I have a kicker sx650 powering two kicker cvr 102 at 2ohms but i havve no clue on where to set the settings at and i know this amp should make these subs pound. i need to know exactly what to put each...


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....

Sony how to change the bass on my sony mex bt3100u stereo


Hello Tom,

You may have to adjust the EQ7 Preset to XPLOD and then listen to the jam. Here are the instructions from the bt3100u manual:

Selecting the sound quality
- EQ7 Preset
You can select an equalizer curve from 7 equalizer curves ("XPLOD," "VOCAL," "EDGE," "CRUISE," "SPACE," "GRAVITY," "CUSTOM" or "OFF").
1 During reception/playback, press the select button.
2 Rotate the control dial until "EQ7 PRESET" appears, then press it.
3 Rotate the control dial until the desired equalizer curve appears, then press it.
4 Press (BACK).
The display returns to normal reception/play mode. To cancel the equalizer curve, repeat the first 2 steps then select "OFF" in step 3.
Tip
The equalizer curve setting can be memorized for each source.
We hope that this helps. If not please return and post how this went.

some amps are made more for low ohm loads (bass) and some are made for high impedence loads (mids/highs) and it seems you are asking too much from your amp.

How new is the amp?

A single faulty solder can do that...I'd try returning in to the seller.
Have you tried a different amp with the same equipment?

Sounds like a wiring issue.

Hope I've helped

Because even though your stereo is turned down the gain for the sub is set all the way up so it will still gain a small amount of signal. it is a flaw with some of the newer aftermarket stereos. try turning the nob until the thump stops then change the bass setting on your deck to compensate for the bass loss.

Set your equalizer to you a V shape or U shape pattern, bass effect can only attain by adding a powered subwoofer, (amplifier and subwoofer). subwoofer without an amplifier doesn't sound good, your system doesn't have enough power to drive your subwoofer.

Stock Stereo Bass automatically goes up


the button is stuck for the bass, this is common to happen, you may have to replace the stereo.

No bass


There's a small switch on the side labeled LP-AP-HP. Make sure it's in the LP or AP position, not HP. There's a small dial labeled FREQ; if your amp is connected to subwoofers and the switch is in the LP position, adjust the dial until it's set around 80-100.
