electrical upgrade?

[bobgrey]

I have two pioneer champion series pro 10" ts-w2502d4. Rated 800 RMS each. I'm looking at ordering the hifonics brx2400.1d because of how inexpensive it is ($230), I know that it's a lot of headroom but that leaves a lot of room to upgrade subs later. My last system was two diamond d3 12"s (400 RMS each) so I've never had a system over 1kw. So I have 4 ga wires all around stock battery and alt.

So while I'm running these 10s and the amp at 50-70% gain do I need to run some 1/0 ga wires and consider an alt? Or is it fine as is.

Get them in, definitely go with a 0 gauge wire kit along with the big 3 upgrade(google it up) Get a 2ndary AGM battery to the rear if you can aor go straight for a higher output alt. However i would wait till i get the whole setup in and measure your voltage drop with the multi meter first, it'll give you a sense of how much upgrades you'll actually need.
