Thoughts on this amp(also buying used question)

I have already bought the HU, speakers and amp I was going to install. Now as I get closer to installing I am concerned the KTP-445 powerpack won't be enough. It may be I don't know. Maybe I just need to stop reading the internet. haha...but I also don't want to install somethign and not be happy. Again, maybe I would be happy though.

Anyhow....so looking at amps it makes sense to get something more than the 45RMS of the KTP-445....the speakers are the Alpine SPR-17S rated at 110 max RMS.

But I also want to stay around $200....I see this amp on CF for 249 and half off a wiring kit....but 70RMS for 250 is about the best I found.

Also I have been looking locally on Craigslsist and wonder what you guys think of buying off CL? I know all about the scams and have bought and sold quite a bit on CL...but not car audio. There is an Alpine PDX-4 with wring kit near me for $300....I was thinking of offering 250....it said was used less than a year. Any experiences with buying used? Really bad idea? What would I look for as far as knowing if it is damaeged?

Thanks for any comments

 

More power is almost always a good thing, but is not always needed. With that said, I would consider your actual needs - are you trying to improve the sound, or get loud?

The volume difference when doubling the power is only 3db - not a huge deal. Were it me, I would take the extra cash and spend it on better components, or split the difference and get something like this:

I have had no real issues buying used, but I test things first if local, and deal with people I trust otherwise. Forums where I frequent (such as DIYMA, and a few others) let me know better who I want to buy from.


With that said - you already have some stuff. Unless you can return it for a full refund, why bother - Plus, you will probably be happy with it. If you decide you want to upgrade in the future, you can. If you are happy with it, then rock it.

I can make tons of recommendations, find lots of deals, especially on used gear, but only you can decide if that is the route you wish to go.

Good luck!
