NightmareImpala

Thank you for all the advice. I will run a zero gauge cable to the alt mounting bolt to - battery terminal because I didnt think I needed one with my ground mounted where the factory mounted a ground to the engine block(which I did clean and make sure it was solid). I will also avoid playing music at high volume at idle speeds. It def performs great when I increase the rpm's to around 1500 - 2000 rpm. I am very pleased with my mechman alternator just so you know. Great customer service. Thank you for your timely response

Yes

I will try that tomorrow morning

No it only does it when the system it at full tilt and it just spikes down to 12.5 v. Maybe it could be a ecm problem

I believe it idles at around 800 rpm

Thats what I am wondering. What else could it be? My engine def bogs down when I am at full tilt too maybe that has something to do with it?

Pretty sure I have nice clean grounds and the amp is wired to .5 phms right now until I get my other 2200. I guess I will have to recheck my grounds and maybe ground directly to the frame. Would that help?

I have a mechman 270 amp alternator in my 2005 lS with a mechman adjustable voltage boost module set to charge at 14.8 hot... Current setup is 2 xs power d3400 batteries 1 aq2200 Big 3 done with 0 gauge kicker hyperflex wire And 2 btl 15's Is it normal to have my voltage drop to 12.5 at idle with the system at full tilt? I wanna add a 2nd aq2200 and I am worried that my voltage will drop even more. When I hit the gas pedal and keep it at around 1500rpm the voltage stays in the mid 14's but I just want some outside input on this..

Yes TWO 15's lol. The box is just under 6 cu ft I believe ported and tuned low to 33hz. I know each sub is seeing at the minimum 2.5 cu ft each after all displacement. Getting a pair of 15's in that trunk was difficult to say the least

Havent had in on a termlab yet. If I could find someone local that has one I will def see what I can hit. I had it metered @ my buddys audio shop with some spl meter setup he has and it says I was hitting 149.2 but I doubt that was very accurate especially only on 2500 watts in a trunk build lol

Ported on drivers side. Tuned to 33hz

first test run with my newly installed btl 15's at the local cruise night. Powered by a aq2200 @ .5 ohms (until I get my other aq2200 that is) song is chp "wet dolphin" chopped & screwed

thanks! I just re-copied and pasted the url and it worked

Try this link:

Thats strange ....it works when I click the link. Is there another way to add a vid on here?

What do you mean? Link broken?

here is the first flexx vid of my new setup taken on a evo cell phone shot in 720p by (SMD member) kryptonite.....more vids to come and I am getting my 2nd aq2200 in a week. http://m.youtube.com/index?desktop_uri=%2F&gl=US#/watch?v=RimQkiof9Ow

Honestly I am not sure....i will have check tomorrow

U cant see in the pics but the port is where the trunk opens up but I would like to have more room than I have

We impala guys have good trunk space but the opening is def limiting to what you can slide in :-( I am gonna make some vids this week as I just installed everything today.

Thanks guys...the lows are pretty violent lol. I cant wait to throw moar power at them!

Yes def works well. Brutal low end bass lol

Port on left side (drivers side) and I will post some more pics when I get home

Old setup.....pair of d1 fi bl 12's powered by aq2200 @ 1 ohm. 4 cu ft box tuned to 32hz (ported of course) New setup.....pair of d2 fi btl 15's powered by a aq2200 @ .5 ohm (soon to be a pair of 2200's strapped) new box is 6 cu ft tuned to 32hz. (ported of course) Hell of a time getting a box that big in that 05 impala ls trunk lol What do you guys think so far..?

I have placed several orders with ddmtuning .com and havent haf any issues with them. Great product and cant go wrong with a lifetime warranty. One thing I learned is if your impatient like I am ( lol ) then pay for faster shipping or you will be waiting 2 - 3 weeks to receive your order
