are both 8 guage. i have the 2004 or 5 pioneer premier deck. the amp has gains but i have no clue how to mess with that stuff. but the speakers run off 18 guage

 

Well, you can probably adjust the sub output on your deck to adjust teh dB + or - 12 dB.... Also, adjust the gain knob to where the sub sounds best.... if it starts to distort back it off a bit...
I tune by cranking the speakers to just where they distort then back it off a bit, crank the gains on the deck for the sub, then slowly turn up the gains on the amp until it distorts then back it off a little bit. You cant get any more bass than that....

 

yea, ur gonna wanna turn up ur db buttons for more power from the amp, and the gain is just what u want the subs to cover. if u have 2 explodes runnin off of a 600 watt amp u might b a little underpowered. im sure if u ran just one of those subs of ur amp it would pound strong as long as u had the settings right. u might wanna mess with settings on ur head unit too.

 

something is prolly not hooked up right...get a buddy who knows what they are doing to look at it

 

Sounds like you need to do one of the following:
1. Adjust audio settings on Deck
2. Adjust gain setting on Amplifer
3. Adjust Crossover on Amplifer
4. You need an external electonic Crossover

That's a lot of power going into them subs. I bet you just don't have the correct frequencies going to the subs. The frequencies are controlled by a crossover. I'd recommend a Low Pass Filter with a cutoff of 80Hz and -12db. I'd go electonic not passive when it comes to crossovers.

 

wow huge difference! i put in 12 ga speaker wire. 8 ga power and ground wire. and i adjusted the gain and crossover. then i bridged it and it sounds way freaken good now. thanks alot guys.
