need help on how to install a alpine era-g320 dsp

i've had a few of these, and ran them for years.
yes, the harness is short and it is expected you power it from the amplifier power distribution block, or extend wiring. you'll need amplifiers anyway and this is best located back by the amplifiers.

it is compatible with any headunit with RCA output but best suited for use with an Ai-Net Alpine head unit (CDA, DVA, IVA series). Ai-Net cable offers both audio and control in a single cable. You need the remote display controller to make adjustments. It is the same size as a single DIN head unit. I located mine in place of the overhead sunglass holder.

i've also ran the Alpine PXA-H701 with RUX-C701. It was much more flexible than the G320 (which I originally owned in the late 90's).
I currently run the Alpine PXA-H800 with RUX-C800. The H800 is by far the best they've made yet.

The main advantage to running Alpine processors is using their head units for control (especially volume control) and having remote displays that allow tuning (most require a laptop). Dragging out a laptop to make an adjustment is a PITA. The H800 allows for laptop tuning, but only necessary for their Imprint tuning. Manual adjustments are through the controller.

MiniDSP units are cheap and flexible. 100% laptop with no interface.

Audison Bit series offer a display for some preset recall and volume adjustment.

Rockford, PPI, etc. have processors in boxes with laptop tuning.

what processor to use depends on what your goals are. the G320 was noisy, with an audible background hiss at higher volumes (audible during track pauses). it was limited in EQ, had time alignment, but lacked any crossovers or phase or level adjustment of modern units.

that's very interesting. I suppose there aren't many other processors with reverb like it.
The G320 pops up on eBay every so often. usually sells for $200-$400 depending on the condition, packaging, and market. Best way to find it is hit up audio forums asking for them, checking audio forum classifieds, eBay, etc.

I wouldn't buy this one for the damage

This one appears to lack the brain and wiring (but is an example for how valuable the controllers can be)

make sure you get the 17' controller cable with it. do you have an Alpine Ai-Net head unit to pair with it? it's my strongest recommendation you do.
