RCA plug for sub?
A couple days ago I picked up a kit that included a 150W RMS 2 channel amp (4 ohms bridged) and a 10" sub with a sealed truck box.
Here's a link to it, as far as I've found, it's been discontinued.

I've got the two rear 6.5's connected, as well as the sub (bridged).
Is that an acceptable way to hook them all up?
Also I wan't to make removing the sub box easier, so I picked up an RCA plug and jack, and am thinking about putting it on the side of the sub box. Right now it's got the spring clamps in the back (bottom) of the box. Any reason an RCA jack wouldn't work for this?
Thanks for any opinions

I'm not quite sure I follow you, Carl...
I looked at the link to the sub/box/amp. You mention the 6.5 inch drivers, but you don't mention how you are hooking them up.
If it was me, I would use the amp to drive just the sub, not all of your speakers.
If you are trying to run all three speakers (6.5 speakers and the sub) from that amp, you will have problems.
(Unless you go with a custom designed crossover.)
As it is right now, your amp will 'see' a 4 ohm load for the sub, but by introducing the 6.5" speakers you just added another 8 ohm load to the amp... lowering the overall impedance to the amp to 2.666 ohms. This will cause your amp to heat up and ultimately fail. (Unless you are using a passive crossover specifically designed for the sub and 6.5" speakers.)
If it were me, I'd run the 6.5' speakers from your head unit, and only the sub on the amp, with the low-pass crossover set anywhere between 60-120 hz.
Hope this helps.
