*Update I went and got a second opinion and he said something wasn’t right as well. Long story short the 1000 watt amp I have is only producing 720 watts. So the subs are underpowered. That along with the head unit not giving the amp the full 5v until max volume isn’t helping either. It sounds...

All the boxes for the avalanches fire towards the cab. The box sure looks like it’s got a perfect seal. But I could try that tomorrow for the hell of it.

I'll report back shortly. It's hard to find a really knowledgeable shop in my area. I've always had quirks; I had lots of bass roll off issues on my last truck that took multiple trips back to the shop to figure it out. Not to mention a burnt-up amp. I had ordered a 15" Kicker L7R to put...

Thanks, I'll play with this setting when I'm off shift. I figured zero would be "middle ground". I always left head unit bass EQ at zero on all of my previous set ups when running an external bass knob. But maybe on this head unit zero is messing it all up.

Thanks for the big write up. I'm looking at the invoice now, it says these aftermarket 2ohm speakers are compatible with the factory Bose system so I'm not sure how it's wired. I haven't spent any time on the equalizer settings, but I know the Bass EXT is off and the SW level is at 0. I...

Not 100% sure, they just wanted me to buy the 4ohm version of the subwoofer so they could wire them to 1ohm. If they're out of phase, wouldn't it be obvious by watching them move?

I wonder if 4 gauge wire isn’t enough? I plan on getting a second opinion at another shop when I’m off work next week. To clarify, it does bang pretty good but I don’t think it should take 75% of the head units volume to get there. Also, I have to take it back for them to look at the right...

They’re 4 ohm subs wired down to 1ohm. They don’t have the tuning frequency listed on Q powers website for the box. And it’s the Kenwood Excelon DMX709S head unit. I listen to mostly hip/hop, rap and some dance music. I tried the classic bass song Put on by Young Jeezy and it doesn’t play the...

Thanks for the quick reply. I thought the bass boost and gain was a touch high but wouldn’t turning the bass boost to 0 and dialing the gain back a touch hurt the bass even more? Also isn’t the external bass remote tied to the bass boost? I made sure the head unit was all at 0 gain across the...

Hey guys, I recently had a system put in my 09 avalanche. Here’s a quick breakdown of what I’m running. 2 12” Kicker CompR’s, 4.4 cuft ported box, DB drive WDX 1000 watt amp, (Subs are wired to 1ohm) 6.5” DB drive mids and 1” tweeters ran off the the stock bose amp. And a new kenwood head...

Dual 4 ohm driver. I haven’t contacted a shop to build the box yet.

Send the L7 to the moon :LOL:
