Default Audio question - adding another amp

Last summer I removed all the Bose stuff, and installed a new Alpine HU with Ipod integration, etc. I'm currently running one bridged amp to a 12" subwoofer. I put new 6x9 Alpines in the doors and the little ones in the back. Last year, I only ran the 4 speakers on the deck power. It sounded very good, but after about half volume was all distorted of course.

So..... I'm thinking of adding another 4 channel amp to power the 4 speakers. To do this, can I just splice into the existing amp's 12v power wire, and just run a bigger fuse up at the battery? Amps will be located right behind the waterfall (convertible). Also, what do most people do for the speaker wires that now have to run from the new amp- just run them up the tunnel to the H/U area to pick up where they currently go to the deck powered outputs?

Simple questions, I know..... thanks!

You need a fused distribution block. How big is the wire from the battery?

I ran new speaker wire along the door sills, into the door panels directly to the speakers. This is the easiest car in the world to run wire in.

If the gauge of power wire is sufficient, you should use a distribution block to split it, each with it's own fuse. Then the add the fuses together to know what size fuse you need at the battery.

Preferably, all RCAs should run down the drivers side, next to the sill. You will see other wires and stays along that crease. Power should run along the passenger side. You want them as far away from each other for sake of interference. The speaker wires can run along those same sills, left on the left side and right on the right side.

HTH,

Speed

You fuse based on wire length and current capacity... Be careful, because you can use too high of a fuse if you do this.

The fuses protect the wire, which is why its important to have the fuse as early in the line as possible.

One within 12" or less of the battery, then one for each line coming out of a distro block.

This is a site that plays it on the safe side and will tell you how you should do your wiring and fusing.

I'm trying to decide on a system for my car...
I've seen a few people installing a single 10 or 12 in the "storage" in the rear middle compartment

______________________
Just got done doing all the wiring for a buddy's car today (mudstain)

Hes running 2x12" pioneer premier (4ohm) (the competition ones..)

anyways, 1000 watts rms/3k watt peak

Powered by a mono channel Hiphonics Brutus amp

Running dual voice coils in parallel(2 ohm per speaker), then then two speakers in parallel to get down to 1ohm

Ran 0ga wire for positive and negative to a 2nd battery in the trunk.. then 0ga from batter to amp
