Hey all,
I was hoping to get some advice on how to tune/tweak my amp for maximum response in my subs. I am running a JBL GTO14001-Z amplifier (1500W RMS). I have 2 Rockford Fosgate Power HX2 subwoofers wired seperatly tot he amp. I installed it about a week ago and I cant tune/tweak the amp for nothing. It has 4 knobs you can tune/tweak with. #1:input level #2:LP Freq #3:HP Freq and #4:Boost.
All of this is foriegn to me. i use to run a old rockford amp that only had a boost kob on it. so asking for help may make me seem like a douche but i have no where else to turn to. SO i thought id ask the experts for some advice.
so heres the specs of my "sound system"
Deck: Panasonic CQ-C9801W
Front Door Speakers: Rockford Fanatic X Component 6.5" Speakers FNX-2614
Rear Door Speakers: Rockford P1653 6.5" 3 Way Speakers
Subwoofers: 2 Rockford Power HX2 RFR-3112 2000W max 1000W min
Amp:JBL GTO14001-Z amplifier 1500W RMS
Capacitor: Tsunami 10 Farad Cap
Each subwoofer is in a 2.75ft sealed 3/4" MDF wood boxes. I am seriously thinking about porting the boxes but i dont know yet.
basically my question is this...
what do i set the input level, Lp Freq, HP Freq, and bass boost of the JBL amp to to get the best possible bass from my 2 rockfords? Ive tried many different combos and nada works right. it will sound good a low volumes but when i turn it up it just sounds crappy. again im a novice just asking for some advice.
also if i were to port my sub boxes what should i set each knob on the amp to.
the rockford power HX2 manual says that (2) 4" wide x 12.65" long ports are needed to get true spl from the subs.
also my deck has a Lp Freq and a HP Freq adjustments on it. the Lp goes from 160Hz down to 0Hz and the HP Freq starts at 90Hz and goes up to 200Hz.
any advice-guidance would be greatly apreciated because i dont know what the heck im supposed to do. thanx
