Hey guys, new to the whole amp/sub scene. I have installed 100s of decks and new speakers but never ventured into anything more powerful. I have an old school punch 75HD amp coming. I also have 2 fosgate subs that this will be powering. Whats the best way to wire it up. And i can ground to my frame right? and also anybody have a guide to building stealth sub boxes for an echo HB (dont laugh).

 

4 awg from battery to amp with fuse id say 50 amp will do,ground to metal body ,how much frame does an echo have anyways?lol.
Run a remote lead from deck on the same side as power wire and run rca's on oppisite side to avoid signal noise(interference).
I have a 45 hd and never had a problem running it at 2 ohms bridged,barely even got hot! This however is at youre risk, it will crank at 2 ohms bridged btw hehe

What kind of subs you running? 4 ohms,2 ohms>?

^^ sub so 4 ohms.
I have a sony gt-100 deck in there.
as for the 4awg, going from bat to amp, http://cgi.ebay.com/KnuKonceptz-4-Channel-4-AWG-Amp-Kit-Blue-Silver-NEW_W0QQitemZ220072984669QQihZ012QQcategoryZ71528Q QcmdZViewItem
that will work correct?

 

I'm confused. Maybe you should read your original post?
Does it really say that you just bought an amp and it will be powering 2 amps?

 

umm, yup. but shhh, dont tell anyone. for some reason i keep calling my subs amps, keeps messing with people.
