Help needed to wire stock H/K speakers to 4 channel amp
I am replacing (most of) my H/K system this week and I am at a point where I need some help.
I am keeping my stock H/K speakers (for a while at least, to hear how they sound) and want to hook them to my new Alpine 300W amp. It is a 4 channel amp.
I have added a subwoofer powered by it's own amp, so I do not need to do a bridge or anything, so let's just take it out of the equation.
Keeping the stock speaker wires is attractive, but not required. I have the car pretty much stripped right now, so if I am going to run new wires, this is the time to do it.
The questions I have are:
If the amp is going to run 75W per channel, what gauge wire do I need for each speaker? Do the tweeters require as large a gauge as the others? If I replace the wiring, I will probably solder the leads onto the speakers, BTW.
How do I connect each channel to the correct speaker? I do not have the time to 'learn' enough to delve into this on my own, and I would rather not take it to an audio shop, but will if I have to. I have 3 sets of speakers, one of which is dual coil. How do I conect to the amp?
If any of you guys have experience in this, I would appreciate a little assistance. Thanks in advance.
BTW, the new system is the following:
receiver..... Sony MEX-BT5700U
HD Tuner .... Sony MTX-100
Amp... Alpine MRP-F300
Sub amp..... Alpine MRP-500
Subwoofer.... Bazooka BT1214

You better search through some old threads because I don't believe the speakers will work by just plugging them in to the 4 channel amp. The wire gauge isn't a problem. If you have the same system I did the H/K speakers I believe are 1 or 2 ohm. I'm not positive but I thought when I was doing my system I saw some way of wiring to work with a normal 4 channel amp.
Sounds like you are planning something similar to mine. A sub amp and a 4 channel for the backs and fronts. I'm running MB Quart and it sounds great. You can see it in my gallery if you want. Although a just changed my sub amp.
Do you still have the HK amp? does it work? If so, I got $600 for mine on ebay.

Philip,
What you are suggesting is not going to give you good results without a lot of extra work and expertise. You need to divide up the frequency spectrum among the various speakers. This is done electronically inside the H/K amp. Most aftermarket speakers do it passively with an external crossover. An external crossover would also be necessary to deal with driver impedance issues (this is not an issue in the H/K amp because it has 8 channels). You could build the necessary crossovers, but you'd need to learn an awful lot to do that and you'd spend many times more on the crossovers than the H/K speakers are worth.
Additionally, the H/K speakers are reasonably well optimized for efficiency within their power handling limits, so you wouldn't get much benefit from an aftermarket amp anyway, and you would have to deal with all the problems listed above.
