Alpine iLX-507 7" Multimedia Bundle

This Alpine bundle combines a 7-inch multimedia receiver with a compact 4-channel amplifier and two pairs of R-Series coaxial speakers. The iLX-507 head unit provides wireless smartphone connectivity for Apple CarPlay and Android Auto. The KTA-450 Power Pack amplifier and R2-S65 and R2-S69 speakers complete a full audio upgrade in one package.

Drivers replacing a factory stereo

This kit suits owners who want wireless Apple CarPlay and Android Auto on a 7-inch display plus amplified sound for four speaker locations. The bundle includes front and rear speaker pairs matched to the amplifier's four channels. Buyers who need a single-DIN chassis, a larger floating screen, or a multi-channel processor for separate subwoofer control should look at other solutions.

45W RMS x 4 amplifier output into 2 or 4 ohms

The KTA-450 delivers 45W RMS per channel across four channels at both 2-ohm and 4-ohm loads. This figure determines the clean power available to the included R2-S65 and R2-S69 speakers, each rated for 100W RMS. Matching the amplifier's continuous output to the speakers' power handling ensures the system plays loudly without distortion.

Questions about this item

How is the KTA-450 amplifier installed and what step is often missed?

Mount the compact 7 x 3.5 x 1.25 inch Class D amp behind the dash or under a seat, run power from the battery with a 40 A fuse near the source, then connect its speaker-level inputs to the iLX-507 harness; the step most installers miss is setting the DPP gain correctly so the 45 W RMS x 4 output stays clean at 2 or 4 ohms.

What maintenance will the R2-S65 and R2-S69 speakers need later?

The Hi-Res certified 6.5 inch and 6x9 inch coaxial speakers have no user-serviceable parts; simply keep the grilles clear of debris and re-check the terminal screws after the first few hundred kilometres of vibration.

What limit appears first when the system runs at high volume for long periods?

The KTA-450 amp will hit thermal protection before the speakers reach their 100 W RMS or 300 W peak ratings, so sustained output settles at the amplifier's 45 W RMS x 4 continuous limit.
