I recently put my kicker cvr's in my new Jeep and wirered everything the same way i did in my old car, but took out a capacitor i had and wired from the battery straight to the amp. the amp and subs work, but arent very loud and distort easy. when i pull one of the RCA cables out, the one subwoofer that remains plugged in is louder than when both subs are plugged in. and its the same way when i plug them both in again and take the other rca cable out. Help!!!

How I tune:
turn amp all way down or disconnect rcas for now, turn up stereo to a song with some bass you listen to and crank it as loud as you would (not max about 3/4, use this to tune inside speakers (don't have bass maxed/distortion...)). Now dial in amp: turn up a bit probably to 1/4 or so then tune frequency I'd usually say around 100hz, then adjust gain again to where it sounds good...be easy on them for awhile to let them break in (don't blast them all day!). Usually bass boost is only 1 frequency with a curve (40hz or something)...so I try to not use it much....
It's drawing too much current. make sure you have a nice solid ground to your car chasis( i use seat bolt or something like that) and that your wire is the right gauge. If it's still popping your fuse make sure you are wiring the subs as specified by the manufacturer.
Sounds like the amps needing more current available to it-You should have 4 gauge power coming off the battery going into a distribution block from there a 4 gauge to a 1 farad capacitor off the block -4 gauge to the ground for the capacitor -and two + leads from the block to your amps-you would do well with 6 gauge there.- That is to ensure that you have plenty of power on tap when needed and not trying to draw it off your charging system on heavy current demands.Make sure that your grounds are well placed and solidly connected. As for putting 600+watts on a pair of 8z......i hope that they are the CVR or the L5 / L7 series to take that much power,I've seen it done and the ones i heard sounded badass(L7 series)-but that was at the stereo shop so they had they stuff on HITTN status up in there. If your running the "cvr" or the "comp" series you might be throwing too much power on them -might want to step up your subs to a set of 12s just to get more air moving in there- good luck
you've spent alot of money on **** by the sounds of it!!. you should only ever run multiple subs the same brand, power and resistance you can just connect any old subs to a system you need to wire them depending on the load that the amp needs to see. first thing is to try the amp/s on a individual sub to check your amps still work once done check the subs 1 by 1.
Send me your email account and i will draw you a diagram and send it to you there. I will need to know if the ohms of each sub as well as the amp. I'll also need to know if the subs come with one or two voice coils.
kicker subs arnt ment to hit the lowest bass, unless you go spend a **** load of money, im talking 3000 wat amp, ant some 15' or bigger subs. the most commen kickers are 12' subs, so im asuming you have 12' subs, if not, this (said lightly) should work. try turning the bass boost screw on the amp to the middle of its turning range. this will offer the greatest balance between high and low bass. if you want more low bass, turn it past half. if you want more high bass, turn it down. i have mine set to mid range, but i also recently purchased 2 18' kickers. with every new set of subs, you should spend at least 15 min tuning the amp to get the best performance. every sub is different. hope this helps, good luck.
did you set your gains and base boost also when you put sterio back in dash did you put rca's on proper outputs or the rca's could have pulled out when putting back in
you have high output and low output
are your subs getting sound to them at all any current going threw speaker wires to subs
radio settings might not be set to back end for subs this is a feature on most receivers to shut off back end subs
Sounds like you have got almost all the good out of those Subs. You can find the screws you need at almost any hardware store or Auto parts store. The light is becase you are dloading the amp with low OHMS. You may need use one channel and Run the wiring like written blow to get the power problem to disappear.
