[DD-1 signal/1khz/40hz leds won't illuminate]

So, with the dd1 I get nothing but a power light and a distortion light when setting my gain, the volume is at 45 where I could here it distort at 47, so I just backed it down a couple. Only did this because I tried to see where my h/u distorts at (DEH-8600BH) but got nothing, no lights or anything, through the amp and with trying it through the RCA's. I didn't want to make a long title, but I'm also having problems with my cc1 where I get a power light and a red signal light (green is good) even with the volume at 0. These both being hooked up to (+) and amp ground. Need some help here, thanks in advance.

For under the hood or what?

iirc the XP series batteries are not meant for starting batteries under the hood due to heat related issues and are meant to be used as supplemental battery.

You would want to look at the D series, and your best bet would be a d3400 which fits the factory location perfect iirc.

You could also use a S series battery too which is almost identical to the D series.

For my primary, but thanks man

Would the XP950 be too small for my 2004 Tahoe? I can't find anything for my question anywhere so I thought I'd try on here.
