I have 2 kicker CompVT 2ohms in a shallow box, I am borrowing a amp and with both it is under amped and sounds terrible but even if it connect it to one it still sounds horrible.

SOURCE: No Power light or sound from kicker amp and speakers

OPEN UP THE AMP AND CHECK THE FUSE HOLDER THAT IT IS CONNECTED TO THE BOARD
IT MAY HAVE GOT BUMPED AND THE CONNECTION MAY HAVE BROKE IT MAY BE A HAIR LINE BREAK WITH THE COVER OFF AND THE POWER ON MOVE THE HOLDER MAY NEED TO BE RESOLDER THE CONNECTON THATS ALL IT IS GOOD LUCK

SOURCE: bass sounds muddy and volume is minimum.

Hello mercedesman4,

Your setup sounds great. I had to settle for Blaupunkt in my Mercedes.

It sounds like the culprit is your enclosure. It's possible that by tweaking the settings, you could improve the sound somewhat, but having been used to the sound of a sealed enclosure, maybe not. Sealed enclosures tend to produce tighter, more accurate bass and have a flatter frequency response curve. They are also generally the enclosure of choice when looking for a SQ (sound quality) oriented setup.

Ported enclosures will produce louder bass than sealed enclosures, and maybe that's why some audio guys push them. They also allow the speaker to operate more efficiently, so you need less amp power for a given volume. Higher tuning on a ported box will get louder, but at the expense of sound quality. Lower tuning will still get louder than a sealed box, and the sound quality will be better than a box tuned higher, but still not as good as sealed. That's what I meant about tweaking the settings. You may see some improvement by setting the crossover lower, decreasing bass boost, or by turning the subsonic filter on/off. I'm no audiophile, but personally I've never been able to stand the sound of a ported enclosure, however it was tuned. Sealed just sounds better.

Hope this helps.

SOURCE: i think ma kicker kx1200.1 amp is blown or ma kicker L7 are gone

that would be the amp. sorry to say. when a wire crosses over, it sends a shock through the amp, there are a few things to try just to see if you fried the amp. the first thing to try is to move your ground to a different location. second thing to look at would be the fuses. alot of times the fuses will blow at the slightest shock. the amp will still turn on if you have an amp with 2 fuses, it just wont be getting all the power it needs, which could be causing your problem. also, it is worth the hour and a half to mount everything down in your vehicle. you might check the kicker website, because i have herd rumors that kicker offers a lifetime warranty on almost all of their products. best of luck, and i hope you didnt fry your amp.

Hello juan_penaloz,

The Kicker L7 has an RMS power range of from 50-750 watts and a maximum power handling capability of 1,500 watts so your Sony amp will power it OK. A more powerful monoblock like the Alpine MRP-M1000 or the Kicker 08ZX750.1 would provide even more power and could operate safely at 2ohms.

You have the voice coils wired properly for the Sony amp. It's OK to have the sub impedance higher, but you definitely do not want it lower than the 4ohms the amp is rated at in bridged mode.

Hope this helps.

SOURCE: Overheating amp problem...easially fixed, i think....

depends on the sub rating.

if subs are 2 ohm rated you can ONLY get 1 or 4 ohms..
2x2=4ohm series
2/2=1ohm parallel

if subs are 4 ohm rated wire in parallel
4/2=2ohm

look it up google for diagram if you need one.
