Ok ive been asking on here, and cant seem to find a simple answer. Or the people im asking dont sign in for a few days!! lol!

I have a 2010 STX that i have upgraded the door speakers. They sound fine, waaayyy better than those stock ones. However i keep reading about this Alpine "power pack" amp, I think its KTP-445u??? its a hidden amp, that (i believe) you can install with the PAC adapter to the stock HU. Is this correct?? Im looking to get this sound system better, but i do not want to add a sub or anything.

Thanks

It is a small amp that increases the HU power. Small enough to fit inside by the radio. It is made to plug and play with certain Alpine HU's but can be used by adapting the PAC wiring harness

Search for the thread on here. There is one with install pics and instructions.

Will do, once on a computer...as my search function on my phone doesn't work so well

No need to bother with that PAC adapter. Save some money and get the Metra BT-5520...it's the adapter featured in that thread with the Alpine amp.

I assume that one is better? Seems like that one is for non amped trucks...which is what I have. I just have the standard stereo. 1 disk cd, no sat, so sync, just an ipod(aux) input

It's the one I went with. Got it for around $25-30 vs around $50 for the PAC adapter. There's already a great write up on how to wire it up on these forums. There's a post or two discussing the PAC adapter in that thread as well...but the Metra adapter seemed simpler to do and was cheaper, so I went that route.
