Isuzu i-370 Speaker FAQ

What speakers fit the Isuzu i-370 door panels?

Both front and rear door panels use 6.5 inch speakers. The front doors accept coaxial or component speakers, while rear doors can handle coaxial, component, or full-range types. Standard aftermarket 6.5" speakers should mount without modification, though you'll want to verify mounting depth in your specific i-370 before purchasing.

Should I prioritize front or rear speaker replacement in my i-370?

Replace the front door speakers first. Your ears sit closer to the front soundstage, so these 6.5 inch speakers have the biggest impact on audio quality. The front position also handles more critical midrange frequencies for vocals and instruments. Rear speakers mostly fill in ambient sound... unless you're running a full component setup where rear fill becomes more important.

Can I mix coaxial and component speakers in the i-370?

Yes, but it gets complicated. You could run components up front for better imaging and coaxials in the rear for simplicity. The Isuzu i-370's wiring should handle both types since all positions are 6.5 inch compatible. However, matching sensitivity levels becomes tricky - components typically run 87-89 dB while coaxials might hit 91-93 dB. This creates volume imbalance that requires amplifier adjustment.

What's the difference between full-range and coaxial speakers for the rear doors?

Full-range speakers focus on mid-frequencies, typically 80Hz to 8kHz, without separate tweeters. Coaxials add a tweeter for extended high-frequency response up to 20kHz. In the i-370's rear position, full-range might actually sound more balanced since you're not sitting directly in front of them. The tweeter in coaxials can sound harsh from the rear... but depends on your listening preferences and whether you're running a subwoofer.

How much power do 6.5 inch aftermarket speakers need in the i-370?

Most quality 6.5" speakers handle 50-75 watts RMS comfortably. The i-370's factory amplification probably outputs 15-25 watts per channel, so you're not fully utilizing speaker potential without an aftermarket amp. Component speakers often need 60-100 watts RMS to really shine, while coaxials can sound decent with less power. Check impedance too - 4-ohm speakers will pull more current from your head unit than 8-ohm versions.
