Help!? Alpine power pack

Recently after my research on here I purchased a alpine cde-147bt headunit, alpine power pack and Polk db 6.5 rear 5.25 front. My problem is I turn it up too about 23 on the hu then after bout 10 secs the hu turns itself down then back up to 23. I didn't solder my wires and I only used that strap on the back of the factory radio as a ground. Do I need a heavier wire for the amp? Better ground. Also I adjusted my settings on my hu I set the frequency to 50 hz for front and rear and it didn't seem to do it anymore but I have never had to do that before on anything.

Probably grounding out. You need to solder any twisted wire connections and either wrap them with shrink tube or electrical tape. Alpine units usually come with a heavy gauge ground wire with a ring, pick a bare metal spot in the dash/firewall and screw it down.

So I figured it out, the setup wasn't getting enough power from factory wire. I ran a 12g hot straight from the battery to the constant wire works perfect now. Very loud easy and awesome setup.

I have the exact same issue with my 2000 TJ sport. I have to use the low gain setting on the power pack due to the "clipping" when turned up to 22 or 23 on my alpine radio. I had installed heavier gauge wire on my jeep, essentially doing a big 3 upgrade to support more electrical upgrades later and it helped out the clipping zero! Did you bypass the harness with the 12 gauge wire, or go strait to the harness and tie in there?

I went straight from the battery directly to the yellow wire on the power pack and put a inline fuse next to the battery. My power pack does not have a high or low gain switch they must have changed it on newer models. This did solve all my issues my dash lights don't dim anymore and it sounds hundred times better.

From the KTP-445U manual:

• Battery Lead (Yellow)

There are two options:

a. Connect battery lead to OEM radio fused circuit.
The OEM radio circuit has a fuse to protect your
vehicle's electrical system in case of a short circuit. Do
not connect the battery lead to the OEM radio circuit if
the fuse rating is less than 15A.

b. Connect battery lead directly to BATT+
Be sure to add a 15A fuse (sold separately) as close as
possible to the battery's (+) terminal.

All the wire in the world wont keep an amp from clipping when youre pushing it too hard.
