amp issues? or headunit settings. i dont know

[majik455]

Hello all, I have a new jvc headunit and had a kicker amp and 2 6 inch base tubes. It worked but never really basey. I recently wanted to "upgrade" so i purchased a 1200 watt mono block sony explode amp and a box with 2 colbolt 10's. I am not getting any thump...and with a 1200 amp i expect it.

amp was new
woofers tested
I even reran the wiring from the head unit to the amp (new rca and remote wire. I ran a 4 gauge wire from battery and tried different grounds.....no boom boom)

its on power wise and only really sounds like someone hit the "loud" button.
I am stumped and frustrated

I have tried different headunit settings but nothing changes BOOM wise.

Help please

1: its a sony xplode, so thats not an rms wattage and most likely was made up to sell things.
2: Did you set the gain and frequency? (To do so put on your best bass beat and crank the volume to what you normally rock out to. There should be a tuning knob for the gain and set that to a good thump that doesn't distort the woofers. Frequency is a little more tricky to set but you can fiddle with it to get what you want. Look at the response curve and set from there.)

Yea, as stated, that is max power for the amp. A Sony Xplod 1200w mono is only rated at 600w RMS into a 2ohm load (lucky if you even get that). At 4 ohms it is only 300w RMS. These ratings are also only good if the amp's gain is pretty much cranked all the way up, which just makes it sound like crap anyway. It doesn't help those subs are only rated at 400W RMS (Orion Cobolts right?) max either, there's no way you're really going to get a lot of boom out of em.

So really, if you have those subs wired parallel into 2ohm on that amp, you're actually overpowering them going by the Sony specs. Although if you have them in series, on an 8ohm load, they're actually going to be a bit underpowered.

well I wouldn't say that. 400 watts rms with <1% distortion is a lot of power for car audio. Even more so in a truck cab as its so damn tiny. The issue is when you get brands like xplode they blatantly lie about the specs so it makes the wattage number almost irrelevant.
