Skar sk1500.1 new amp problem please help!!

Hi all,

current setup: car bmw 2003 520i : standard idrive with ppi soundprocessor, morel 4" front helix 4" rear, diamond 600.4, diamond 1000.1 / skar sk1500.1 sundown 12zv3 dual 2ohm. box as suggested by sundown.

I recently purchased a Skar Sk 1500.1 as they had a (20% off weekend deal) from sonicxxx and a sundown audio zv3 12" dual 2 ohm. An upgarde from diamond audio 1000.1 and diamond 12" d6 sub.

The subs arrive first so I literally just took the diamond sub out with everything untouched, sounded ok but the amp was heating up so quickly that I got scared of frying it, so I went on to and got a sk1500.1 thinking this would do the job just fine and it's less expensive than the sundown saz1500. anyhow once I got it I just switched the amps and this is what happen:

Green light on, low crossover set at 85hz, 0 bass boost, phase 0, wires are 4 gauge ( my car is 2003 bmw 520i so the batteries at the back of the trunk very short distance for pos and ground), polarity is correct wired into 1ohm. all wires are fine either connect or disconnect from skar to diamond amp.

so in goes the new amp: hardly any bump with the gain set to 1/2 about 3v, so i turn it up more to 3/4 which is about 1v still not much bass coming from the subs. I have tried to tune it with multi meter 39v (sqaure root of 1500) with bass tone 50hz but the output seems halved or even less, not much bump coming from the woofer at all (mind you the diamond amps voltage was set only to approximately 2v or 3/5 gain) and it was significantly loud as hell as I switched it back now again and again.

I was going to send it back to sonicxxxx but I'm not in the states so its going to cost me a lot more to send it backwards and forth.

I'm just wondering would it be an amp problem somewhere, or is it normal to have the gain turned all the way up with skar amps cause frankly I've never done that, I never used the remote on all my past system, does it need to be connected or access from there? I mean if there was a wire problem (power or ground) it should have equal affect on the diamond amp as well but not that I can see except the fact it sounds much more powerful than the skar amp.

I've been exploring the amps for days now and i'm just both pissed and annoyed with this problem could anyone please suggest what I can do or test or whatever setting I should be aware of or I'm just unlucky with a defect amp.

many thanks

simon

The Skar Audio 1500.1 amplifier is not CEA Compliant, therefore there is nothing to guarantee that the amplifer put out the published power rating. It sounds like you know how to install equipment. It might be an inferior product.

Skar has a well known product witch is also known to be proven. Not only from customers but by amp dyno. OP Did you try master/slave switch?

Are you using the Gain knob at all? Are you setting the amp with or without the Knob?

If you are, try setting the gain with the knob unplugged.
