need help deciding on my audio build

RonRizz

The 165k's are $600. the isc100's are $150. That's $750, not $1600++ unless you're using common core. lol. but seriously;
The 165kr are rated at 80w rms, the isc100 at 40w rms. The amp is rated at 100w rms, more than enough to drive these speakers to their potential and beyond. If the OP were interested in, say, competing in Iasca or Meca, I would recommend something else.
Costs more doesn't mean sounds better. Something I learned a looong time ago.

Mr Pinchy

Don't know what you mean by "common core" but I was using full retail for both sets of speakers and head unit. So your saying an amplifier with a higher Signal to Noise Ratio and Lower Total Harmonic Distortion won't sound better than the Soundstream with the Focals? If that was the case, in your opinion, why not spend a lot less on the speakers too since they will sound the same as expensive ones, or is that just amplifiers? I just wouldn't spend all that money on audio then go cheap on the amplifier.

I don't recall saying that anywhere in this thread. Please point that out to me. If the OP chooses, he can buy a couple Milbert tube amps for about $8k. Offer the OP a suggestion for a suitable amp, or move along.

Just a side note to this comment unrelated to this thread.... Did you know that Alpine had a component set on the market called F#1 Status, and the Mids alone in that set were retailed at $3800 I believe. I heard a set in a Q35 at SLAP Nationals in 2005. They were amazing.
Turns out, the Mids were rebadged drivers from the Scanspeak Illuminator line, which retails at about $460 a pair. This just popped into my mind when I read that comment, that's all.

I am not trying to cheap out on the amp... I never gave a budget price on how much to spend on it, but of course nothing too outrageous like a 2k+ amp lol..
like I said in the earlier post.. i am below average when it comes to audio even after reading the sticky on audio 101 from Big haha
that is why i created this thread and ask for suggestions.. just need a good amp that can power these speakers up and bring out what these speakers can do.

Mr Pinchy

Sorry Nismo13807 didn't mean to imply you were being cheap. Just didn't make sense that you are using high end speakers with an entry level amplifier. That being said here are three amps ,of many, I have used or are currently using and I am very pleased with them all. They are all four channel and can be purchased from $325 to $450 at this time.

I like to experiment with various brands. These will provide exceptional sound at high levels with no distortion.

Also you mentioned you do not want a sub. The speakers behind the seats add almost no sonic impact or overall quality to the sound of the system. My feeling is a sub would contribute much more to the sound of your system. Zenclosures makes an awsome enclosure custom built to fit our cars. They will even adjust the cabinet airspace to your sub's requirement. I have this with a 10 inch sub and it sounds incredible. You could also purchase a sub enclosure and attach it to rear deck but I really like the finished look of the Zenclosure. Any of the amps listed above are bridgeable meaning you can combine one rear left and one rear right channel as one to drive one woofer at 200 to 250 RMS. When and if you decide to add a sub. Hope this helps.
