AMP3 in my car for 8" subs

[GhettoSQ]

Hi all...my new mustang came with 2 8" door subs and 2 crummy little amps, about 100W each. The factory woofers are 2 ohm DVC but I replaced them with 8 ohm Seas CA21RE's -- needless to say I need new amps. I think I can make 2 AMP3 kits from 41hz.com, each bridged for about 50W into 8 Ohms.

What I'm curious about are the details, since I'm very new at this. The factory amps are hooked up with harnesses, so I need to figure out which wire is which and how best to connect them to the new amps. I also need a way to determine if the factory amps are using line-level or high-level inputs; they look like speaker cables going in, but it would be good to be sure before I shell out for a LOC.

Finally, what else do I need to know here?

the amp3 kits have their outputs already bridged internally. which means you cannot bridge amp3 outputs.

argh, i know, i just found that out...*sigh* back to the drawing board...

So, I'm basically looking for a kit that will do 2x100W @ 8 ohms, give or take. I'm also open to just buying an amp since the kit options seem limited.

What's my best option? a 2-channel that can do ~80-100W into 8 ohms per side, or a monoblock with 200W @ 4 ohms, both woofers wired in parallel?

thanks!

I'll bet that the factory wiring leaves a lot to be desired. You might consider running new wiring when you figure out what you are going to do.

You're probably right...still, I'm hoping to find a solution that will work as close to PnP as possible for now, and maybe upgrade later.

Tripath recommends their TAA4100...it's the new 4x100W head unit chip. Hot stuff. Unfortunately not bridgeable but I imagine I could find something to do with those extra 2 channels. Unfortunately I have not seen any kits for it yet

ide say wire the speakers in paralell and get a and get a 4 channel amp like 800watts wire them on one channel and add some more normal speakers for the other 3 channels (mabye rear sub or 2 and some dash and rear deck mids)
