4 Channel Amp Help
I recently picked up an entire new audio system to pick up on my highs, since my recently installed sub has been making it hard to hear anything else. Anyway, I went to the local "source" for car audio (bought my sub, amp, and deck there), and the guy sold me a 4 channel amp, a pair of back speakers, a pair of side speakers, and a pair of tweeters. Now that I've got them installed, they are clipping, and eventually cutting out, at very low volumes. I'm thinking it might be something to do with not enough power being put through them.
- The amp is a 4 channel Alpine amp. On the box, it says 50 watts RMS x 4 at 2 Ohms.
- The side speakers are 40 watts RMS. They have an impedence of 2 Ohms.
- The tweeters are 50 watts RMS, also at 2 Ohms.
- The back speakers are 100 watts RMS, 2 Ohms as well.
Now, I'm wondering, is it possible that the speakers aren't getting enough power, specifically, the back speakers? I'm pretty sure the guy told me the amp would run them all, but it doesn't make sense to me that an amp that puts out 50 watts RMS per channel can somehow power back speakers that are asking for 100.
The front speakers and tweeters are wired together in series in the doors (one speaker wire from the amp goes to them, and it splits off to the tweeter and side speaker, respectively). Each pair (meaning one tweeter and one regular side speaker) has its own channel.
The back speakers each have their own dedicated channels, with nothing else attached to them.
Through experimenting with the settings on the amp, it seems that turning the crossover **** all the way up (eliminating lows) and keeping the speakers on high pass stops them from cutting out earlier. I have not messed around with the gain settings.
Any help would be awesome. Thanks.

well if your fronts are run in parallel with the tweeters, without a crossover, passive or active, your a) clipping your tweeters, or b) now you;ve got a 1 ohm load which is tough for your amp to take. These could be part of the problems.
Good luck.
Good luck.

How should I run it, then? I've only got 4 channels for 6 speakers.
EDIT: Ah... damn, my bad. They are wired in series, I forgot. The speaker wire from the amp goes into the side speaker, then from there runs into the tweeter.
Also, are the back speakers alright running on 50 watts RMS per channel when their box says 100?

hI There i mean this in the nicest way possible. Never ever ever install or attempt to tune your own stereo system again lol. The Amp that you have is the MRP F240 isnt it? I had the same one and it has never cut out on me. Hook your speakers up the way they should be, most speakers run best at half their rms rating so stop worrying about that extra 10rms. And your amp wire runs to your crossover box, which holds both the midrange speaker and the tweeter. try that, or have someone who knows what their doing help you.
